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 "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."

For Allergic Rhinitis "This medication works great for allergies. My mom takes it, and she loves it. However, as soon as I take it, I start feeling all those crazy side effects: dizziness, nausea, pain everywhere, headaches, crying spells, etc. I personally won’t ever take it again because it is definitely NOT for me, but it is for people like my mom. So I don’t know. Maybe it just depends on your body because everyone is different."

For Allergic Rhinitis "Do NOT take this medicine. It should be illegal. I took it for 3 days, and all 3 days I felt nauseous, dizzy, unmotivated, and depressed. The worst part is I haven’t slept more than 2-3 hours a night. This medication will disrupt your life. I usually take Zyrtec D but decided to try Allegra out - my allergies have gotten exponentially worse on it. I have had severe sinus pressure, a cough, and headaches in addition to all the other symptoms."

"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."
