| 1 | Sinusitis | Lack of sleep big time. | It's 5:55am and I could not sleep last night. It's was my first time takingit and I'm not sure I can take this another night. Plus I'm experiencing throut tightness. | F | 28 | 2X D | 7/26/2010 | 3 | seasonal allergies | I take Allegra with no problem.....but my son is the one I am talking about. Since he has been on it, his mood and anger levels changed slightly till recently...he slowly got worse. Then lately he has had anxiety, not wanting to go out, and alot of crying?! He has had alot of stomach and constoption problems in the last 6 months! All these things are getting worse and I thought my husband and were going crazy...he's off of it as of right NOW!!!Than I talked to a friend that said check out the symtoms of the Allegra and I found this website. Thank You!!!!! | Hey ALLEGRA what about these symtoms!!! | M | 9 | 30 months 30mg 2X D | 7/16/2010 | 2 | chronic sinusitis | agitation, nervousness, hot flashes, unusual thoughts, stomach upset, nausea, fatigued | I normally take benadryl for my constant runny nose but when I want to add a decongestant, I take allegra-d for maybe one day a week. Allegra-d makes me very focused without too much stomach upset, but I took a regular generic allegra the day after the allegra-d and I felt stomach upset right away, nervous and now non-stop hot flashes. I am agitated, tired and nauseated still. | F | 51 | 1 days 1X D | 7/9/2010 | 2 | Allergic rhinitis/bronchitis | Thank God I found this site, or I'd never have known my reactions weren't all in my head! Others out there have had the same experiences with Allegra that I have, but none are mentioned on medical websites EXCEPT THIS ONE, where PATIENTS SPEAK. | F | 57 | 180 1X D | 6/29/2010 History | 2 | allergies | moody, angry, depressed, agitated | I had the same type of problems with zyrtec only with that, I started getting real paranoid. I think there is something wrong with these drugs, mess with your central nervous system too much. I am usually a happy go lucky guy, but on this, Mr Hyde's bad side came out big time. My wife carried a ball bat around with her with my name on it.... whew... just kidding, but she was loosing patience with me fast..... be careful with this. I am sure some people have to take it, but be aware of any changing behavior problems. | M | 48 | 10 months 180 1X D | 6/28/2010 | 2 | ? | F | 79 | 180mg 1X D | 6/20/2010 | 3 | seasonal hayfever | This only works on me for a few hours and then I seem to have really bad attacks later in the day. Has anyone else had this? I have also felt "flat" more or less since taking it, which I had not equated with this drug. However, I went off it when I was out of town and away from allergans for a few days and I did feel much more myself. Yipes, it didn't even occur to me that it had mental effects. | Given the range of reponses to this drug, it seems that you should keep a syptom diary while on it it see what is up - I wish I had! I liked seldane much better and had no side effects from it. I get no help from Claritin or Zyrtec. | F | 43 | 2 months 180mg 1X D | 6/14/2010 | 5 | allergies | mild dry mouth | only antihistamine that I can tolerate | F | 45 | 30 days 1X D | 6/12/2010 | 1 | Allergies | EXTREME Anxiety, Depersonilization, Derealization, Depression, Panic Attacks, Frain Fog, Exhaustion, Memory Impairment, Weakness, Fatigue, etc. This was regular Allegra (Not Allegra D). This is one of the worst medications I have ever taken in my life. Nearly put me in the hospital after 4 days. I literally felt like I was dying and having a mental breakdown. Symptons started to go away shortly after stopping. | I do not recommend this medication to anyone for anything. Even if you "think" you are reacting well to it, chances are it is doing some underlying damage to you that will eventually catch up with you or come to the surface. There's a bunch of crap in these pills that mess with your neurology, digestive tract, and limbic system. | M | 29 | 3 days 1X D | 5/25/2010 | 4 | allergies | generally I take this when allergies come up like cats, and it helps. I don't really notice much effect other than that my allergies go away. Now taking it on a regular basis I notice that I do get a little more tired, but that's just the price you pay for not having allergies. All and all I am VERY happy with this medication! | F | 28 | 2 months 60 to 120 1X D | 5/18/2010 | 3 | allergies unknown | I have migraines , but not for awhile. I had a terrible headache all night long on the first night I took it. | I am sure it triggered a bad headache for me. It did dry my congestion very well. | F | 62 | 1 days 180 1X D | 5/18/2010 | 1 | Allergies | Severe anxiety, depression, no motivation to do anything, horrible heartburn that would keep me up at night, at first I was hungry all the time then I experienced loss of appetite. I thought I was having a mental breakdown and was ready to go see a therapist and then I realized these issues started around the time I started taking Allegra. I do not take the generic pill. I will stop taking immediately. Thank you so much for running this blog! | F | 34 | 7 weeks unsure 1X D | 5/17/2010 | 3 | cat allergies | It helped with the allergies, but every time I take it I get a headache, irregular heart beat and extreme anxiety. | F | 63 | 7 days 1X D | 5/16/2010 | 1 | allergies | I have had dizziness, and headaches right after taking this med i dont think this helps at all i think the side effects are worse than my allergies, even though i have real bad allergies i do not like the side effects will be trying soemthing new next visit | F | 28 | 60mg 2X D | 5/11/2010 | 3 | dust and mold allergies | No side effects, as I had w/previous allegry meds. But, after taking for 18 yrs, and changing my locale to a different climate, it was ineffective. Changed to ZYXAL-forget it! It worked for 1 1/2 months; then nothing. Only change with XYZAL was an 8 lb. gain over 8 weeks. Thinking about going to Allegra D. | I never experienced being tired nor nervous the whole time I took Allegra. | M | 66 | 18 years 10 mg 1X D | 5/9/2010 | 1 | Bad allergies, sinuses | I'm an anxious person, but I had my anxiety under really good control when I started taking this medicine. After a couple days of taking Allegra, I couldn't function. I was having panic attacks non-stop, I didn't want to do anything, my stomach hurt, I could barely eat anything, I couldn't sleep. I got like 4 hours of sleep every night. Once I stopped taking it, I felt like I was back to my old self again, and wasn't constantly freaking out. | I wouldn't advise taking this if you're already an anxious person, because