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.

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.....

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

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 Email
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 Email
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..

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 Email
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 Email
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 Email
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 Email
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 Email
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.

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
1	Allergies	extreme headaches, dizziness, nausea, motion sickness	I started taking allegra to alleviate a severe extended allergy attack. I was already so sick and on so many medicines that I didn't realize that the allegra was causing my new symptoms. I took it for 6+ months. The entire time, I suffered from constant migraines, dizziness, nausea, and motion sickness (I have never otherwise had migraines or motion sickness in my life). During this time, I was probably sleeping 12 hours a day. I finally connected the dots that the allegra was causing my symptoms when I took a plane ride and thought my brain might explode. Stopped taking the allegra and was 100% better within 2-3 days.	F	29	6 months		2/2/2009
5	Allergies	No side effects, this drug is great for my terrible allergies.	A lot of people are posting ANXIETY as a side effect here. Allegra does not cause anxiety, Allegra-D causes anxiety because of the Pseudoephedrine in it.	M	29	2 years		2/1/2009
4	Sinus infections/Allergies	It is hard for me to know if the moodiness I've attributed to PMS and the insomnia I have are due to this or not because I can't get off it. If at any time I try to stop taking it, within 1 day I start itching. I start itching around my ankles and it works it's way up and eventually I'm itching like a crazy person. I have no choice but to take again (or enter a psych ward). I used to take Zyrtec and had itching when stopping it, but it was minor and didn't last more than a day. The most I've made it is 3 days without taking this stuff before I gave up. I'd love to know if anyone else has this problem.	It has worked for my allergies and I haven't gotten a sinus infection in over a year.	F	40	5 years		1/19/2009 Email
3	sinuses, allergies, ear infections	menstrual type cramps	I have been on Allegra-D since I was 16 and I loved it. It cured my chronic sinus infections and ear infections with no side effects. My insurance recently changed and would not cover Allegra-D anymore. So I am now taking Allegra, the generic version. I started taking in on Monday and today is Wednesday and I cannot sleep I am having such horrible abdominal cramps. I read the side effects in the information I got from my pharmacist and it mentioned menstrual type cramps. Maybe someone has had this problem with the generic and not the name brand? I am calling my pharmacist tomorrow morning.	F	24	3 days		1/15/2009
3	Hives, severe itching	weight gain, sore joints, bloating, decreased sex drive	I started taking generic Allegra this summer for sever chronic hives. The hives started for unknown reasons in March '08. I was taking Claritin until I finally got in to see an allergist in June. I have to take two 180mg pills (one in the am and one in the pm) in order to make it through the days and nights. The side effects are slowly getting worse--weight gain, back pain, joint pain. I can't stand the hives either--they cover every inch of my body and it's unbearable. I did notice the pill bottle does say "drink with plenty of water." Will try to up my water intake to see if that has an impact. Otherwise, I may try claritin again and see if the side effects go away.	F	32	7 months		1/2/2009
4	chronic allergies	none I take 80mg. only prn-not on a regular basis. Do not and have never taken the generic	I am just wondering after reading so many of the comments how many of these people are taking the generic as oppossed to the name brand. I noted that one person mentioned that the generic gave her side effects but the name brand did not	F	73	4 years		12/29/2008
5	chronic bronchitis	Allegra controls my allergy-triggered congestion before it escalates into bronchitis. I have no drowsiness and notice no negative side effects at 60 mg dosage.	Allegra is one of the few drugs that work for me... unlike Allegra-D, (which elevates blood pressure and causes restlessness or "the jitters"), it has no down-side. I take it almost year-round 60 mg every 12 hours as needed. IT REALLY HELPS ME WHEN TAKEN AT NIGHT. Have tried the once a day higher dosage but it caused sleeplessness. If I don't take allegra during allergy season, I will get bronchitis/pneumonia.	F	45	5 years		12/27/2008
3	fluid behind eardrum	constipation, and the entire Allegra pill came out with my bowel movements, the pill itself did not dissolve at all.	these side effects made me wonder if it's the Allegra doing it's job or if I just got better.(I no longer have fluid behind my eardrum)	M	18	1 months		12/27/2008 Email
