For Allergic Rhinitis "I took two 180-mg doses of Allegra for hay fever on two consecutive nights. The day after the first dose, I experienced mild, intermittent nausea and reduced appetite. The morning after the second dose, I was bedridden for 3 days with severe nausea, intermittent sweats and chills, aberrant thoughts and dreams, and a headache. I did not vomit or have diarrhea, nor did I have an abnormal temperature. As I write this on the fourth day, I am just getting up and eating a little. This was like no stomach flu I've ever had -- I feel as though I have been poisoned. I firmly believe that my illness is a side effect from the Allegra."

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 "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."