for me, it made me feel absolutely TERRIBLE. You could try it and see if you feel okay on it, but if you don't, stop taking it. | F | 20 | 6 days 180 mg 1X D | 5/8/2010 | 4 | Chronic Sinusitis | Grogginess which leads to irritability as I am an active person, jogger, do it yourselfer to the home and my Moms house. I also take Singulair and Nasacort to help me with my sinusitis. I did have septoplasty surgery 2 years ago and that helped me more than anything else, but Allegra keeps my hives under control. These drugs are wonderful but I've realized the side affects are also real and can cause tiredness, depression and headaches that makes me wonder if it's worth taking them but then I recall what is like without them and at times I could barely function or think with the tremendous headaches and dizziness I was experiencing. | Before I decided to take Allegra on a regular daily basis I would break out in hives and on occaision my lips and tongue would swell up. I also have an allergy to cold temperatures and Allegra helped me tremendously against that. There were times I was completely lost as to what was happening to me as I suddenly had these terrible sinus headaches and dizziness where I could hardly even stand up. I stopped responding to any antibiotics including Levaquin (sp?) which is supposed to be the strongest available. I did the allergy shots from age 39-45 and also all the meds but quite honestly until I had sinus surgery to remove a polyp behind my right cheek in my nasal cavity and had my septum straightened out I started to regress to the way I was when I started feeling so bad when I was 39. Not sure if this helps anyone but I got a second opinion about my polyp and septum and that Dr. felt it was very necessary to do the surgery. Don't be afraid to do what is right for yourself even if means offending your own Dr. | M | 46 | 3 years 180 1X D | 5/2/2010 | 5 | If you've had racing heart and anxiety from allegra you're probably taking allegra-D, which also contains a decongestant. I take allegra every day but cannot take allegra D because it causes heart palpatations. The decongestant is too strong. I take sudafed as needed and take half the normal dose because i'm sensitive to it. Stop taking allegra D and take regular, and add a decongestant only as needed and where you can control how much you take. | F | 49 | 1X D | 4/30/2010 | 5 | Rashes | None | Completely cured my horrible rashes. I think it may be diminishing in effectiveness slightly over time. | M | 52 | 20 months 180 1X D | 4/26/2010 | 1 | Fluid in ears | Mood swings, depression, loss of appetite, nausea, headaches, severe upset stomache. | Although my ears are no longer getting plugged, I immediately started getting headaches everyday. Severe stomache pains started 2-3 days in. I felt like I was going to throw up every time I ate. By day 5 I could barely get out of bed I was so depressed. I have never been down or depressed in my life. This lasted for 2 days. Today I feel fine but my ear was plugged for half the day. I plan to stop taking Allegra. | F | 26 | 7 days 180mg 1X D | 4/26/2010 | 1 | allergies | F | 32 | 2 months 180 1X D | 4/11/2010 History | 1 | allergies | fluid feeling in ear (popping sound, fullness) horrible throat tightness | day 1 - horrible throat tightness. Everyone kept telling me it was just stress. Day 5, fluid feeling in my one ear. Then the other one. I found this site on day 9 and stopped allegra. What do you know, throat tightness went away. This was back in January. It took until now (April) for my ears to get back to normal. Doctor said it can take a few months for ears to heal. My throat gets tight every now and then now and it never did before. I think my throat muscles just remember that horrible feeling and every time I get stressed, those muscles are now the first to tighten. Has anyone else experienced this? Horrible medication. | F | 24 | 9 days 1X D | 4/9/2010 | 3 | allergies | Anxious, heart beating fast or abnomral. heart palps, just not myself | I have been taking Allegra 180 for at least 3 yrs now. im now having panick attacks, heart beating out of control at times, restless and cant sleep. Asked mutiple docs if this med is doing this too me. All of them say no. Ive never had pannick attacks until now. Ive worried myself to having high blood presure and now taking lexapro for the anxiety. Sometimes I think Allegra has caused the high blood presure. I just want to be well. | M | 31 | 180 1X D | 4/7/2010 | 1 | allergies | anxiety, nervousness, jittery, dizziness, headache, insomnia. | was prescribed Allegra D 24 hour for allergies, I took the prescribed dose for 2 days, the first day I had a little headache in the evening, but could not sleep, had racing thoughts. Took it the next morning, and a few hours later felt like I was about to have a panic attack, really nervous, slight dizziness, headache, just a weird feeling. Will not take again...sticking with Zyrtec | F | 38 | 2 days 180 1X D | 4/6/2010 | 1 | allergies | they are all really bad zyrtec allegra sudafed benadryl the best one is advil cold and sinus go out and buy it asap i did not experience any side affects like all the other garbage i listed on top | nasty like all the other antihistamines nasty nasty | F | 31 | allegraD24 1X D | 3/28/2010 | 1 | allergies | heart racing, panic attacks | Had dizziness. Dr thought might be allergies. Prescribed Allegra D 180 (also did MRI and Ear/Eye/Throat Dr.) Took Allegra D 180 for 2 weeks. Heart was constantly racing & hard to breath. Started having anxiety. Ear/Eye/ Dr told me I needed a shrink. In Er 2 days later with heart at 159 (I run 120). Er dr told me I was stressed & sent me home. Original Dr had to give me a shot to lower my heart rate (the next day) I went through this heart rate all night at home. Figured why go to ER if they thought I was stressed & werent going to do anything unless I stroked out or had heart failure. Then the DR did tests on my heart. (I originally went in for my head!) After 6 months Dr told me I was fine. By then I was on Paxil, still panicky & still had the original dizziness they never figured out. Got a NEW Dr. Took me off Paxil and gave me ativan for as needed use. Still have panic attacks regularly. They told me when the medicine cleared my system I would be fine. THIS HAS BEEN 6 YEARS. I excercise 2 or 3 times a week and am constantly on the go. So excercise isnt adjusting the seritone like I was told. If anyone has had any luck getting over this let me know. I see someone on this board talked about their adrenal gland. I am going to check this out. I am not a hypochondriac-I actually hate going to the dr and still