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."

For Allergic Rhinitis "I've tried other allergy medications, but Allegra-D is the only one that works. I used to get constant post-nasal drip and have to clear my throat all the time. On this medication, I feel amazing. It does, however, cause insomnia and bad dry mouth. It also makes it so I don't get a full erection. So do I feel better and not have sex, or what?"

For Allergic Rhinitis "Allegra D is the best medicine for my allergies, and I've taken just about every over-the-counter medicine. I have terrible hay fever, and I'm allergic to almost all grasses, trees, and pollen in my region (Midwest - Illinois). My allergist suggested that I move to Arizona. Unlike Allegra D 12-hour, I'm having trouble with side effects: insomnia, nausea, heartburn, cramping. The stomach-related effects are beginning to taper off, but the insomnia isn't."

"I'll never take this again. I took this twice. Decrease in allergies, but I would rather deal with allergies than the horrible side effects. This drug made me an emotional wreck both times, extreme insomnia, and had vivid dark, self-harming thoughts, even though I am a very happy person. Also, I was very nauseous. I can't believe this stuff is available over the counter."

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."

For Allergic Rhinitis "I only take this in my extreme cases where my congestion gets so bad I can't breathe; I never take this daily. Within an hour, I feel better. It does do a bit of insomnia, but that's usual for me."

For Allergic Rhinitis "This is the only medicine that works for my allergies. I get horrible allergies, so miserable I can't breathe. This medication helps me a lot, but I have trouble sleeping."
