Why am I itching???????

Interesting. I've always thought of Zantac as an ulcer medication (a proton pump inhibitor? my brain is rusty), rather than an antihistamine.

It is a heartburn/ulcer med but it is an H2 antihistamine, not a PPI. Things like Benadryl and Claritin are H1 antihistamines. I think the use of the H2 blockers for allergies is a somewhat new use (not an approved indication that I know of, but I'll look and see.) From what I read it looks like it is usually only recommended when the allergic reaction is hives. Again, just a quick look at this point. I'm a Dr of Pharmacology and someone who, as my mother always said came out of the womb with allergies, and yet I hadn't heard of docs using ranitidine for allergies.