do. If you have a comment dont tell me its all in my mind. I think it is in my nervous system or glands. I would file a lawsuit if I co | F | 45 | 2 weeks 180 1X D | 3/28/2010 | 3 | Seasonal Allergies | irritability, increased sensitivity to sun, seems to increase rosacea redness, harder to sleep, little grogginess, slight headache, less energy. | I did a search on Allegra and anger which brought me to this website. I have always noticed some physical and mental changes when I start taking this stuff. This year after two days I am really noticing that it is making me more irritable. I hope that it goes away after my body accepts it. I am also taking Nasonex with it. | M | 55 | 2 days not sure 1X D | 3/23/2010 | 3 | chronic sinusitis | Have had chronic sinusitis and first time allergies, cant take sudafed due to heart palpations, Dr. thought this would be great. Loved it at first, but too strong, cut them in half. Taking daily now for a month and have chronic dry cough, feels like my chest is tight, and throat is closing...just finally dawned on me to check for side effects of the allegra. too late, already took dose hour ago. will discontinue, call Dr. on Monday and in meantime use my netty pot, drown in my mucous I guess or go back to useless loratadine!!! THIS IS A FRIGHTENING FEELING | I WAS SO HOPEFUL ABOUT THIS MEDICATION AND SINGING IT'S PRAISES, MAYBE FOR NOW AND THEN USE...BUT FOR DAILY USE LONG TERM.....I ALSO REALLY WONDER WHEN OUR INSURANCE CARRIERS MANDATE US TO USE A 'GENERIC' IF THEY ARE RISKING OUR HEALTH...PERHAPS THE ORIGINAL ALLEGRA MIGHT BE BETTER | F | 57 | 6 months 180mg 1X D | 3/21/2010 | 4 | seasonal allergies | No side affects, I only take this drug on an as needed basis. | F | 58 | 5 years 180 1X O | 3/19/2010 | 3 | U R allergies | Might be just now figuring this out - have taken fexofen. for a LONG time for allergies. Strangely, it seems to help with arthritis in addtion to allergies (i.e. stopped it and horrible joint pain flared up) but also felt A LOT calmer when I was out of it (not taking it) this is a mystery! i cant even remember how long I have taken fex. b/c i used to take brand name. I am going to try NOT taking it and see if it is causing down mood and irritabliity...I will then try something at whole foods for allergies. | F | 51 | 6 years 180mg 1X D | 3/14/2010 | 4 | Chronic urticaria | Don't know. Maybe gastro-intestinal problem after long term use. | Have been taking the generic, fexo, for 2 years. It really helps my chronic urticarea, but now I'm having gastro-intestinal problems and I'm wondering if the fexo can be at fault. Just checking this website to see if anyone else has a similar experience. | F | 62 | 2 years 180 1X D | 2/24/2010 | 1 | cold/runny nose | My daughter was 13months when the dr prescribed this to her for the first time. I was told the side effects were very minimal. After my daughter received the third dose, within fifteen minutes, she was confused and disoriented. I attempted to get her to come around and she was unable to perform her normal tasks without a problem. After about 30 mins she went unresponsive. She was awake, but her body went limp and she couldn't focus or respond to me. I called 911 and took her to the hospital. She was unresponsive for about 5 mins. They contribtued it to either seizures or the medicine. We are waiting to hear the results of the EEG they did to determine if it was in fact a seizure. Even so, it may have been a medicine induced seizure. I do NOT recommend the use of this drug on ANY child. I know it was a horrible experience for me and my family and I don't wish that upon any one. Use caution!! | F | 1 | 2 days 30mg 2X D | 2/18/2010 | 4 | allergy relief | No adverse side effect. It has worked for me effectively | Allegra really treats my seasonal runny nose. I did not know that having seasonal runny nose could be the result of allergy. I bought 7 days trial supply from www.medsheaven.com. The next day,it casts my allergy. Few months after, my son had skin asthma as a result of allergy. I gave him Allegra, and instantly cure his allergy too. | F | 38 | 1 days | 1/23/2010 | 4 | Incessant dry cough, congestion | Major loss of appetite noticed immediately / really weird mood swings and apathetic or kind of dazed out mindset | Worked for my symptoms immediately - literally by end of day 1 I had recognizable improvement, and can definitely notice change on days I don't take it. Tried basically every generic cold & cough medicine out there, Mucinex, Sudaffed, etc, and they didn't really do much of anything. May cut dose in half to diminish side effects. | M | 22 | 1 months | 1/4/2010 | 2 | indoor allergies | Not really sure if it's from allergies or medication. Really could be either/or. Headache, neck pain, fatigue, blurred vision | I've been on it for 10 days. I asked someone how long it took this stuff to work and was told that if I had to ask that after 10 days, then it's not working. Have ENT appt. tomorrow, so I'll see how that goes. | F | 48 | 10 days | 12/28/2009 | 1 | Allergies | VERY STRONG nervousness, anxiety, difficulty sleeping, heart racing and palpitations | My doctor recommended I take allegra-D for allergies twice daily when I was diagnosed with asthma as an adult. I started taking it and it REALLY cleared up all my mucus, in my throat as well as in the sinus cavity area. However, the side effects with this medicine are not worth even the cleared sinuses. After the first dose I felt ok for about an hour, then when the medicine hit me I couldn't stop doing things (which was good as I am a college student, it made me feel like studying all the time), but then the dose wore off and I could tell it was like a letdown from the drug, I had to take another one after 12 hours or I would feel absurdly tired, like my heart/body had been working extra hard on the medication and I needed another dose or I would crash. After a day and a half I had to stop taking it. Do not recommend this!!! | F | 21 | 2 days | 12/20/2009 | 2 | fluid in my inner ear | Chest tightness and shortness of breath | I have been taking this medicine for about 10 years.I have had good results until recently I started to experience tightness in my chest. I am taking it with cozar ( blood pressure medication ) and prevacid. Do not know why this is occuring but it is very scary it can last up to 10 minutes about an hour after taking allegra D. I am done with this medicine for now ...... Previously I was taking seldane......need to hear if anyone else experienced the shortness of breath..... can't figure out if its the other meds in combination with the Allegra D..... | F | 54 | | 12/3/2009 | 1 | seasonal