| 4 | allergies | None really (insomnia?) | I don't think I've had any side effects really, but to be honest, i've had chronic insomnia and general trouble sleeping all of my life, so I don't think i'd notice if it were making my insomnia worse. And I've been on it so long, it would just seem normal to me... it does work well for my allergies. I did stop taking it recently for the first time in 10yrs (took 12hr for a long time, and then switched to 24hr when it came out - stopped recently cuz it was out of stock or something) and switched to zyrtec. Was REALLY tired all the time and slept more than I've ever slept. Not sure if it was the lack of Allegra or the Zyrtec causing that though. | F | 28 | 10 years | 1/9/2010 | 1 | Eustachian tube pressure | Nearly everything listed on the drug sheet by the 3rd day. After stopping the drug, I am now, one week later having heavy, mid-cycle menstrual bleeding. My last period ended only six days prior! | I am the one who logged the rating dated 12/30. I am coming back to add the menstrual bleeding. I felt much better within 24 hours of stopping the drug, and had just finished having a normal period, so this really caught me off guard! It is heavy and accompanied by more bloating than I usually experience. It's probably the worse period I have had in a long time (if that is what it really is as the was no time to build up a lining for a normal cycle!). I am waiting for a call from my doctor. | F | 43 | 3 days | 1/4/2010 | 3 | Adult Allegeries | Dizziness, very bad acid reflux, low energy, weight loss, loss of appetite, dry mouth, back pain in shoulders and lower back. Side effects got worse over time. | I took this drug for 3 weeks before I found this website. I had all of the bad side effects. 3 months later, my body is still recovering from the acid reflux. | F | 41 | 20 days | 12/31/2009 | 1 | Eustachian tube pressure | 1st day I simply felt strange, spacey. 2nd day I felt strange and a little bloated. 3rd day insomnia, nausea, headache, tension in shoulder/neck muscles, raw throat, listlessness, cold-sweat, fluttery heart, loss of appetite. | This is with the 24 hour pill. I wonder if it built up in my system over the 3 days. For me, clearly the side effects outweigh the hoped for benefit. I spent the majority of the 3rd day on the couch in misery. | F | 43 | 3 days | 12/30/2009 | 4 | Sinus and Allergies | I didnt feel any pronounced side effects except for being up in the nite sometimes due to the D | Worked great for me - I am trying to get pregnant and I am off it - and forced to take Zyrtec which I hate | F | 28 | 2 years | 12/17/2009 | 3 | The first few days that i started taking Allegra D i noticed that i wasn't very hungry and i stayed up later than normal but i felt great and my allergies were gone. | After about 5 days of taking Allegra D and feeling great with no runny nose or itchy mouth it all came back. I didn't change anything and continued to take allegra d every day but i have the worst itchy mouth and runny nose. the roof of my mouth itches so badly. why did my allergies come back i thought that the allegra would help? | F | 22 | 8 days | 12/7/2009 | 1 | congestion | dizziness, nausia, diarrhea, insanity, fast speach rate, no selective memory, shaking, insomnia, overwhelming feeling, OCD like symptoms, twitching, paranoia, rash, abdominal pain, increased heart rate. | since taking this drug, i have felt as if i were going insane. i was hearing angry voices in my head, commenting on everything i did. they also argued with each other and would wake me up at night. i felt as if my head were overloaded with facts, and i was retaining too many memories. everything i did was stored in my mind. i was also finishing tests unusually quickly and with amazing accuracy. i was beggining to believe that the pizza place i went to was putting drugs in my food, since i had never expirienced this before. it wasn't until my mother brought it to my attention that i had only been expiriencing these symptoms since taking allegra, did i look up the side effects. i shall never take this medication again. | F | 12 | 10 days | 11/24/2009 | 5 | season allergies, spec. ragweed | Jumpiness, but only rarely, and not as bad as with excessive caffeine | I have used many others (OC and prescrip), and this is the only allergy med that works for me. However, I cannot take the 24-hour version, only the 12-hour version. The 24-hour version keeps me awake. I take Benadryl at night. During the day it does exactly what it's supposed to do - it staves off the allergy symptoms and I rarely have any side effects. I am not drowsy or foggy as with others I've taken, like Zyrtec. The only other comment I would make is that I occasionally see no relief, and I have occasionally noticed that the "time-release" half of the pill has passed through without dissolving. That might be happening to me more than I know, and I wish I knew how to prevent that. :-O | F | 49 | 8 years | 9/28/2009 | 5 | Congestion, adult allergies | Not sure what can be attributed to Allegra-D exactly. Only take one pill in the morning after I eat breakfast. Seems to keep me congestion free all day. I am 5'3/4" tall and weigh Approx. 120. Try to eat healthy. Not a big appetite. I work out 3 times a week with a personal trainer for an hour each time. Maybe the exercise helps with me avoid some of the symptoms that others are suffering from. I have had occasional trouble sleeping but when I do I take 1 Benedryl to help me fall asleep. Last fall I developed bumps on the back of my head which eventually spread to my neck, lower back, pelvis area, inside of knees, and inside of feet. Saw both a dermatologist and an allergist. Listened to doctors and stopped and switched all kinds of stuff trying to get to the bottom of this even going off of allegra-D. I became miserable off of allegra-D and tried to use over the counter medications. Ended up at my Internal Medicine docter who put me back on Allegra-D with an addition | Allegra-D does get rid of the congestion through out the day and probably helps with energy for my work outs. I do not drink coffee and rarely drink caffine softdrinks. I have suffered from bad menistral cramps the last couple of years but chalked that up to the Essure procedure I had about 3 years ago. I have tried several times to stop taking Allegra-D but always end up going back to it. Before allegra-D I was misusing Affrine. I was miserabe before; totally stopped up, alot of sneezing, talked stuffy, watery