allergic urticaria
"I took Zyrtec everyday for a month and saw zero improvement with my sudden outbreak of hives. Then I was advised to take double doses of Zyrtec AND Allegra. Only thing I got was sleepy. I've been taking Famotidine for three days. I saw almost immediate results. Today is day 3, and all my hives are gone. The itching is virtually gone. Even the dark spots the hives were leaving behind before seem to be fading. I haven't noticed any side effects except my extreme joy that something finally worked!"