allergies | hives | my 3 yr old was on allegra for 2 days when he broke out in hives all over his body and they were climbing up to his throat. we had just taken him off zyrtec because it was making him unstable in his balance and he fell off a chair and got a concussion. everyone reacts differently to different medications. this one is not right for my son. | F | 28 | 2 days | 11/18/2009 | 2 | allergies | In the past I had no issues with Allegra - took for over 10 years and it worked really well - but now taking the generic daily (180 mg) it has caused anxiety, anxiousness and resulting sleep loss. I would awaken at 1 am and feel wide awake and unable to lie still. After about 2.5 to 3 hours, I would finally be able to rest again. Made work and daytime activities very difficult. Didn't realize generic meds were causing problem until I realized that when I had forgotten to take it I did not have the issues. Zyrtec does not work as well for me, but I will need to find an alternative. Perhaps halfing the dose will work. This is not hypochondria folks, put your vodoo sticks away. This is reality for people who may have suffered from allergies all their life as I have. Flonase is wonderful, as is patanase. My doctor prescribed both when I had a severe sinus infection in the spring (also added prednisone). I have found some success in using patanase and zyrtec in combination. And now am happ | F | 42 | 12 years | 11/11/2009 | 1 | seasonal allergy | I gave one pill yesterday to my daughter within 2-3 hours she started crying frantically saying she scared and she thinks something is going to happen ...3 hours later we realized she was having a panic attack .it was so intense, never did she behave this way! only this morning did i make the connection to the Medicine . | F | 7 | 1 days | 11/10/2009 | 1 | Alleriges | None | Allegra is worthless. I can't believe I actually paid money for it. I even felt bad for my health insurance company. If you are going to pay money for an antihistamine, get some Xyzal. | F | 37 | 45 days | 11/8/2009 | 3 | allergies | headache | I am AMAZED by these ridiculous hypochondriac-in-nature complaints -- allegra has so FEW side effects and I am VERY sensitive to ANY and ALL medications and supplements so if I was not adversely affected it's a good chance you won't be either. I have been on Zyrtec for a year and all that does is help me sleep at night so my doc is trying me on Allegra. Moderate headaches first two days but I am also using a neti pot so i think i am stirring up a LOT of gunk that's been lodged for years...if not must months! | F | 51 | 3 days | 10/20/2009 | 3 | seasonal allergies | not sure | I have taken allegra for years for severe seasonal allergies. I also take flonase nasal spray. Occasionally I have to add claritin and benadryl when things get really bad and of course there are problems with the benadryl - severe fogginess and feeling sleepy. After suffering terrible colds/sinus infections every winter, my doctor urged me to take my allergy medication year round because colds stimulate an allergic response in allergy sufferers. I also have problems with anxiety and depression and take medication for that. I am surprised to read so many comments describing anxiety as a side effect of this drug. Not sure if mine is exacerbated by this drug. What's a person to do who can't even go into their own garage for fear of setting off an allergy attack? I can't survice without relief from my allergy meds. But I'm starting to wonder of its impact on my moods. In fact, every drug I've looked up on this sight seems to cause anxiety in some people. What's the deal? | F | 44 | 5 years | 10/15/2009 | 5 | Hay Fever/Seasonal Allergies | None. Sometimes I double the dose and take 2 at once. No problems. Ever. | Wow, I'm reading about all of these people with alleged side effects from Allegra... wow, what a bunch of mentally ill hypochondriacs !!! I've taken this medication 2 years on and off and it is by far the best one out there. When I start the medication, I take two tablets (no side effects) and just take one every 12 hours and it is a life-changing lifesaver. Thanks Allegra! | M | 35 | 2 years | 10/7/2009 | 5 | ALLERGIES | M | 68 | 5 years | 10/6/2009 | 1 | severe seasonal allergies | So glad I found this site! I to was perfectly fine till I started taking allegra. I experienced weakness,insomnia,problems with my stomach,confusion,depression,mood swings,extreme tiredness, heart palpatations, tremors,leg pain. I still do not feel quite myself. I would suffer with all the symptoms of allergies than face what I have over the last month. Wish I would of found this site before I started taking the allegra. | If taking this drug and you experience any unusual symptoms "STOP TAKING THIS DRUG" This has been a nightmare! | F | 45 | 1 months | 9/28/2009 | 5 | allergies | none | I have been completely satisfied with allegra. I have noticed a significant reduction in my allergy symptoms as well as rash breakouts. I take Allegra twice daily, and need that dosage in order to keep my symptoms under control. I am very pleased! | F | 32 | 5 years | 9/27/2009 | 1 | hives | twitching of the eye, anxious | My 7 year old son was prescribed allegra for hives. I gave him 5ml 2x a day for 2 weeks. I will never give him this again. The hives were less, but the twitching of the eye became worse. My doctor told me to go see a neurologist now to rule out seizures. What is going on? | M | 7 | 2 weeks | 9/24/2009 | 3 | allergies | Irritability and shortness of breath. | Took away the closed-up, itchy feeling in my throat from allergies, but I definately don't like the side effects. Took it yesterday and was very irritated with my children that evening for no apparent reason, and am experiencing shortness of breath today. | F | 45 | 1 days | 9/23/2009 | 1 | allergies/eczema | extreme fits of anger, no appetite, tiredness, hyper, changes in personality | My 2 year old sons personality changed 100%. He had fits of anger where he would tell me "I don't want to be angry" but couldn't stop. I was blaming it on the "terrible twos" until I forgot to give it to him for 2 days and his personality went back to normal!!! I would NOT recommend this for children. | M | 2 | 3 months | 9/18/2009 | 1 | Seasonal Allergies | stomach pain, anxiety, insomnia, depression, lack of energy, some constipation, and very emotional. | My 10 year old son was put on this medicine for allergies. After taking it for about 10 days, he started having stomach pain, especially in the evening. He also started experiencing anxiety, couldn't fall asleep, depression, lack of energy, some constipation, and