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."

For Allergic Rhinitis "I have had bad allergies my entire life and was given many different medicines to try. This is the first medicine that actually worked for me. I took one 24-hour dose yesterday at 4 pm, and today at 10 am my nose is still clear. The only problem I had was that my blood pressure spiked up to 146/93 from a normal range of 120/70. During that time, I had a terrible headache and felt extremely dizzy. I went to bed and woke up to recheck my blood pressure. It was still elevated at 127/86, and I still have a slight headache, but I can breathe."

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 "It worked very well for my allergies, but the problem was I couldn't function due to extreme dizziness, to the point of vomiting. I cannot take it, so I'm taking Zyrtec."