eyes, always with tissues, could not sleep. My husband couldn't sleep because of me. Either he or I had to go to another room | F | 46 | 3 years | 9/1/2009 | 5 | severe sinus,allergies, headaches | This drug I cannot live without but on the other hand I cannot sleep over 2 hours a night My allergy specialist said it was due to the allegra-d | F | 60 | 2 years | 8/10/2009 | 5 | Allergies/Sinus/Chest Congestion | So far there are no side effects that I know of though I've been taking it only a couple weeks. | For about two weeks I thought I was sick either with a cold or sinus infection or Bronchittis and thought of allergies as being the culprit as well. Went to the Dr. He said it wasn't Bronchittis, think its my allergies, gave me samples of Allegra-DŽ 24 hour (fexofenadine HCI 180mg/pseudoephedrine HCI 240mg) Extended- Release Tablets, also some antibiotics for 5 days just in case something was going into my chest. After only a few hours after taking allegra-d, I could breathe better! And my nose stopped running/sneezing! It was amazing. Because for 2 weeks almost it was like non-stop! Sneezing/running/stuffy, awful! My allergies have never been so bad. This is August '09 & it started in beginning of July. It totally clears up my nasal congestion, running nose/sneezing, and also helps with tightness in my chest/breathing problems that feel like asthma(in which an inhaler helped temporarily). Normally I'd take Claritin-D for my normal allergies or when I'm around a cat that bothers my allergies | F | 26 | 2 weeks | 8/3/2009 | 3 | Allergies and sinus congestion | Loss of appetite, heart palpatations, spacey feeling, chest congestion, short of breath, heart burn | Of note, the symptoms are not completely new to me (except for the loss of appetite), but I definately notice that those symptoms are worsened by this drug. The bummer is that other allergy meds, like Reactine, make me drowsy and don't help with sinus congestion! | F | 42 | 4 days | 7/1/2009 | 4 | Allergies and sinus infections | Very high energy! When stopping meds, super tired. | I have been taking this for 3 years only when needed and it does help with sinus headaches and allergies, especially during school season. I take it at night before bed and have tons of energy for the day! Trying to take myself off allegra-D and I am so tired and just do not feel right at all. Weight gain for me---yuck! Tried other things but always go back to this because it does work. Side effects stink though! | F | 40 | 3 years | 6/29/2009 | 4 | Congestion | Tons of energy...anxiety....extreme loss of appetite | The doctor gave me 7 days worth of allegra to clear up congestion. The day of my first dose- i was almost immediately anxious and could not eat lunch- I ended up having a bagel for the entire day and just wasn't hungry. The same happened for the next two days. I'm not congested anymore so it helped with that! But i can't get over how much energy I have--and how much I don't want to eat--i usually eat every few hours. | F | 23 | 7 days | 6/26/2009 | 5 | pneumonia | Complete loss of appetite, slight dry mouth, dizziness, insomnia, and once in a while visionary hallucinations and colored spots and moving lines (wasn't bothersome at all to me) | I had a severely sore throat, and stopping that drip really helped as it hurt to even swallow at times. PS i drank a lot of coffee (6 shot coffees at that) and I did not get anxiety or have any issues with taking caffiene and allegra d. Overall it worked well for me. | M | 19 | 10 days | 6/10/2009 | 1 | cough due to post nasal drip | Took the 12 hour version. Couldn't sleep or concentrate for 30 hours. Very high anxiety. My cough worsened. Blood pressure went from 102/68 to 160/90 from one day to next. It took several days before things returned to where they had been prior to taking this drug. | Do not recommend. It contains a large dose of pseudophedrine. I also took Nasonex at the same time which may have contributed to symptoms, however, when taking Nasonex alone, I don't have any problems. | M | 63 | 1 days | 6/1/2009 | 5 | yes 12 hour | I've had NO side effects. This is the first drug I've taken without any problems. I've been on it for 10 yrs. I only take 1 tab of the 12 hour per day, on days needed, not everyday. Does give me a boost of energy, less than a cup of coffee. | All doses are not for everyone, know your body, know your medication, and work with your doctor for the dose best for you. | F | 34 | 10 days | 5/25/2009 | 1 | Eustachian tube dysfunction (ears) | While taking Allegra D, I immediately experienced gas/bloating, no appetite/nausea, acid reflux/heavy or full stomach discomfort, & lower abdomianl pain. Followed by increased heart rate, cold sweat, cold feet, nose, arms & hands, dizziness, feeling of fainting, minor headache, sensitive to daylight, body aches/soreness, weakness, tigling or numbness in arms & fingers, & erectile disfuncion. After a short walk, I noticed shortness of breath, back & shoulder pain, light headed & weakness in the legs. | Be aware before taking Allegra D 24hr. | M | 35 | 3 days | 5/22/2009 | 5 | Horrible allergies, sinus pressure | Decrease in appetite, weight loss, decrease libido, Increased energy. | Although i've experenced some side effects, this medication has worked very well on my allergies. Remember to drink alot of water! i wouldnt recommend taking it after 3pm. | M | 26 | 7 days | 5/17/2009 | 1 | Sinusitis | Breathlessness, nervousness, anxiety, sleeplessness, difficulty urinating | So glad I found this site. I was beginning to think I am losing my mind. The doctor thinks I'm hyperventilating. But I know better now. The same symptoms I experienced are listed over and over on this site. It's 4 am, I can't sleep, am hypernervous. Never taking Allegra again! | M | 54 | 13 days | 5/12/2009 | 4 | Seasonal Allergies | Insomnia, loss of appetite, jittery, possible irregular menstruation - excessive bleeding (?) | I'm not sure about the menstruation thing, as I have irregular periods anyway. | F | 29 | 2 weeks | 4/21/2009 | 2 | allergies | insomnia, a high-feeling, unexplained energy and yet no feeling at the same time. felt numb. | watch out for this powerful drug. i used to take the lower dose and just noticed the dr. prescribed the higher dose pill for me this year. i took a pill 3 days ago and am still feeling it's effects. can't wait for this feeling to pass. choose something else. | F | 31 | 1 days | 4/11/2009 | 1 | seasonal hay fever, sinusitis, | Last year took 24hr