was very emotional. We were up until all hours of the night for several weeks. When I finally googled Allegra, I saw that others were having the same problems!! We took him off immediately, and the emotional side effects started gong away. It took another week for his stomach to be back to normal and he is finally sleeping again. Why is the medical community still prescribing this medication??? | M | 10 | 3 weeks | 9/18/2009 | 1 | Allergies | Inability to sleep. "Racing thoughts," OCD-ish thoughts. | I am a 39 year old Female. I suffer from mild OCD, but found this drug increased my obsessive-thinking tenfold. I could not let things go, my thoughts raced, I found myself reliving memories over and over and not being able to put them aside. I have taken this before without such side effects, but tonights experience has tauhgt me not to take it again. I hope I get some sleep. | F | 39 | 1 days | 9/10/2009 | 3 | runny nose | nervousness, shakiness, inability to concentrate and serious loss of appetite | works for allergies and its symptoms but the side effects are strong | F | 22 | 3 weeks | 9/4/2009 | 1 | Congestion, Post Nasal Drip | Nevousness, very jittery, shaking of arms and legs. | Started taking and over a 3 week period I became more and more nervous, jittery, skaking all over. Made me feel very bad and anxious. | M | 52 | 3 weeks | 8/15/2009 | 5 | Allergies | None. | This drug has been a lifesaver for me. | F | 35 | 2 years | 8/8/2009 | 4 | Allergies | None | Doesn't work as well as some of the other medications I've tried, but it does provide some relief and it's the only one that hasn't given me unbearable psychological side effects (or really any side effects to speak of). | M | 32 | 6 months | 8/8/2009 | 4 | allergies/sinus&ear problems | mental confusion,racing heart, extreme fatigue, irratability, can not concentrate on more than one thing at a time or stay focused for long | I am glad I looked at this site, and have seen that so many others are feeling the same way. I was taking benadryl otc, but it would literally knock me out about 30 min after taking, so I could only take before bed, and that did not help me get through the day. I think I will give it the rest of the week (just started three days ago) and see if I "normalize". Other than that, it looks like I need to go back on the benedryl, and sleep my day away... | F | 32 | 3 days | 7/8/2009 | 1 | Sinus Infection | When taking this I went through a great load of deppression and bad thoughts. It ruined my weak and scared me. Never taking it again! | M | 16 | 2 days | 7/8/2009 | 2 | Severe Allergies | Heart palpitations, in a daze, forgetful, don't have a clear head, confusion | I used to take Allegra years ago and don't recall any issues with the med, I'm beginning to wonder if they haven't changed up the ingredients, because I feel like crap, have headaches I can't knock! I feel like I'm in some kind on uphorea! Does anyone know if severe allergies trigger migraines? | F | 31 | 4 times | 7/6/2009 | 5 | hives | none | it has been a lifesaver for me. for several years, i had hives all over my back, legs and arms almost every night. since i've been on the allegra, no more hives. additionally, i believe it has helped my allergy-related sinusitis, as i've had no sinus infection since i began taking it, and i typically get 2-3 per year. a miracle drug for me. | F | 33 | 6 months | 6/24/2009 | 4 | allergies - runny nose, sneezing | Dizzy spells. I forget about this every year and then take a bit to figure it out again. Very annoying. | Doesn't quite remain effective a full 24 hours. Still the best thing I've tried in terms of relieving the symptoms and letting me remain functional. I only take it as needed, but certain times of year that's almost daily. Claritin made me feel like I'd been stomped and smushed, and about anything else makes me sleepy. | F | 36 | 6 years | 6/21/2009 | 1 | Sinus issues | I have never felt worse. Panick stricken, depressed, irritable,severe headaches. By the 5th day I thought my head was going to explode. I had no idea that this was coming from the meds I really thought I was losing it. I then equated it to Allegra. I was also taken Nasonex. I will deal with the sinus issues and NEVER take either again. | F | 37 | 5 days | 6/21/2009 | 1 | Chronic sinusitis | Dizzy spell, couldnt drive, heavy drowsiness | Horrible side effects. could not drive and the jug handles were the worst. Had to somehow manage to go to the nearest safe place to park and had to call a friend for a ride. After stopping couldnt get back to normal for almost three days. | F | 29 | 3 times | 6/19/2009 | 1 | itchy nose | anger, no appetite, tiredness, hyper, changes in personality | My 3 year old daughters personality changed 100%. I would NOT recommend this for children. | F | 3 | 5 days | 6/15/2009 | 3 | Allergic Rhinitis | EXTREME Heart Palpitations (thought I was having heart attack), irregular heart beat, anxiety, headache, stiff neck | Allegra cleared up my allergies after 2 days of taking 60 mg tablets. I took Allegra for one week and felt like I was having a heart attack one morning (I was 22 years old). I went to see my doctor and he said that my heart was perfectly fine. Every doctor in his office told me that Allegra does not cause heart palpitations. I stopped taking Allegra for one year and have not had a single heart palpitation since. I recently began taking Allegra again and have had heart palpitations on several different occasions, including one palpitation episode that woke me up in the middle of the night. Two different doctors (one is an allergy specialist) have since told me that Allegra does not cause heart palpitations or irregular heart rates. I beg to differ. | F | 23 | | 6/13/2009 | 4 | Allergies | Occasional heart palpitations and a feeling that I'm a little out of breath. But it's worth it!!!! The alternative it out of control allergies. No other non-drowsy medicine has been able to control my allergies like allegra. Benadryl works too but knocks me out for at least four hours. At least I am able to function on this medication. | F | 28 | 10 days | 6/11/2009 | 4 | Allergies | Mild headaches. Tender neck glands. | Zyrtec and Claritin just don't cut it anymore. I started Allegra-D and it works like magic. No allergy symptoms whatsoever! My only complaint is I'm getting mild headaches and the sides of my neck are kind of sore. | M | 35 | 3 days | 6/10/2009 | 2 | Hives , now Foliculitus | I only took it for a few days, as I was on Prednisone and Pepcid to SEVERE HIVES....that cleared up, went to Dr yesterday with breakout on face, neck and upper back, Dr. said Folliculitus...put be