| 2 | Nasal congestion, clogged sinuses | ITCH when I am even an hour late taking a dose, nightmares, depression | the ITCH is why I have to quit Allegra. It did a good job relieving my nasal congestion but the itching when I am late taking it is unacceptable. I think I better quit now to make the withdrawal easier and will probably use Benedryl to calm the itch for the first week or so. Had taken Claritsn before but found myself still frequently congested. Not sure what to do next, perhaps it's time for the shots. | F | 38 | 45 days 180 mg 1X day | 10/19/2011 | 1 | allergies | nausea, migraines, heartburn, dizziness, fatigue | I have been taking various prescription allergy medications for about 5 years now daily with no problem. I ran out of my prescription allergy medication and decided to try allegra until I could get a refill. I have tried claritin OTC before with no problems. By day 2, I literally could not get off the couch I felt soo ill. I decided to check online and discovered these are side effects of allegra. I will never take this medication again. | F | 27 | 3 days 180mg 1X day | 10/18/2011 | 4 | Allergies | Initially hyperactivity, mind raising, sleeplessness | I found that my side effects were short lived. I had issues for maybe the first 2 weeks where I couldn't sleep and I was really hyper. It's leveled out and I feel normal. This is exactly the opposite of my side effects from Zytec, being constantly foggy and tired no matter how much sleep, side effects that never left even after years of use. I would say it works slightly less than Zytec for nasal allergies, but I would rather not be foggy all the time. Oddly, allegra cleared up some skin allergies for me. Zytec does not. | F | 28 | 6 months 60 1X day | 10/11/2011 | 1 | Bad allergies | Insomnia, Anxiety, heart burn, stressed, depressed for no reason, mood swings, back talk to parents. | I started taking this horrible allergy medicine, for my severe allergies. I use to take Zyrtec, but that didn't turn out too good. Then I started to take Claritin, and Claritin works great. But, we ran out of Claritin, so I started to take Allegra. And boy, it was BAD!!! I had extremely bad insomnia. So bad, that I had focusing problems in school!!! I had heart burn, and panic attacks. It was horrible!!!! I do not recommend this yucky medicine, unless you wanna turn into a depressed psychopath! | F | 13 | 2 weeks 1X day | 10/11/2011 | 2 | Allergies | Heart palpitations, gas in chest, anxiety, insomnia. | I used to take generic allegra (fexofenadine) for 10 years without event until my insurance company stop paying for the drug because it is now OTC. I bought the named brand allegra and had an awful response. After 2 days of the pill, I was awoken at night with heart fluttering. I could not return to sleep. Gas in the chest soon accompanied the fluttering. Anxiety and insomnia shortly ensued from the fear of kicking the bucket due to the heart fluttering. When I called up the company they said that while the active ingredient (fexafenodine) is the same, the inactive ingredients are not uniform across the board. So perhaps something in the inactive composition caused this awful effect. | M | 38 | 10 years 180 1X day | 10/6/2011 | 2 | reduce congestion, especially lung | Itching! Whole body felt like it was crawling with little bugs, worst on days I skipped Allegra, but I had NO itching before. Sleeplessness, occasional dizziness, increased anxiety, some loss of motivation / depression, heartburn for only the 2nd or 3rd time in my life. | All of my symptoms as well as most of those reported here (including night terror / restless legs) are common symptoms of yeast overgrowth (candida albicans). I am prone to this and have had it in balance for years with diet and probiotics. It seems as though Allegra has destroyed that balance and allowed the yeast to again multiply out of control, which would explain why for me and many others the itching is worst when stopping. It is caused by yeast, but suppressed by Allegra while on it. Once you're off, the yeast are still there, but no suppression. As yeast infections are not common (especially in men), most people can probably take Allegra without side effects, but for those of us prone to yeast, whoa! It DID help reduce my allergy symptoms considerably as my lungs and sinuses mostly dried out, but not worth the itching and mood changes. | M | 41 | 8 days 180mg 1X day | 10/1/2011 | 1 | allergies | FOR MY CHILD :SLEEPING DISORDER, HALLUCINATION | I WOULD NEVER RECOMMEND THIS PRODUCT TO ANYBODY | M | 7 | 1 days 30 MG 1X day | 9/22/2011 | 1 | Seasonal Allergies | Severe depression in a teenager with no previous history...so bad we were going to contact a psychiatrist. I woke from a sound sleep with the eureka moment of making this connection and RAN to the computer. Thank God for this site! Claratin had only good effects, but seemed to lose effectiveness after many years. We tried generic allegra and it worked great for the allergies, but I'd rather hear my son sneeze 1000 times than hear him wish he