Medicine For Cimetidine Allergy
Not for allergies: H2 antagonists partially block acid secretion in the stomach. They don't do much (if anything) for allergies. I would use either oral H1 antihistamines (zyrtec, Allegra etc.), nasal sprays or eye drops.

Stomach acid reducer: Tagamet (cimetidine) is one of the older drugs used for stomach and duodenal ulcers. Before tagamet (cimetidine) persons on occasion had to have part of their stomach surgically removed to treat ulcers. Tagamet (cimetidine) significantly reduced stomach acid production allowing the ulcer to heal. It is not quite as strong for a better word as say Prilosec which blocks all acid production but at a low cost tagamet (cimetidine) 300 may be just fine. ...Read more

Caution: Cimetidine can impair your body's ability to break down alcohol, which means that you could get drunk on smaller amounts of alcohol than you normally would. Also, alcohol often worsens diseases for which you may be taking Cimetidine in the first place. I would avoid alcohol, but if the alcohol is important to you, you may want to be on a different stomach medicine. Good luck. ...Read more