back on Allegra and Pepcid..took pills before bed....WRONG THING TO DO!!! I had heart palpitations, made me dizzy and weird in my head, was tired but had a hard time sleeping, felt like things were crawling on me...I am done with it. | While I do see some improvment, albeit minor in my skin this morning, it is not worth taking the Allegra, I don't like the feeling in my head at all. This was only one dose this time...with hives took it for about 5 days and was not functioning, and crying and BLAH. I have always had a problem with antihystimines..this is no better. | F | 48 | 1 days | 6/3/2009 | 5 | I started taking allegra 5 days ago and it has helped me so much. I have severe allergies, eyes, nose, allergic asthma. I have used clariton and zyrtec everyday(not at the same time) and tried allegra to see if it was better. Well, it is for me. Way better. I can't believe I have found something that actually dries my nose and clears it and especially clears my eyes which usually swell because of allergies. This stuff is awesome. I am so glad I tried it and highly recommend it. I have had NO negative side effects at all from it. It is a miracle drug for me. I am taking regular Allegra (generic) not Allegra D, that is what is so amazing about the unstuffy, non runny nose. | F | 48 | 5 days | 5/28/2009 | 2 | Chronic Sinusitis | Upset stomach, gassy, diarrhea, perhaps some of the other described side effects like lack of focus, difficulty urinating. Hives too, but I think those were from allergens and not the Allegra generic tab. I began to take only 1/2 a tab in addition to my nightly zyrtec. I was always loggy and tired in the morning, into the early afternoon. | I went off all drugs after I saw a new allergist who did new food testing to find I was allergic to wheat, yeast, sesame, potatoes, bananas, tuna, white grapes (wine), and peanuts. I felt much, much better, more energy, focus and less stomach issues. I now have to take another antihistamine, but only take 1/2 of a Zyzal at bedtime. More than a 1/2 and I'm a zombie in the A.M. If I'm desperate and really allergic or if I've cheated badly on my diet, I take 1/2 of a Loratadine. It's not great but is keeping the sinusitis in check. | F | 55 | 6 months | 5/26/2009 | 1 | allergies | Dull persistent headache between the eyebrows, neck stiffness | I have only been on it for 4 days but after wondering what was wrong with me and googling for side effects, I find that many people experience these symptoms -- I have stopped the allegra today and am back on Clarinex and 3 tylenol gel caps!! | F | 46 | 4 days | 5/26/2009 | 3 | seasonal allergies | I've been having gosh awful headaches and neck pains. Had figured those were just due to the bad arthritis in my neck and back, but this is much worse. Figured my irritability was just because of the headaches and neck and back pain, but maybe not. It definitely does leave me a bit foggy, mentally (not nearly as bad as Zyrtec, benadryl, etc.). It does seem to make tinitis a bit worse. Have had to take antihistamines all my life and this one, especially the old capsule Brand form, seemed the best of the evils. Maybe my tolerance for drugs is decreasing. | Except for the heart arrhythmias (etc.) with Seldane (precurser to Allegra), it was the best antihisamine but allegra works fairly well on my hayfever, etc. It lets me go outside--a good thing!! Claritin causes VERY bad tinitus in me as well as general "yucky" feeling. Zyrtec really zonks me out. Good old chlorpheniramine works fairly well but leaves me a bit "dopey". Recently haven't been able to find an effective antihistamine that has no nasty side effects. | F | 63 | 10 years | 5/25/2009 | 1 | Seasonal Allergies | Extreme depression, erratic and unpredictable mood changes, "weird" thoughts, anger, some fatigue. | I was taking name-brand Allegra and the mental side effects were simply unbearable. Looking over the other comments, it seems the generic substitutes can be as bad or even worse. My experience with this stuff was a nightmare. | M | 23 | 2 months | 5/23/2009 | 1 | seasonal allergies | depression, anxiety, not myself | Have taken Allegra (brand name) in past with no issues - received generic this year. Side effects included feeling zonked out - (almost had an auto accident) enjoyment of food and taste affected - thought I was just getting used to drug. Decided to quit and go back to sneezing 40-50 times a day until end of allergy season. Better feeling myself though. | M | 34 | 20 days | 5/21/2009 | 3 | had poison oak or something similar | taking the generic. the first week it was okay. second week i have terrible chest pain, and upper intestinal pain.not sure what it was, then i found this site and noted others experienced the same. | it has someone contained the poison oak but after two weeks i don't want to continue, if this is the cause of the chest pain. | M | 59 | 14 days | 5/20/2009 | 3 | Allergic Rhinitis | Within a day of taking it, I felt as if the facial area above the mouth was all plugged up aka same as facial tenseness/tightness. Constant feeling of tizzy, and as the day progresses it turns into extreme fatigue and tiredness. Feeling jittery all the time. | I'm taking the generic brand of Allegra and not Allegra-D. It's helpful with the allergy related symptoms but it surely does come with v.significant side effects of it's own....am considering to try Benadryl instead. Can't continue with the originally prescribed 30 day supply. | F | 33 | 4 days | 5/10/2009 | 3 | allergies | not sure | According to my mom and girlfriend, over the past few months I have been in my own little world. I've been taking the fexofenadine 180mg for over a year only during spring and fall. Apparently though I am having mood swings and have been very detached. I'm wondering if other commenters aren't just a bit paranoid about their "side effects". I'm an EMT and I blame any detachment to job related stress. Would love any opinions though. Email.. | M | 19 | 1 years | 5/3/2009 | 1 | allergies | anger, loss of appetite, extreme tiredness, very hyper and extreme changes in personality. | My 2 1/2 yr old son took this medicine for 4 days and it changed his personality drastically. All the changes were negative. He was aggressive, defiant, outbursts of crying. Complete opposite of his normal personality. I would not recommend this for a child. | M | 2 | 4 days | 5/3/2009 | 1 | seasonal allergies | none - didn't have any effect at all | no side effects...actually no effect at all. Had been taking OTC generic Claritin for several years & thought it was not working as well as previously so talked to doc about something better. Put me on