1	Sinus infection	EXTREME anxiety, depression, sleeplessness, heart beating out of my chest. (P.S. I have NEVER experienced any anxiety or depression in my lifetime before this medication. I now have a different perspective of what people who are depressed or suffering from anxiety must have to deal with.)	The Allegra D worked extremely well for relieving the nasal congestion, but within 2 weeks I was not sure if I would live. This drug should be banned. My physician only prescribed 2 weeks worth and he stated that Allegra D should not be taken on a regular basis. It's prescribed use is for a temporary relief such as congestion from a cold, whereas standard Allegra can be taken on a regular basis.	M	46	2 weeks		12/19/2008
1	allergies	My son is 6years old. At the beginning of the month we started him on allegra, due to severe allergies. With in a matter of days his personality changed tremendously. He has always been a high spirited little boy, but rarely got in trouble at school. Within the last two weeks since starting Allegra he has been acting out in class, and acting very strange and silly. the only changes in his life, has been the starting of Allegra. I can say it worked to clear up his allergy symptoms, but it drastically changed his personality. I took him off this weekend and it was the best thing I have ever done.		M	6	3 weeks		11/17/2008
1	Chronic Sinusitis	Craziness, Headaches, Dizzy all the time, Nightsweats and major sleeplessness nights.	This durg SUCKS! Who ever approved this to go on the market should be put in jail. As I read through the comments from other poor souls taking this shit I find everyone is saying the samething. It almost destroyed my life. I HATE Allega-D and the company that makes it. I see a law suite coming!	M	48	7 days		11/14/2008
2	Allergies	Extreme anxiety, panic attacks, hopelessness, depression, crying, general paranoia and feeling on the brink of craziness.	I wish I had found this site earlier - I have had the most horrible 7 months (emotionally) while taking this drug - the only time I felt like "myself" was when I was not taking it, but since it is an allergy drug I never made the connection. It works wonderfully to deal with allergies, but it seems to amplify all sorts of emotions to a dangerous level (for some people). Wow, after seeing other similar reviews, I am stopping IMMEDIATELY.	M	29	7 months		11/1/2008
3	intense itching	I had intense itching on my arms, legs, back and buttox. I was diagnosed with a skin condition called dermatographia(if I scratch myself it turns into a welt that takes a day to go away). An allergist put me on a daily dose of Allegra(I take the generic) in the morning and Zyrtec at bedtime. I have no itching anymore which is amazing but I am gaining a lot of weight! I am only taking a children's dose of liquid Zyrtec at night because an adult dose made me so sleepy I slept the entire next day!		F	57	5 months		10/27/2008
1	seasonal allergies	Horrible abdominal cramping not affected by warm compresses or pain meds, extreme bloating, constipation, light colored bowel movements, headache, nausea, and insomnia	I don't take any medications, am healthy and knew something was terribly wrong. Coworker told me it was the allegra, stopped taking it and my symptoms are easing off gradually, but am still experiencing them.	M	32	5 days		10/8/2008
1	allergy, frequent sinus infection	depression, despair, crying all the time, nightmares, anxiety, mild suicidal ideation, poor concentration, confusion, felt like I was zombie, decreased reaction time, paranoid thoughts, felt like I was loosing my mind, irritability, borderline psychosis	I took this med for less than a week and I thought I was falling apart. Started med on Friday and by tuesday I could barely function. The symptoms were so severe and began so fast I new something was majorly wrong. I thought a city bus might start talking to me and was staring off in space for hours. My mother asked had I began any new meds lately, I said only this allergy med. Surely that wouldn't be causing all of this. I found this web site and stopped the med at once. i'm glad it only took 5 days. I'm normally a very happy and motivated person and I was beginning to think of suicide. Scary.	F		5 days		9/25/2008
5	exercise induced urticaria	none	i have exercise induced urticaria (i break out into big red itchy hives when i exercise)...i have NO other allergies...allegra keeps me from breaking out...so i take it EVERY morning...now...if i forget to take it in the morning and even go out for a nice leisurely walk - i will start breaking out into hives...prior to being prescribed allegra by my allergist, i wasnt even able to go for a walk for more than a couple minutes before i would break out into hives...as you can imagine, this kept me inactive for the most part...however, allegra has given me my life back - i love it!	F	28	2 years		9/24/2008
1	Pollen Allergy	Insanity, confusion, anxiety, irritable, aches, tired, sleeplessness, nightmares, increased heart rate, hot flash.	Wife bought it to try it out. I had no idea what was happening to me. This drug practically drove me insane. I thought I would do a search (since it is the only drug I am taking) and found this site. I just stopped two days ago and I am feeling better already.	M	34	40 days		9/16/2008