was dead ONE TIIME!! | It is in the trash where it belongs. PLEASE tell all of the doctors and pharmmacists about these dangerous side effects. | M | 17 | 3 weeks 180 MG 1X day | 9/18/2011 | 3 | sneezing, sore throat,running nose | tightness of chest, trouble breathing, and vivid nightmares and night terrors; I would wake up screaming in the middle of the night from a nightmare, near the end of taking it i also started to sleep walk. I also noticed I started to become very stressed and nervous for no reason at all. | I have very bad allergies near august/sep. and in the spring and have never found a medicine that works as great as Allegra has, i was very disappointed that it caused me such intense side effects since it really helped clear up my running nose, and helped my sore throat. | F | 22 | 8 days 180mg 1X day | 9/14/2011 | 1 | allergies | Got restless legs really bad and couldn't sleep on the first night. | would not take again. | F | 24 | 1 days 30 2X day | 9/12/2011 | 4 | severy allergies | I experienced severe constipation - on 3rd day I experienced disgusting pain shooting up back passage. Went off tablets and everything returned to normal within 3 days. | worked fine to cure allergies, but I will try taking much smaller dosage, like half a 30mg tablet. I have read elsewhere on the internet that even 5mg can help allergy sufferers. The larger doses seem to be needed for hives or ant bites, etc. | F | 59 | 3 days 180mg 1X day | 9/3/2011 | 3 | allergies | headache, lethargic. there are periods of calm, no itching, no sneezing, but at least 1x per week i get a horrendous 3-4 hour allergy attack, itchy body, itchy ears, itchy throat, itchy nose, itchy/puffy eyes, back to back sneezing, sometimes 4-5 sneezes at a time, running/flowing liquid out of nose, just awful--only feels better when i plug my nostrils with paper. | not sure whether i will continue with it after this bottle. oh headache coming on, bye. | F | 34 | 1 months 180 MG 1X day | 8/29/2011 | 3 | Skin rash, hives | Second day of taking it and am having waves of dizziness so that I am cautious about driving home from work today! Looked up this site to find it is a common side effect. | F | 64 | 2 days 180mg 1X day | 8/24/2011 | 2 | allergies | lethargy, depression, racing heart | I only began to suspect the Allegra after I missed a couple of doses and then started back on it again. All spring and summer I've had the blues and several times my heart went pounding out of my chest. I'm normally a very high energy person and I was just so tired. When I was off of it for a couple of days my mood was better but my allergies were bad so I started back on it. That is when I made the connection and thought I would look for more information and see if anyone else had this experience. So glad to find some answers. I will definitely quit taking it. | F | 47 | 80 days 180MG 1X day | 8/21/2011 | 5 | Allergies | None - it worked great. | Actually I used Allegra D for at least 8 years. During hay fever season I would take 2 tablets per day as recommended and never had any side effects of any type. | M | 52 | 8 years 60 mg 1X day | 8/20/2011 | 1 | seasonal allergies | DEPRESSION, lethargy, inability to concentrate, crying | This drug is horrible. I started taking it for ear problems associated with allergies. It works for allergies but sends you into a horrible state of depression. I had suspected this as I had similar mood change in Spring but was not taking it as regular. AS SOON AS I STOPPED taking this drug I was back to my regular mood. THIS WAS SCARY AND I DO NOT RECOMMEND THIS DRUG!!!! It was also scary to find out that the local pharmacist had no idea of this side effect... | F | 41 | 7 days 30 mg 2X day | 8/18/2011 | 1 | Allergies | I have been taking Zyrtec and ran out so decided to try Allegra. This stuff is horrible! I had anxiety attacks the first day. I hallucinated and had horrible night mares. I even went for a walk around the neighborhood and got lost. I have lived where i am for 3 years. This stuff is satanic.. | M | 24 | 2 days 180 mg 1X day | 8/15/2011 | 5 | Seasonal allergies, stuffy nose | None | I use to have horrible allergies every summer, but Allegra worked great and relieved my allergy symptoms almost totally! | M | 17 | 3 weeks 2X day | 8/10/2011 | 3 | Seasonal Allergies | Dizziness, feeling out of it, jittery, light-headed, drowsy | Seems I can tollerate it if take it only a few times a week. But if I take it regularly and allow it to build up in my system the side affects start occurring. I used to take 180 mg but lately haven't been able to tolerate.. makes me very drowsy. So, I went to the 60 mg... but as it builds up the side effects start occurring. | M | 49 | 2 years 60 2X day | 8/3/2011 | 1 | Sneezing, itchy eyes | Persistent nausea, headache, fatigue, irregular menstrual period | As of today, i have just realized that all these symptoms are side effects of this drug. This is the only drug i have taken for the past 18 days. Definitely will be my last dose.. | F | 25 | 18 days 180mg 1X day | 8/2/2011 |