Allegra. Took it for 3 days - had the worst allergy symptoms I've had in years...nasal drainage non-stop, sneezing, itchy eyes, etc. If I didn't know better, I'd say the Allegra CAUSED the symptoms. So I went back to fake Claritin - it doesn't completely clear me up, but does a far better job that prescription Allegra. | F | 52 | 3 days | 4/29/2009 | 1 | Seasonal Allergies / Asthma | Rapid Heart Beating, Chest Tightness, Anxiety/Depression, Aggression, Back Aches, Neck Aches, Leg/Feet spasms and numbness, Night Sweats, Dry mouth, Dizzy spells (like when you get really hungry) | I blatantly asked both my Doctor and my allergist if Allegra could cause some of the symptoms above especially the chest tightness and they said NO. I am SOOOOOO Glad I found this website. I am quickly losing faith in the medical community. | M | 32 | 1 years | 4/28/2009 | 1 | Allergies | I thought I was the only on feeling this way until I found this website. I have been on Allegra for about a month and have suffered extreme anxiety, tension, confusion, dizziness, inner ear problems, crying, irritabiity, etc Now that I have seen everyone elses comments I am no longer taking this drug! | F | 24 | 4 weeks | 4/23/2009 | 1 | allergies | At first Allegra(generic) worked well, in about eight days I was suffering terrible anxiety. called my pharmacy and they said it shouldn't cause that side effect. Sadly, something that helps allergies, but not worth suffering daily with anxiety. Very pleased I found this site. All other links deny generic Allegra could cause anxiety. Thanks for all these postings, I thought I was the only person with this side effect. | I will never take Allegra again, will ask doctor for something else to assist with allergies. There is no mention on the printed information that states anxiety may be a side effect. Maker of this drug should include the all the real side effects. | F | 64 | 8 days | 4/22/2009 | 1 | seasonal allergies | Horrible anxiety, depression, crying, neck tension, heart palpitations. I have been under stress lately and thought I was actually starting to have nervous breakdown. Just wanted to stay in bed in a dark room, this has been awful. My husband and mother were so worried. Was planning on calling my doctor to see if I needed an anti depressant. Please do not take this drug. Why is this company allowing this drug to be taken? Seldane was taken off the market and Allegra is a metabolite of Seldane. Stay away! All this after just one dose!!!!!! | F | 42 | 1 days | 4/19/2009 | 1 | Pollen allergies | Extreme anxiety, chest tightness, stomach tied in knots, tense neck and face muscles. | I was taking generic Allegra 180 (NOT Allegra-D) for allergies, and after a couple of weeks started experiencing horrible black moods, debilitating anxiety and stomach pains. I felt like I was choked up most of the time, and my neck and head muscles were very tense. It was a bad, bad experience and I felt like I was losing my mind. I don't even know why it occurred to me that it might be the Allegra, but once it did I checked out this board and was very relieved to find I wasn't the only one. This stuff is nasty, and these side effects are never mentioned in the literature that comes with the prescription. | F | 52 | 3 weeks | 4/10/2009 | 3 | Seasonal Allergies | About a day after starting the new prescription (generic allegra-fexofenadine) food, lotions, basically anything either has a chemical taste or smell to it. Anyone else have this? | Will this go away. My allergy symptoms are completely gone, but I am not really enjoying the other part! | F | 34 | 8 days | 4/7/2009 | 1 | Chronic Hives | Severe Leg Cramps and Muscle Weakness | If anyone has experienced this problem, how long before the leg cramps went away after stopping the drug. I would rather deal with the hives. These cramps are horrid. | F | 59 | 10 days | 4/6/2009 | 1 | seasonal allergies | aggression, irritability, mood swings, stomach cramps | Thank God I have my little boy back and thank you for this comment board. I researched all the side effects before giving Allegra to my son and none of his symtoms were mentioned. So I just thought that it was the terrible two's. The Allegra took away his allergies but it took away his personality with it! He is my little angel again and is now talking in sentences! | M | 2 | 9 months | 4/1/2009 | 1 | Seasonal Allergies | Anxiety, Depression, Irritability, Anger, Night Sweats and Grinding. | For someone like me who struggles with anxiety disorders and irritability it was a bad choice. It did improve allergy symptoms about 50%, but I might as well just take OTC stuff and avoid the side effects that almost cost me my job and family. Don't take if you have or have ever had. GAD, depression, panic, mood, irritability issues. Otherwise, Good luck. 8-) | M | 28 | 15 days | 3/30/2009 | 1 | environmental and pet allergies | exhausted, bloated, irrational, paranoid, depressed, crying, feeling of hopelessness, hungry all the time | Symptoms are getting progressively worse. overreacting to my kids today again, crying, hiding in my room. I used to be a positive, upbeat, high energy person. all i want to do is sleep and be left alone. I'm not taking this anymore. I'll take being in a bubble over this. | F | 38 | 6 days | 3/27/2009 | 1 | intense itching | tight chest, heart palpatations, really tired, light headed. | Oh My God I am glad I found this site, this stuff sucks I feel terrible and I couldn't figure out what was wrong now I know. | M | 45 | 1 weeks | 3/17/2009 | 1 | urticaria | Can not stop eating. Back ache, incredibly snappy and intolerant, dry mouth, sore throat. Very tired | Thank god I found this site, I knew something was odd which is why I sat down with my 2 litre bottle of water. The tablets are going in the bin! | F | 30 | 2 days | 3/13/2009 | 4 | Chronic Autoimmune Hives | Anxiety, Depression, Back Pain, Heart Palpitations | I've been on and off Allegra 180 mg. since 8/04 for chronic hives, which were just diagnosed as autoimmune. The medication helps immensely to reduce the histamine levels in my system and control flares. Having said that, my experience with the generic vs. brand drug has been HORRIBLE. It was only when my Dr. switched me to the generic that I began experiencing back pain, occasional heart palpitations, and overwhelming anxiety and depression. All generics are NOT created equal, and I'm fortunate to have an allergist who's understanding and acknowledged my symptoms as genuine. He switched me back to the brand and even called my HMO and encouraged them to cut me a break on the price, which they did. I will NEVER go back to the generic again, and