Fexofenadine for Allergic Rhinitis "It took me 5 years to realize Allegra was making my life a living nightmare. I have bad allergies and take it year-round. Prior to starting Allegra, I had never experienced anxiety. Overnight, I started having panic attacks. My ears started ringing all the time, and I started getting this tingling/numbing in my left arm. I also started waking up with swollen hands, feet, and face. I saw many doctors for these symptoms, I was in my mid-20s. Nobody could figure it out. I recently had been talking to a new allergist about all the issues and realized the correlation between days I take the med and waking up swollen, so I Googled the side effects. I was horrified to see the reviews!! One lady even wrote an entire article about the tingling issue. I stopped the medication immediately and am starting to feel like my old self again. I'm angry that I've been dealing with this for so long and could've stopped it had I known....."

Fexofenadine for Allergic Rhinitis "I’m a 25-year-old female whose allergies have recently decided to screw me over. I’ve been on Claritin for a couple of months now, and it works “okay.” Three days ago, I broke out with hives and went to the hospital and got prescribed Allegra. The first day I took it, it worked great! Now I’m on the second day of it, and I’m having panic attacks, anxiety, diarrhea, and dehydration. It is a shame because it does so well in treating my allergies, but I don’t think these side effects are worth it."

For Urticaria "I was prescribed fexofenadine 180 mg daily for severe itching due to eczema, but I also suffer from hay fever too. Initially worked great for the itching (I was taking it every other day at this point), however, when hay fever season started, I upped this to one tablet per day and began to experience horrible symptoms. I had heart palpitations, anxiety, and had panic attacks for weeks before I realized that it might be caused by these tablets. I also have a heart condition (mitral regurgitation) and thought this was getting worse as the palpitations were horrible, so I was very concerned. After stopping the medication, I felt better within a few days, although the anxiety did linger for a week or so. Very scary experience!!!"

For Allergic Rhinitis "Very bad experience with fexofenadine. I started getting too many side effects. I was having stomach discomfort, nightmares, heart palpitations, and panic attacks out of nowhere. I started having anxiety issues and felt very scared. Very horrifying experience. Took only 7 tablets of these (180 mg)."