allegra d at bed time-slept well and worked wonders on my allergies. This allergy season-took 1st pill in a.m. It's 530 am and i haven't slept all night. I have severe sinus blockage, difficulty breathing, chest tightness, anxiety, nervousness, I'm 37 and in good health but was seriously considering that i was having a cardiac event. | I didn't notice anything last allergy season when taking it at night. Took it in A.M. just this one time and these side effects have seriously scared me. I will live with my allergies. | M | 37 | 1 days | 4/7/2009 | 4 | allergies | Insomnia, chest pain, anxiety | It's the first time in months that my head cleared up BUT I was considering going to the emergency room or to the doctor tomorrow. I have no history of heart problems and normal/low blood pressure. I am going to stop taking it tomorrow and see if I feel better as the days go by... | F | 40 | 3 weeks | 3/15/2009 | 5 | Seasonal allergies, Sprng thru Fall | I get occasional palpitations from it, so while I'm taking it I cut my coffee to two cups of 2/3 decaf per day, and that eliminates most of the palpitations. Beyond that, I do feel a chronic low-level caffeine-type high, which isn't necessarily bad, as long as it's not having a long-term affect on my heart... | I found that if I take it right before I go to bed, I sleep like a rock, and wake up maybe an hour earlier than I do in the winter (without Allegra D), but feeling completely refreshed. As for efficacy, it works wonders for my seasonal allergies! It's enabled me to quit asthma steroids, which have much more terrible side effects. :-( | F | 42 | 3 years | 3/14/2009 | 5 | Severe Allergies, Sinus headaches | slight Loss of Appetite, more alert | I love this precription. For me, the positives far outway the negatives. I can actually breathe and if I take this in the morning, there is no problem sleeping in the evening. And I have no more bloody noses from my sinuses being so irritated from the allergies. I have tried Zyrtec and claritan with no success. The only downside is insurance changes, so it costs more even with insurance. | F | 29 | 2 years | 3/10/2009 | 2 | allergies | sinus infection, earinfection in both ears | After taking allegra d for about a week my ears filled up with fluid, horrible pressure it felt like my ears were going to explode. when I went back to the Dr I found out I had a double ear infection and a sinus infection. who would have thought that a med for my allergies would have caused this. Think I will take my chances with the stuffy nose and sneezing! | F | 33 | 8 days | 3/6/2009 | 5 | sinus infection and allergies | Initially, decreased appetite and restlessness. After 1 week of samples provided by my doctor, I requested a full prescription. All side effects have subsided. | Chronic post-nasal drip due to 'generalized' allergy. Finally felt what it is like to breathe clearly! Initial side effects lasted about a week. Haven't experienced any other symptoms since then. I love allegra! Zyrtec and Claritin did nothing for me. Its not coverd by my insurance but its worth every penny. | F | 23 | 28 days | 3/4/2009 | 4 | Allergies, Chronis Sinus Infection | Some insomnia (would sleep until 2 a.m., wake up and not be able to go back to sleep). Also high blood pressure. | Works much better for me than OTC Claritin D. I take it whenever I feel a cold coming on. If I don't, every cold turns into a sinus infection. | F | 44 | 100 days | 2/9/2009 | 3 | Severe Cold | Insomnia! This stuff is painfully bad to sleep. I had no idea. I feel like I am on speed or something. | M | 27 | 3 days | 2/3/2009 | 1 | Nasal drip, bad cough | Took it at 5PM, had just returned from a relax daylong of meditation. My nose cleared up quickly. Then I feel asleep at 10PM. Woke up at 2AM, feeling like I just had 2 or 3 cups of coffee! Took some Ambien that I had laying around. Woke up 4 hours later, still feeling like I had 2 or 3 cups of coffee. I feel irritable, and its dissappointing because the day prior I had spent the day in total relaxation. I'd rather have my original symptoms. This drug is a bad trip! | M | 47 | 1 days | 1/25/2009 | 2 | I have terribly blocked ears | I took my first pill last night at dinner time, and after dinner cleaned my ENTIRE house in about 25 minutes. I wasn't sure why I had so much energy until this morning when I took another pill. I took my second pill this morning at 5am before work. When I got to work, my hands were shaking and I was extremely jittery. It is now 2:05 pm and Im still feeling the same... and I smoked about a half of a pack of cigarettes already, which I never do. My ears are still blocked, but of course I only took it for one day so far. I can't say I enjoy being so jittery all day, but I havent had a single thing to eat today, so it definitly suppressed my appetite. I don't think I will be taking this pill again anytime soon. | I wish my doctor would have told me about the side effects. I asked her if it would make me sleepy, and she told me that it shouldn't, but offered no other information on side effects. I think I'll call her about that... | F | 26 | 2 days | 1/23/2009 | 5 | Allergy symptoms | Insomnia, but only with the 24-hour Allegra-D. | Initially, I was prescribed the 24-hour Allegra-D. I felt great on it but it kept me wired at night and had trouble sleeping soundly throughout the night. I'm now on the 12-hour Allegra-D and have no problems sleeping at all. I take the 12-hour pill around 6:30am. | M | 46 | 7 days | 12/9/2008 | 5 | Seasonal Allergies | NONE! | This is the only allergy medication that works for me and the best part is I had NO side effects. Most allegy meds make me feel sleepy but this one felt like I didn't take anything at all yet I was allegy free. I love this stuff!! | F | 30 | 3 months | 12/8/2008 | 5 | Allergies & Hives | Mild insomnia. Just recently experienced severe dizziness & almost passed out...Dr. couldn't find anything wrong...NOW after reading comments here, realize it was because of drinking a fruit Margarita after taking the pill. | This is the only medicine that has worked for me...having allergies since childhood. Unfortunately, my insurance will no longer pay for it PERIOD! I am now at the mercy of over-the-counter meds. | F | 49 | 20 years | 12/2/2008 | 4 | I've been taking Allegra D for about two yrs now. I have adjusted my dosage to once a day early in the morning. I don't take it at night anymore...causes sleeplessness. Never take with an antacid. You'll get the worst