See below: Zantac (ranitidine) is not effective for prevention of allergy symptoms. It blocks the h2 histamine receptor instead of the h1. I have seen use of both an h! and an h2 blocker for the treatment of chronic hives.

Add-on for hives: Ranitidine (zantac), although it's a different kind of histamine blocker (h2 for acid vs h1 for allergies), has been shown to have some anti-allergy properties, especially when used with an h1 blocker like Benadryl (diphenhydramine) for hives. There was actually one study that showed benefit in nasal allergies, but i don't know anyone that prescribes it for that purpose.
