Many causes: foods, chemicals, perfumes, very often stress. Stress can increase acid formation in stomach, Zantac (ranitidine) reduces it. Over 50% of time, one can't find cause.

What can I do if my doctor prescribed ranitidine for my hives and to stop the itching. Is this normal?
If a person pre-medicates w/xyzal & zantac, (ranitidine) can they take an nsaid drug, if that drug has caused minor hives in the past? Get skin reaction only.
Possibly: Both xyzal (levocetirizine) & zantac have anti-histamine effects & may decrease or eliminate a mild reaction to nsaid. However, this can be dangerous. Repeat exposures to something you are allergic to can be more severe, including breathing & swallowing difficulties, swelling of the face, lips, tongue or mouth. 6 classes of nsaids exist; you may not be allergic to other NSAID classes. An allergist may help a lot. ...Read more

Is it possible that Zantac, being a histamine blocker, could cause higher histamine production when coming off of it, resulting in development of allergies? For example consuming diet soda can result in insulin spikes in some cases, possibly leading to di
No: Zantac (ranitidine) is a histamine 2 receptor reverse agonist and would not significantly affect histamine production.when withdrawn. There is a theoretical possibility that Zantac (ranitidine) itself may lead to more histamine release by blocking the histamine 2 receptor(which acts as a feedback switch) but this has not been clinically a significant issue. ...Read more

Zantac (ranitidine) has histamine ingredients. I'm taking it recently.noticed some inverse effect,my hives is not popping out too!It should be antihistamine right?
Zantac (ranitidine): Is an antihistamine itself, it blocks H2 receptors, histamine has more than one type of receptors in the human tissues. H1, blocked by the usual antihistamines, H2, plays a role in stomach acid regulation, which zantac (ranitidine) blocks. Zantac at times is used in severe allergic reactions or severe urticaria, together with H1 blockers to control symptoms, so your deduction is right ...Read more