cramps. I also don't eat around the time I take this pill. Nausea will occur. It's better to take a dose and eat in about an hour. Every allergy symptom I have had has gone away. Sneezing, itchy scalp, itchy back, morning congestion, runny nose.........all gone. It does pump me up abit. BUT, it's a great booster for a run or a workout! I no longer get sinus infections and I rarely get a serious cold. My resting heartrate is 60 and my BP is 120 over 60. The only thing that has changed is my menstural cycle....it's a little off | F | 40 | 2 years | 11/2/2008 | 3 | seasonal allergies | irritability, menstraul cramps and irregular bleeding,horrible dry mouth( i couldn't drink enough to get it to go away), fatigue,still had the feeling of excessive water in my ear | F | 23 | 23 days | 10/4/2008 | 4 | Allergies | Change in appetite. Lost 40 lbs. with this med and daily exercise. | This is for the Female that looks at her turds, it has a wax coating, it did not pass through you without dissolving. I take this in combination with Singular. Take in a.m. and again at lunch for restful night. | M | 47 | 6 months | 9/25/2008 | 3 | Ragweed allergies | I took an Allegra during the day and it really cleared me up however when I took before bed I could not sleep. I had to follow with a Benadryl just to sleep. I am a sound sleeper and this was irritating since I was tired and wanted to sleep. | I would just take in the morning. | F | 35 | 1 days | 9/17/2008 | 1 | Severe allergies, fluid in ears | Rapid Heart beat, dry mouth, couldn't sleep, anxious, irritable, no hunger when I ate within a hour my stomach had shooting pains and nausea. | After a week of taken this I'm taking myself off, definately not worth the side affects. At first made me think I was actually coming down with something, then doing some research found out it was this. | F | 24 | 9/8/2008 | 3 | For allergies | I couldn't tell if it was working or not, but I did notice the whole pill pass through and came out in my turds. So, I guess the pill never went into my system. Yeah, I would look in the toilet and there was a whole Allegra in my turd!! | I started breaking the pills in half to see if that helped, but occasionally I would still see parts of the Allegra D in my turds. | F | 30 | 6 months | 9/4/2008 | 1 | Allergies to replace zyrtec D | Insominia- heart palpitations- irregular heartbeat. No history of heart problems. | I was on this drug to replace Zyrtec D- used it less than 10 days. I would be very wary of this product. Stopped Allegra D yesterday- today no heart palpitations. | M | 44 | 10 days | 9/2/2008 | 5 | My only side effect is that I'm never hungry. | DRINK PLENY OF WATER. Dehydration is probably what most of your side affects are from. | F | 30 | 8/28/2008 | 4 | sinus/ear infection | Prescribed by my internal medicine doctor to be taken with 9 days of Levaquin - does ease congestion but I stopped taking the second one in the evening because I wasn't sleeping well. Not sure if rapid heart rate and physical sluggishness are due to Allegra or to the antibiotic. I have mild hypertension and my BP not affected at all but heart rate jumps by about 30-35 periodically during the day. Also am mildly diabetic and this has not changed my readings nor apparently has the antibiotic. | Today was my last Levaquin; i requested a few more samples of the Allegra D from doctor and got them -- wonder if I had a sinus infection at all since I am really just about the same as when I first saw the doctor and have finished my Rx. Guess a few more days will tell. The Allegra does make me feel better -- | F | 59 | 9 days | 8/7/2008 | 4 | Allergies | Dry mouth, trouble sleeping, increased focus, mild jitters, mild loss of appetite. | Seems to help more than anything else I have tried so far. Still have some stuffiness off & on, but overall I am less stuffy. | F | 36 | 3 days | 8/2/2008 | 4 | Allergies, Hay-Fever, Deviated Sept | Never really experienced any side effects. Recently started taking Lisinopril 10mg and experienced some effects but thought it was the Lis. Now up to 20mg of Lis and have dizziness frequently and almost fainted a few times. Maybe a combination of the Allegra-D and the 20mg of Lis is the problem. | It really helps my allergies and deviated septum issues, but don't know if it plays well with others. I am taking the Lis because the metro.. was interfering with my allergy shots. Has anyone else felt dizzy while taking Allegra-D with Lis? | M | 40 | 3 years | 7/22/2008 | 1 | seasonal allergies | insomnia, loss of appetite, racing heart, extreme irritability | I have been on this medication for 4 days and am taking myself off of it. Since taking the medication, I have not slept more than 2-3 hours a night, if that. My heart began racing today. I am generally an easy going person, but over the past 4 days have become very cranky and irritable to the point that I am angry and frustrated with everybody and everything (this could also be related to the sleep deprivation). I work full time and am the mother of 3 children, and do not feel I can function at home or at work. This is the worst medication I have ever taken. | F | 36 | 4 days | 7/19/2008 | 4 | Allergy to pollen | I feel happy and have a lot of energy. My allergy symptoms are gone. I am taking the 12 hour Allegra. I have so much energy I am running out of chores to do. I had to take valium to calm down enough to sleep at night. I think I am only going to take it in the AM and see how that goes. | So far, so good. | F | 37 | 1 days | 7/18/2008 | 3 | Allergies and congestion | rapid heart beat, insomnia, irritable and angry | I am sitting here with a heart monitor reading everyone's comments. My doctor recommended me to stop taking Allegra-D immediately. I don't have a history of heart problems and my blood pressure has always been normal. I never put two and two together until I looked up the side effects after talking with my doctor. I have been taking this drug for a year and a half. Please make sure you have your doctor check your heart rate every time you go into the doctor. If my family doctor would have checked it just once in the last year, I wouldn't be sitting here with a heart monitor. | F | 36 | 1.5 years | 7/17/2008 | 5 | allergies | a week of insomnia/interrupted sleep. SEVERE reaction with wine. I was taking the med at night for a few days and realized that while I could function on 3 hours of sleep, it probably wasn't healthy. I started taking it in the morning and waiting a few