Urticaria
"I went to a local clinic to treat Urticaria and was given 60mg of prednisone on my cheek. It had no effect on my body and the symptoms even got worse.
Then my doctor recommended to take Benadryl (H1 blocker) and Zantac (H2 blocker) altogether. I took both pills and it made me extremely drowsy (Benadryl) and Zantac actually alleviated my symptoms just a little bit.
I woke up next morning and found out that Urticaria has come back.
Then someone recommended me to take the Allegra (Fexofenadine 180mg) and it really works without any side-effects of drowsiness.
I think Fexofenadine is god given allergy medicine. I tried Benadryl, Zyrtec and Claritin before. Their effectiveness on Urticaria is far less than Allegra."