while it may have the same efficacy, as others have mentioned, it also carries terrible side effects that I did not encounter on the brand name. I still think that nothing works better than Benadryl, but for those of us who work and need to | F | 41 | 4.5 years | 3/12/2009 | 1 | sinus drainage | I started on allegra generic about 3 weeks ago. I had been taking Xyzal and loved it, but I was trying to save a few bucks. I'm also currently on Pristiq (anti anxiety/anti depressant) and Focalin for my ADD. I am recovering from a 2 year nightmare with depression and anxiety and HAD been feeling great. About a week after starting the Allegra, my anxiety returned, I started getting horrible headaches, and the night sweats have been so bad I was planning on calling my doctor to get on some estrogen (I'm 50). I had also been taking Nexium for acid reflux, but switched to a generic Protonix at the same time I started taking the Allegra generic. My heartburn is horrible - I had thought it was originally the protonix, but it's not. I have been anxious, not sleeping, irritable with my family, and basically a mess for 2 weeks. I realized today that I had felt better yesterday, but forgot to take the allegra so I got on the web and found this site...thank god I did...I am so mad that t | DO NOT TAKE GENERIC ALLEGRA | F | 50 | 3 weeks | 3/11/2009 | 2 | Dry eyes and throat. Backache. | I wanted the dry eyes to reduce the symptoms of corneal dystrophe (Fuch's endothelial corneal dystrophe.) Allegra is somewhat helpful in this respect. But the constant backache was unacceptable. Note: I only found this was caused by the Allegra by browsing in the Physician's Desk Reference at the library. This side effect was not on the pharmacy handout. I thought Allegra might be doing something weird because it gives the same instructions as Cipro regarding fruit juices and antacids, and Cipro did a real job on me in 2004. The backache went away over a period of several days after stopping the Allegra. However, my urine stills smells peculiar and I wonder if the Allegra was causing the backache via kidney damage. Incidentally, one of the many dispicable Cipro side effects came back slightly while I was on the Allegra: pain in Achilles' tendon. | M | 65 | 3 weeks | 3/4/2009 | 1 | seasonal allergies | This is my second time around to report on this stuff. I took this stuff 6 months ago. I am still not right. I still can't exercise because my heart rate won't come down if I get it up too high. I have severe acid reflux from allegra that caused chest pains. I still have massive anxiety like attacks that my new functional medicine doc says is caused from my now screwed up adrenal glands. I still get tackycardia, uncontollable shakes, cold and hot feeling and feeling light headed and like I will pass out.I have an inner ear problem now that caused balance issues. All from this medicine. I used to work out 2 hours a day. I was in great shape when I went on this med. My original doctor told me " it screwed up my whole system." Do not take this medicine! I thought it would kill me, I'm glad it didn't. I just hope I don't have to suffer like this for the rest of my life. | This drug is dangerous. I was very healthy and when I took this drug it ruined my life. They kept saying wait until it gets out of your system, its been 6 months I am still a mess. | F | 28 | 13 days | 2/24/2009 | 5 | allergies | dizziness and feeling medicated. Twice when eating (Jalapeno) Mexican peppers (which I love but always aggravated my allergies) I felt noticeably weak and cold and sleepy. I don't eat these anymore. I might try them again later just to make sure of the causal relationship. | I have read some people saying that they experienced depression. I feel the opposite that it alleviated my "depression." (I feel in a better mood.) And I am more active and have more energy. Before I would fatigue easily and felt tired most of the time. I feel much better and my allergies (which were chronic) are much improved. I feel Allegra gave me my life back. | M | 50 | 3 weeks | 2/22/2009 | 1 | for nasal stuffiness and sneezing | My heart is pounding , I am experiencing tachycardia, restlessness, EXTREME anxiety and worst insomnia. | I took this drug to relieved my nasal congestion, runny nose , frequent sneezing and headache. However the result are extremely bad, right now I am suffering due to lack of sleep, it's 2am, I am wide awake with my heart pounding right out in my chest.. I feel horrible and so wasted . | F | 26 | 2 days | 2/19/2009 | 5 | Environmental allergies | None after a little over a week. | I've had no problems from the regular Allegra (am currently taking the generic). I took Allegra-D for a few days only, and it made me extremely wired (I went from my usual steady and calm self to feeling like Tigger. No joke). That was probably the pseudephrine- if I take a 12 hour Sudafed along with the Allegra I feel a little wired, but not nearly as bad. It's less of a distraction than being congested. I don't feel that way when I take the Allegra by itself. Before I started taking it, I was having constant sinus congestion, and frequent asthma symptoms (mainly chest tightness/pressure and an awful sounding cough), which I had not had with my allergies previously. Several members of my family have adult-onset asthma, and that's what I thought it was. Since I've been taking the Allegra, my chest hasn't felt tight at all, and except for first thing in the morning, my cough is gone. My sinuses are MUCH better too. Has definitely worked for me. | F | 30 | 10 days | 2/17/2009 | 1 | Severe Allergies & chronic snoring | I started taking Allegra generic 10 days ago to alleviate the constant stuffed head and snoring as a result. By day 8, I found myself irritable, irrational and emotionally depleted finally resulting in screaming at my husband! The only thing that has changed is taking the allegra, so I did some reading on line and luckily, found this blog. It's very obvious to me, particularly after reading so many reports on this blog, depression can be a side effect of Allegra. I stopped taking it and it's been 48 hours since my last dose. I'm beginning to feel better. I'll take the snoring and sniffling over depression any day! | F | 46 | 10 days | 2/15/2009 | 4 | congestion, seasonal allergies | Depression, insomnia, dry mouth, difficulty urinating | Overall this is a good medication and works well for me. Two of the problems I mentioned are coming from the pseudoephedrine (depression and insomnia). However, the depression seems to have decreased over time (that or I'm just getting used to the "new" me). | M | 58 | 2 years | 2/13/2009 |