hours to eat. Side effects disappeared after another week and have had no problems since. | I would like to continue on the wine subject. The warnings specifically say to avoid fruit juice. I assume now that wine would be classified as fruit juice. After drinking a glass or two, I became violently ill and the feeling lasted for a full 24 hours. If you are a wine drinker, beware. | F | 37 | 26 days | 7/14/2008 | 3 | oral thrush, allergies | vertigo, dizziness, fainting, collapsing, inability to walk straight | Slightly reduced nasal dripping and throat irritation but produced severe side effects | M | 28 | 4 weeks | 7/11/2008 | 1 | severe sinus infection | dry eyes and mouth, constipation, blurred vision, hungry but when I go to eat, can not stomach a lot. Insomnia, bad nausea by the third day | My doctor only prescribed it for me for 10 days 1 pill instead of two daily and I have to finish 4 more days for a total of 10. Can NOT wait to get off of it!!! I will hopefully never be told to take this again | F | 49 | 6 days | 7/6/2008 | 3 | seasonal allergies | insomnia, jittery, nervousness, increase heart rate, irritability, dry mouth, loss of appetite, nausea | This drug definitely clears up the allergy symptoms, but I'm not sure if it's worth the trade off! | F | 25 | 2 days | 7/1/2008 | 4 | seasonal allergies | nervousness,heart palps, stomach upset, body ache. Similar to every bad side effect previously mentioned. I am pissed at my Doc for not even thinking this could be the reason for my high blood pressure.I am taking myself off this stuff before I have a heart attack. | I have been taking this drug for a long time and now have high blood pressure. I am not overweight. I have had all of the side effects everyone else has had. So I stopped taking Allegra D last week and since have had very bad headaches. I reluctantly took an Allegra D last night and the headache went away. I have tried other things but this is the only poison that works. | F | 49 | 5 years | 6/24/2008 | 3 | seasonal allergies | sleeplessness, anxiety | I take the 24-hour tab at approx 8am, only when seasonal allergies are flaring up. It works very well to control allergy symptoms - but here it is, 3am, and I'm wide awake! (This from a person who can usually sleep through anything.) I seem to fall asleep OK, but get very restless sleep, tossing and turning, and end up putzing around the house in the middle of the night until it finally wears off. | F | 39 | 120 days | 6/20/2008 | 1 | nasal congestion | took the24 d around noon could not sleep at all did not eat much | done after 3 days hope the dr has a better idea | M | 40 | 3 days | 6/19/2008 | 3 | hayfever, seasonal allergies | Intermittent sleep, Complete loss of appetite, I have lost 20 lbs in about 2 months... not good for me. Back and neck pain, severe dry mouth, severe headache that begins just above and behind the left eye. | Works for the allergies but can't deal with side effects, I stopped this morning after reading this site. | M | 32 | 2 months | 6/18/2008 | 5 | allergies | Lost 10 pounds less than a month. IT'S A GREAT PRODUCT! clears you up! | I take it once in the morning. I do have trouble sleeping, but i had trouble sleeping before. Sometimes i use a saline solution nasal spray, to help with the dryness and to clear my nose. The combination works wonders. | M | 38 | 4 weeks | 6/15/2008 | 4 | sinus congestion and pressure | It definitely worked but after taking it for 3 years on and off I finally decided to check your webpage out and realized that when I am on the medication I experience jitters, heart palps,restlessness and anger when there isn't any need to be angry, and now I had a severe cold sweat and nausea episode after taking Allegra D with coffee and within hours I felt as though I would faint. I never thought all my ups and downs could be caused by this medication but now think this has been my problem. I loved this medication and it really did work but I am now going to go off it. | I just wish I had checked about serious side effects more closely. | F | 60 | 3 years | 6/14/2008 | 5 | Allergies | On 2 Occasions, i found that the pill passed through whole. However, did not upset my stomach or give me any other side effect associated with it. I spoke with my Dr. and he said it is very, very rare, but not harmful. If it continues to happen obviously switch meds because i am not getting the correct dose needed. | I only take allegra D in the AM, and i take zyrtec in the evening. The combination works well for me, and the side effects are so mild that i will continue to take it. | F | 26 | 4 months | 5/28/2008 | 1 | Sinus Cold | My Side effect: Insomnia! | Dr. Prescribed one pill twice a day! The first night (after taking one pill), I slept 2 hours. The second night, I slept three hours. The third day I only took one Allegra-D pill in the morning, but still only slept about 5-1/2 hours. I typically slept 8 hours/night. This stuff totally messed up my sleep! I would rather deal with the cold sickness, verses the lack of sleeping. One odd thing: Though I have had very little sleep, I do not feel tired! No yawning, nodding, nothing. I am perky all day, but then just lay in bed waiting to fall asleep. This whole situation concerns me! So I am off the "sauce". | F | 35 | 3 days | 5/9/2008 | 4 | Constant drip | I find myself just short of being a little wired..but not uncomfortable..hoping it goes away | I've taken everything in the book and this is the first med to completely stop my body's constant build up of phlegm. I din't have a dry mouth. I have no unsettling side effects. I can sleep just fine. I'm not drowsy. As a new user, I hope that side effects that others mention, do not kick in...so, for the moment, I'm extremely pleased with the med. | M | 58 | 5 days | 5/5/2008 | 3 | Allergies | insomnia, chest pain, irritability | I have been taking this for a week and a half and the chest pain is unbearable. Also, I haven't slept thru the night since I started it. I probably wake up at least 5 times a night. | F | 26 | 1.5 weeks | 5/2/2008 | 2 | allergies ictch eyes | indigestion. I took my first pill 4 days ago in the morning and later that evening had major indigestion... and now the indigestion hits me within the hour | Four days ago I thought that I either ate too much or I had acid reflux, but today I took the pill later in the day and guess what? Indigestion hit me within the hour..no more allegra d for me! and it is supposed to be non-drowsy, but its not 100% more