 1  Severe allergies I have taken Allegra D before and felt horrible. So I thought taking the regular Allegra would be okay. I was wrong! I feel the same way when I took the Allegra D. My whole body aches, feverish, exhausted. I feel like I have the flu. Never again! F 32 1 days

 4  Year round allergic asthma Seem to be more prone to head colds. But trade off was OK if you want to breath. This year was really bad for allergies causing a lot of sneezing, wheezing and tightness. But Allegra really helped out. For me it took about a week or so to kick in but after that, I could honestly tell the difference. Zyrtec actually worked faster & better but it was much more sedative than Allegra and couldn't function during the day. Allegra on the other hand had absolutely no sedative effects on me. It's not a 100% fix - more like 75% but I'll take it and I think it would be a little bit safer than Singulair. M 56 6 months

 1  Severe Allergies I really thought I was feeling under the weather because of my allergies which made sense to me but it was the Allegra. I felt dizzy, I felt weak, and totally out of it. I would take it in the morning and by 3 p.m. I would be completely out of it, shaky and kind of disoriented. It did not occur to me that it could be the Allegra because I had taken it once before and I was fine but then just to be sure I searched and found out that countless people felt the same exact thing as me. I will be stopping immediately M 51 2 weeks

 1  Allergies Crying, Depression, Fear of so many things. Worrying uncontrollably. In consolable. Can't sleep. Very sad and miserable. Unmotivated. Wants to quit extracurricular activities. This is for my daughter. She has the allergies and right now after reading all of this I would like to give the damn paediatrician a piece of my mind. She is bloody 9 yrs old. Why were we not told about this as a side-effect. I did not study for so many years and I can say YOU DO NOT GIVE THIS TO ANY CHILD!!!!!! Its absolutely ridiculous. I've read up about the 1st and 2nd and 3rd generation antihistamines. They tend to warn you off the first generation ones. But we have never experienced anything as drastic as this in an antihistamine, a 3rd generation. Here they call it Telfast, not Allegra. F 9 2 months

 1  Seasonal Allergies Fogginess, short term memory loss, nausea, lower back pain, leg pain, daily headaches, severe exhaustion, water rushing in my ears, yeast infection? At first I thought it was great because the seasonal allergy symptoms almost completely subsided. However, I noticed right away I couldn't remember passwords or number sequences that I use all the time. I also, would go to do something and could not remember what it was right away. I thought it was because I have been exercising and eating low calorie diet. I started getting headaches last week in the afternoons like clock work and by the time I got home from work I was extremely exhausted. I just chalked this up to allergies though, but there was other odd things I noticed. I kept having water rushing in my ears and then I started to (TMI) get a random yeast infection. That was the last straw that brought me to this feed and I am shocked to read all these experiences. I am quitting cold turkey right now and switching to local honey and Nettie pots! This is crazy!

 1  Seasonal allergies Depression, extreme anxiety, lowered sex drive, personality change, and the worst case of constipation. I started taking Allegra at the start of allergy season, and immediately I started to have an extreme uneasy feeling. My sex drive is practically nonexistent at the moment and I haven't pooped in 5 days! I feel like I have a higher heart rate, and a general unwillingness to do anything. This being day five of no bowel movement and feeling bloated and backed up, I researched the side effects and to no surprise constipation has been reported. I'm stopping immediately and hoping I'll get back to my happy, active, REGULAR self. 10/10 don't recommend. F 20 8 days
