Fexofenadine for Allergic Rhinitis "Allegra stops the drainage and the annoying need to clear my throat (post nasal drainage). But I'm dizzy these last couple of weeks since I've started it. I have a mild sore throat and headache, which I experienced previously when trying Allegra. I feel tired, nauseous, and have had a strange tingling in my legs occur twice this week. I'm thinking Allegra is not a good choice for me, despite its effectiveness."

Fexofenadine for Allergic Rhinitis "I took two 180-mg doses of Allegra for hay fever on two consecutive nights. The day after the first dose, I experienced mild, intermittent nausea and reduced appetite. The morning after the second dose, I was bedridden for 3 days with severe nausea, intermittent sweats and chills, aberrant thoughts and dreams, and a headache. I did not vomit or have diarrhea, nor did I have an abnormal temperature. As I write this on the fourth day, I am just getting up and eating a little. This was like no stomach flu I've ever had -- I feel as though I have been poisoned. I firmly believe that my illness is a side effect from the Allegra."

Fexofenadine for Allergic Rhinitis "I have had a lot of trouble finding a newer antihistamine that works well for me. I have tried all the 24-hour ones, and Allegra seemed to be the right fit, but I had to stop taking it when I noticed yucky side effects. I realized that it was causing GI issues, such as abdominal cramps, nausea, and diarrhea. I was also getting dizzy spells out of the blue. When I don't take the Allegra, I'm fine. It's a catch-22 because it does seem to help with my post-nasal drip, but it's not worth having GI issues over."

For Allergic Rhinitis "For the first time in well over 10 years, I stood in a field of grass today on a day forecast as “very high grass pollen.” I haven’t sneezed once, my eyes have watered maybe a couple of times. I was classified as “class 5 of 6” allergy (unsure of what scale) by my previous GP and trialed on Grazax, unfortunately, that wound up not suiting after a wisdom tooth extraction. Throughout the years, my former GP gave various steroid nasal sprays and antihistamines. I tried Prevalin, which worked decently well. All of this is irrelevant, however, as my new GP gave me Telfast 1x120mg fexofenadine tablets and an Avamys nasal spray this year in May, and I am in disbelief with how well it is working. No major exhaustion, possibly some very mild nausea. But for me personally, this has been a life-changing experience. I’m now alive the entire year, not just half of it. I would hope everyone can find the level of relief I’m feeling."

For Allergic Rhinitis "Awful! Absolute nightmare and bad side effects! I had to stop it after 4 days due to severe side effects. Made me very ill. It is non-drowsy, however, I felt severe heartburn, nausea, flu-like symptoms, chills, weakness. Furthermore, it stopped working after 18 hours."

For Allergic Rhinitis "33 years old male living in central Texas. Fexofenadine is extremely effective in eliminating hay fever and allergic symptoms, however, the problem comes with its side effects. Even with 45 mg per day, I'm still experiencing obvious nausea, but it still eliminated the hay fever. Only took the medicine for a week, recommended for a try, but wouldn't continue if you don't like the side effects."

For Allergic Rhinitis "This medication didn't work for me. After a few days of taking it, I had a headache, back pain, nausea, a sore stomach, and poor appetite. I have gone back to over-the-counter medication."

Fexofenadine for Allergic Rhinitis "So, my body has a very high natural histamine level, which means that I will break out in hives with feet and hand swelling almost every day. There’s no cause, my histamine levels tend to just be high. A long time ago, my sister used to use this medicine for the same condition. Therefore, when I started breaking out, my mom recommended this to me. As soon as I started taking it, it was truly a miracle. It works so quickly and efficiently to relieve my hives and remove the swelling to allow me to be able to walk on my feet properly. I have zero side effects. It’s just a medicine that does its job: no drowsiness, no nausea. I accidentally double-dosed once, and not a single problem happened. It’s an incredible medicine. I’m thankful for Allegra/fexofenadine."