like 75% non drowsy and lots lots of Indigestion | M | 100 | 4 days | 4/25/2008 | 5 | Allergies, congestion | No side effects after six days. It has helped a GREAT deal. I have read all of the comments on this page and almost became a hypochondriac. Hopefull I will be ok with it as it does work for me. | The snoring has dramatically quietened down, if not totally stopped. Feel 100% better | F | 43 | 6 days | 4/23/2008 | 4 | Nasal congestion, sneezing | Dry mouth, light headedness, intense orgasms (maybe the last one isn't so bad) | M | 31 | 7 days | 4/19/2008 | 1 | Every word of the fourth guy down on the ratings page is word for word every problem I've experienced. -Rather have the allergy. | F | 33 | 4/11/2008 | 1 | Seasonal Allergies | ED...imagine the shock!!! | I have been taking Allegra for a couple of years now...every day. Occasionally, when my nose is really stopped up, I'l take an Allegra-D. With regular Allegra, I'm fine. With Allegra-D, I experience ED for 24-36 hours after taking. I have never had this problem before, and don't have a problem if I don't take the 'D' version. I'll NEVER take another Allegra-D! | M | 51 | 2 years | 4/3/2008 | 4 | Sinus congestion, Sneezing | None really. Maybe a little tired at first but nothing that would keep me from normal activity. | Wow, a lot of hypochondriacs on here, this allergy drug pretty much had no side effects mentioned by everyone here. I took it at 10 am and fell asleep great by normal bedtime(11'ish). It helped dry my sinus and post-nasal drip but I can get the same effect by taking Sudafed. | M | 20 | 1 days | 4/2/2008 | 1 | Sinus/Allergies | No side effects first 12 days of taking this; then they kicked-in: body ache, headache, racing heart, then a few hours of dialated eyes/double vision & borderline panic attack---rather, um, hard to continue taking while remaining gainfully employed! Had to stop after 8 days, cant conduct business meetings while, essentially, stoned. | My doc prescribed this med along with Singular 10MG at the same time----so am not clear which med caused the largest side effects. Too scared to try one at a time to see, after my "day trip" at work. | F | 42 | 12 days | 3/25/2008 | 4 | Nervousness, a faster beating heart | This medicine really helped clear up my allergie problems, but it made me get really nervous and my heart would beat faster around a lot of loud commotion. I am just trying it for 3 weeks, but i hope the doctor will give me something else. | F | 17 | 6 days | 3/13/2008 | 1 | Allergy | I have taken this medecine for allergies for over one year.And the side effects suck..I stop taking this crap todoy becuse all of these side effects insomnia, nervous, headache, heart palpitations, shortness of breath, dry mouth , made blood pressure high, I will deal with my allegies another way....Stop allegra d it sucks | M | 30 | 1 days | 3/11/2008 | 3 | sinus problems | Irritability, feel tired but cant sleep, fast heart rate, cotton mouth, loss of appetite | Am experiencing drowsiness but can't sleep. I was told to take Allegra-D every 12 hours, but I will not take it at night since I would definetely not be able to sleep. Feel very irritable. Feel hungry but nothing looks appetizing enough to eat. Dry mouth. Fast heartbeat. Besides all of these side effects, I do feel it has helped my sinuses. My nose is not congested now. | F | 32 | 2 days | 3/7/2008 | 5 | hay fever, itchy scalp | Loss of appetite (went away after a month or so), extra energy, I only take one pill in the morning because the afternoon pill will keep me awake at night. | I've tried claritin with no results whatsover, but the allegra-D which was originally prescribed for my spring allergies has become a staple for me as I have an itchy scalp (several years now) which no doctor has been able to cure. The allegra is wonderful to keep the itch in check and not make me sleepy! | F | 45 | 10 years | 3/5/2008 | 2 | Allergies | Firstly, my ears do not clear up. I feel like I am under water most of the time. I don't always take at it at night and just recently started because my allergies have been really bad. It just dawned on me today that the cause of my insomnia might be due to taking the medication before going to bed. Who knew ! | M | 44 | 2 years | 3/3/2008 | 3 | Allergies | Extreme nausea, some dizziness, slight blurred vision, jitters, and a feeling of mental fog. | I experienced less allergies while taking this med. I just started allergy shots and my doctor gave me Allegra-D samples to help with nasal congestion. My nose has cleared up however, the past Monday I threw up 3 times from 1AM-3AM and by Wednesday, I even took a pregnancy test. The nausea was very severe today. My appetite has dwindled to the point where I can't think of anything I want to eat even though I feel hunger. Today I noticed a feeling of not being aware of my surroundings and being in a dream-like state and also a nervous feeling. The only thing I am doing different is taking Allegra so I will discontinue as of now since the nausea I felt today was so terrible. It was constant from 3PM- right now (2:58AM). Can't sleep. Claratin D is better. Never had problems with that. Last resort is Benadryl wich helps me sleep also. | F | 35 | 2 weeks | 2/24/2008 | 1 | fluid in ears due to allergies | extreme dizziness (to the point of vertigo), fast heart rate, headaches, chest pain, a tingling sensation on top of my head, feeling jittery, nausea, cramps, insomnia, no appetite, and sensitivity to cold (my hands and nose got extremely cold). | This medicine is absolutely awful. The side effects were just about unbearable, and my doctor ordered me to stop taking it after only two days. If you are AT ALL sensitive to drugs or prescription medications, DO NOT take this medicine, especially if it's the 24-hour version like I was on. The fluid in my ears seems to have gotten worse, as well -- the ear pain is still there. It feels awful. | F | 17 | 2 days | 2/21/2008 | 1 | Allergies | Eye floaters. Anxiety, confusion. One dilated eye. Racing heart, emotionally upset. Every time I tried to go to the restroom not much happened. Headache, dry eyes and mouth. Neck pain, pain everywhere actually. Blurred vision. Horrible nightmares. Interupted sleep and insomnia. I feel disconnected, very, very strange feeling. | Suffering from the allergy is nothing compared to this. I will never take this medication again as long as I live. This medicine made me feel like I was going to die. I see another listed eye