Fexofenadine / pseudoephedrine for Allergic Rhinitis "This medication is NOT recommended! I have severe allergies to the spring weather, and since nothing else was working for me, I decided to try this. At first, it was like magic, my allergies went away, no itchy eyes, no sore throat, I felt great! The side effects really hurt me, though. It was about two days after taking the medication that I suffered a 24-hour migraine along with flu-like symptoms, high fever, rashes, dizziness, confusion, racing heart, chills, anxiety, nausea, dry mouth, sleep problems, loss of appetite, and ringing in my ears. It has been the worst two days of my life thanks to this medication."

Fexofenadine / pseudoephedrine for Allergic Rhinitis "I tried Allegra D 24 as my pharmacy was out of Claritin D. The 1st few days this really didn't do anything for my sinuses, by day 7, I was suffering from such intense side effects that I could not work and wound up with an emergency appointment with any doctor that would see me at my doctor's office. My side effects from Allegra D were anxiety to the 10th power (never had anxiety before), chest tightness, felt like my throat was closing, could not breathe, terrible cough, dry mouth. It has been a horrible few days while waiting for this medication to leave my system. I was even given Xanax to help relieve my anxiety, which, if you have taken it, is no picnic either. I have been taking Claritin D for years and never experienced anything like this."

For Allergic Rhinitis "Allegra-D (24 hour) does relieve my nasal symptoms very quickly, and the relief lasts a long time. The downside of this medication for me is that it increases my anxiety drastically. I lose my temper and overreact concerning the slightest things. When I came off of it, I returned to my normal self and began to enjoy life again. When I decided to go back on Allegra, I began to suffer from the same side effects. So I know it's the medication."

Fexofenadine / pseudoephedrine for Allergic Rhinitis "I had a terrible ear infection, even after using a full Z-pack. Went back to urgent care, and the Dr. gave me another antibiotic and told me to get an ENT, as she could only do so much. I booked an appointment with an ENT and was able to get in fairly quickly. The doctor told me to use Allegra D and Flonase for my ear infection. Frankly, I found it bizarre (I don't know if it's indicated for ear infections) but, trusting him, I bought the Allegra. It came with only ten tablets, and apparently that's the largest size my pharmacy had. I also found that weird, as they are never out of ephedrine HCl, which I use for asthma. The first thing I noticed was the *240mg* of pseudoephedrine, which is a massive dose. I hate pseudoephedrine, but this was surprisingly smooth. All I noticed was slight irritation and anxiety. I wouldn't want to take it again, but would if I needed to. It seemed to work decently for my ear, though I feel I still have an infection."

Fexofenadine / pseudoephedrine for Allergic Rhinitis "Efficient for allergies, but bad side effects. I experienced many of them: ringing in my ears, insomnia, unusual behavior, anxiety, unable to concentrate, itchy skin, and a couple more."