3	Sinus, allergies	Depression and irritability.	I was getting irritated easily, and didn't want to be around my wife and son, and I got really drowsy so went to sleep grouchy. When I woke up, I thought something was weird with the thoughts going through my head, and related it to the medicine. But it did help my allergies, so I don't know what to do now.	M	28	5 days		9/14/2008
1	severe seasonal allergies	Heart palpitations, racing heart beat, chest tightness, chest pain, and dizziness, decreased sex drive.	I took the allegra D. I will never take it again. I ended up in the hospital overnight! I had a hot and cold feeling come over me. On the inside I was hot but my skin was freezing and clammy. I felt like I was going to pass out and I had tightness in my chest and chest pains. my resting heart rate was between 100 and 120 when it is normally in the 60's. It was terrifying. I have been off it since sunday night today is friday and I am still having some effects. but they are lessening as the drug gets out of my system. This stuff can't be good for you.

3	seasonal allegies	I felt anxious, irritable, restless, and occasional chest tightenting. I have not experienced this before, but have not taken it as long. I stopped taking it and felt better.		M	34	8 days		9/7/2008
4		None at all, no perceived changes.	If I miss the time dosage by a minute and then take it, it won't work or ever begin to work that day. So you should make sure to get your doses in on time because once your body gets all charged up and allergic it can't step in and stop it. Also, for moving dusty boxes in the basement and such, this medicine is not strong enough. I will preemptively take a sudafed as well for such activities.	F	21	8 months		9/6/2008
5	Year round allergies	No side effects on the name brand, Allegra 180 (not the Allegra-D). I will not ever take the generic of Allegra again. Have taken it twice this year, ended up with sinus infections, headaches, constant sneezing, horrible drainage, all things I never experience while taking the name brand.	I feel great on the name brand, no problems. I take one in the morning and it lasts all day. I can work inside or out without any sneezing or other allergy symptoms. We had to fight with the insurance company to allow me to take the name brand at our copay price. I will not ever take the generic of Allegra again. Took it for a total of 3 1/2 months this year, ended up with sinus infections, headaches, constant sneezing, horrible drainage, all things I never experience while taking the name brand. Stick with the name brand on this drug.	F	53	5 years		8/29/2008

2	Allergies hay Fever	Since I started taking Allegra about a month ago to treat hay fever, it seems that my nose is runnier now than before! I've also experienced chest tightness and shortness of breath (very unusual for me). I started taking the once a day pill, but after two days of chest tighness, I cut the dosage to half. The half dosage produces less chest tightness, but the runny nose continues. I am discontinuing the drug today.		F	50	1.5 months		8/22/2008
4	Allergies	None	It helps me to sleep better without as much drainage from my sinuses.	M	43	1 years		8/13/2008
1	Allergies	Severe depression, probably clinically psychotic at the end of five months of use. Actively suicidal -- hours and hours of paranoid and suicidal ideation, and nightmares. Four days after stopping the meds, I was pretty much back to normal.	Doctor did not tell me it was an antihistamine. I already knew that Benadryl OTC made me really depressed and would not have taken Allegra if I'd known. I found out by accident on the Internet -- otherwise I might not be here!