floaters and blurred vision. These bad reactions I have been having to Allegra D brought me to this site. I am sorry that so many others feel these terrible side effects, but am relieved to know that my suspicions about Allegra D are on target. I'll just get a bigger box of klennex and deal with the allergy with no medication. Many of them make my heart race. This medicine is more like poison. | F | 43 | 2 weeks | 2/17/2008 | 5 | allergies/allergic rhinitis/headach | dryness in eyes and mouth, weight loss since i've started taken it. almost 20 pounds in 4 months... | I love it..controlled my post nasal drip,(don't feel like I have to contantly clear my throat)hardly any headaches anymore, and my snoring has gone.. | F | 35 | 4 months | 2/2/2008 | 4 | Allergies | Insomnia - took awhile to figure out the source. I made the mistake of taking the Allegra-D at night before going to bed...didn't realize it would do this. | The only drug I can take during the day and still function. All others that I've tried leave me feeling completely stupid. | F | 39 | 8 years | 1/29/2008 | 2 | allergies, sinus congestion | When taking a dose in the AM it worked well enough. Not enough side effects to bother with. Did it help my symptoms. Maybe. About as well as anything else. When I took it at night , I definitely had insomnia. (Did not know that as a side effect til later.) But I felt the allegra D was not taking care of my symptoms as well as I would like. So at night I started taking a Drixoral green- 12 hour) and then the allegra D in the AM. The next day I was taking a flight. During my layover I had a glass or two of wine. I started walking to get my next boarding pass.I do not remember much after that. Friends tell me I called them and made up wild stories of being detained by 20 policemen and being accused of being a terrorist, etc. and well the story goes on. The truth is 3 paramedics came up to see if I was okay and 1 airport security officer. AFter several hours I was better. I have taken sinus meds all my life and also had a little wine but never experienced this. The side effects describ | M | 50 | 24 days | 1/28/2008 | 4 | Allergies | Lose of appetite, weight lose without changing my habits. I only take it first thing in the morning and it really gets pepped up for sure. I crash in the afternoons though which sucks because I am in school at night and now I have to take a nap before I can get anything done. Luckily I get off at 4! | I have been exeriencing Diarrhea and wondered if that was a problem for anyone else. | F | 38 | 14 days | 1/21/2008 | 4 | severe congestion | the benefits out way the side effects, only side effect so far is brief sleep interuption due to taking the 12 hour pills but not significant enough that i cant fall back asleep. I may try taking it once a day to see what happens, but really satisfied with the results right now. | works really well, the night congestion, the morning blood shot eyes, the late night congested headache, the wake-up congested headache, snoaring all gone...it feels good to breathe through the nose,especially when sleeping. | M | 46 | 30 days | 1/16/2008 | 1 | Head Cold | Chest wall pain, irregular heartbeat, increased heart rate, extreme colonic cramping, constipation and insomnia. | The first day I felt okay. By the second day my normal heart rate of 60-70 went up by 30 points, my chest hurt and I was missing every 4th or 5th beat. I also suffered painful colon cramps and constipation. The drug combo kept me awake all night long. I've only taken 3 of these pills and am going to deep-six the bottle. I'm going back to clorpheniramine for my antihistamine choice when I need one. | M | 64 | 2 days | 1/14/2008 | 3 | allergies, hay fever, pollen, molds | The decongestant caused exciteability and mild insomnia. I called them my Tigger pills because they gave me lots of energy, but are bad to take at night! You will not need coffee with this drug. Warning: combining Allegra-D with alcohol is a BAD idea. One drink seemed to be okay, but any more than that caused severe dizziness, though I don't know if it's the Allegra or the decongestant that is causing that reaction. | If you're experiencing these symptoms, ask your doctor to put you on a regular antihistimine without decongestant (e.g., just Allegra, no -D!). You can always take a separate Sudafed (or similar) decongestant as needed. Be extremely careful with alcohol! | M | 30 | 2 years | 1/8/2008 | 3 | Seasonal allergies.Sinus Congestion | After taking Allegra-D for about 3 months I experienced an inability to urinate if I woke in the night. My Doctor took me off of it immediately citing "urinary retention" as a side effect in some people. After reading this site, I am guessing that my recent depression, loss of appetite and sex drive are probably a result of Allegra-D. | It is a great medication for clearing sinuses. First time in several years where I've been able to breathe fully and clearly. But not worth the agony of not being able to pee! | M | 51 | 3 months | 1/5/2008 | 5 | allergies | The only side effects I noticed was cold nose, hands and feet. Also a decrease in appetite which is not a bad thing for me since I tend to overeat anyway. | I take one in the morning so it WON'T keep me up at night, I have no heart palpatations and am not jittery at all. I feel great on this stuff with no runny nose or sneezing anymore. | F | 44 | 2 months | 1/3/2008 | 1 | Chronically blocked sinuses | Jittery, but lacking in energy. If sleep was possible it was only for 2 or 3 hours. Excessive urination. Depression,anxiety,thoughts of gloom & doom, no drive, no "pep". | Every 2nd night I would take sleeping pills to catch up on sleep. Of course this was grossly unhealthy but one has to function. Allegra & Allegra-D were actually quite effective in drying up the sinuses, but the cost to my health was far too high. I'll do whatever is necessary to get by without this awful intrusion into one's system. Good riddance! | M | 70 | 15 days | 12/22/2007 | 5 | allergies | none | clears the congestion quite well | M | 35 | 2 weeks | 12/7/2007 | 1 | Allergy and congestion | Bad heart Palpatations; terrible anxiety; blurred vision; eye floaters; sore back, neck, and backs of legs; insomnia where I would be up for 36 hours at a time; loss of 30 pounds in 3 months without excersize; terrible gas and change in bowel movements; severy dizziness; labored breathing where every breath feels like I only fill half my lungs than have to breath in harder to continue filling my lungs to capacity; central apnea where i would feel like I stop breathing as soon as I fall asleep; numbness in calf muscles and feet, as well as a numb dizzy feeling in the back of my brain; ears would get red and feel like they were on fire, so would my cheeks down to my neck; sharp pains from time to time in heart and chest; confusion; loss of sex drive (but not completely); blood pressure went up from a normal 113/76 to 132/85; and a bad case of hypochondria because I couldn't pinpoint where all these symptoms were coming from. Every doctor I saw (5 total) said it was NOT the Allegra-D, jus | STAY AWAY FROM IT! The two ingredients of Allegra-D are fexofenadine and Psuedoephedrine. I recently learned that the psuedoephedrine is the main ingredient used to make crystal methamphetimine (or it usually is), and I found out because a doctor thought I was a user of the drug when i took a urinanlysis for a regular physical. He told me that they found crystal meth, which shocked me because I don't even drink alcohol or smoke cigarettes. To make a long story short I found the fact about the pseudoephedrine. None of the 5 doctors I saw realized this...either they are in business with the drug manufacturer, or they are just all ignorant of the fact. I just found all this information out and stopped taking the medication this past Friday. You'll never again see mee...on Allegra-D | M | 29 | 3 months | 11/12/2007 | 1 | Head cold | insomnia, nervous, headache, heart palpitations, shortness of breath, dry mouth , made blood pressure high, o energy. | After taking this medicine I immediately started having side effects. I thought after I took it for a few days, maybe it would get better . The longer I took it the more symptoms I had. After taking it for 6 days...I thought I was going to die. It was horrible. I had not slept over 2 hours a night all this time. After being off it for 3 days ...I still have no energy,shortness of breath, I cant even go up just a few staires without getting out of breath ,,,and having to sit for a while to get my breath again. Worst medicine I have ever been on...and also very costly.100.00 down the drain and probably has damaged my health. I told my doctor I had trouble sleeping before she prescribed the med ...she said..Allegra d should not effect me in that way. I will never take this horrible medication again. | F | 63 | 6 days | 11/6/2007 | 1 | Stuffy nose/Allergies | Experienced extreme nervousness--jittery. Feel an extreme type of pressure in the head...like a tight helmet. Right hand fingers tremored. Raised blood pressure. Heart palpitations. Upset stomach and loss of appetite. Very odd feeling. | Definitely will discontinue Allegra-D. Cannot tolerate the side effects. | F | 50 | 27 days | 10/30/2007 | 5 | Allergies | None. All you morons who take it before to bed...of course it's going to keep you awake!! Any Decongestant on the market will have the same effect. Zyrtec-D, Claritin-D, Sudafed. The active ingredient is an ephedrine, exactly like caffeine. Don't take it before you go to bed dummies. Think before popping a pill in your mouth. | M | 38 | 8 years | 10/28/2007 | 2 | allergies | Severe anxiety, loss of appetite, depression | Allegra-D worked for my allergies completely. However, I would suffer through my allergies than deal with the severe anxiety/depression that I did because it's just not worth it. I lost 10 pounds in 3 months with virtually no explanation. I thought I was going crazy until I found this site and everything started to make sense about my anxiety. | F | 20 | 3 months | 10/27/2007 | 5 | stuffy nose / sinus | severe foggy head, suicidal thoughts, dry mouth, ringing in ears, constipation, backache, lack of appitite (lost 4 lbs). | This medicine does a great job of clearing out your sinuses!! But be very careful of the SERIOUS side effects. They don't all start at once. One symptom comes on every couple of days, so it took 14 days before I finally figured out what it was. Side effects so debilitating, by the 2nd week, I could hardly function. I would drive to work and try to find something that I could run into that would be sure to kill me, not just damage my car!! Stopped taking them, and in 2 days I am back to normal. Use with caution. | F | 40 | 14 days | 10/23/2007 | 1 | Allergies to dust, pollon, dander | Every possible terrible symptom you could imagine happened to me. I've taken it for a year or so. I have depression and it made it 10 times worse. The anxiety was absolutely terrible and I completely lost my sex drive. I haven't slept well in months and months it seems and my back and legs are ALWAYS in pain. Not to mention the insane levels of irritability. I just discovered this site and I will never take Allegra-D again. | This is the worst medication I have ever been on in my life and I have been on allergy meds for as long as I can remember. | F | 20 | 1 years | 10/10/2007 | 1 | Sinus Drainage | Awake almost all night for two nights in a row. The medicine didn't help that much with my symptoms. I still coughed a lot and had some drainage. | My doctor gave me samples but didn't tell me about side effects. If I had known, I wouldn't have taken it. I wouldn't recommend this medicine. | F | 40 | 2 days | 10/6/2007 | 4 | seasonal sinusitis/allergies | trouble sleeping, lots of energy, loss of appetite | First tried it twice a day and couldn't sleep ... but didn't want to give it up since it cleared up all sinus problems. now I take it just once in the morning and I sleep fine at night. Seems to work 24 hours even though it says 12. For those having trouble sleeping, I recommend trying just one. Worked for me! | F | 50 | 10 days | 9/29/2007 | 5 | congestion + allergies | jitters, upset stomach | I only WISH I lost my appetite taking Allegra - D as others have mentioned. I also had no problems sleeping... of course I can sleep through a freight train. My nerves were somewhat on end and I could not drink coffee otherwise I had the shakes. | F | 38 | 2 years | 9/27/2007 | 5 | Allergies | inital sleeplessness, high energy levels, loss of appetite, weight loss | Initially I had a hard time sleeping through the night. After about 5 days I had adjusted to it. One fun side effect is loss of appetite. I have lost 20 pounds. I heat normally, but have lost the feeling of wanting to snack and over eat all of the time. My allergies are almost non existant now. I can finally take a deep breath through my nose. | F | 34 | 4 months | 9/26/2007 |
