Can I take anything like cimetidine or other h2 antagonists for allergies?

Can I take anything like cimetidine or other h2 antagonists for allergies?

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. If these are not effective I would recommend seeing an allergist and considering allergy shots. ...Read more

I bought a pack of cimetidine tablets and noticed they smell bad, like rotten eggs. Is this normal or are they off? Exp date is 8/2015.

Generic american product does not have this and is available over the counter without a prescription needed! ...Read more

Can you tell me about tagamet 300 (cimetidine)?

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

Can one drink alcohol while taking 400mg cimetidine?

Can one drink alcohol while taking 400mg cimetidine?

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

How come my son ended up getting strep 3 days after started taking cephalixen, cetirizine, and cimetidine?

How come my son ended up getting strep 3 days after started taking cephalixen, cetirizine, and cimetidine?

Confusing question: Strep is killed by cephalexin and a positive quick test would be possible because it will be so with dead germs. A positive culture would be less likely, but possible with a vigorous sampling technique. I would assume the strep was already present but additional testing confirmed it. ...Read more

How long would it take testosterone levels to return to normal after they were dropped from tagamet (cimetidine)?

Reversible: The reduction in testosterone that can occur with Cimetidine is caused by a reversible antagonism of testosterone synthesis - which means that if you are affected by this, then as soon as the drug is out of your body, your testosterone levels should return to previous levels. A level checked 2 weeks after stopping Cimetidine should be at your baseline. ...Read more

I was told by a friend of mine that certainOTC meds can boost opiate analgesics, especially us, we want relief but notincrease. Loperamide, cimetidine?

Narcotics: "Boost" here means an overall increase in pain relief through a synergistic effect of narcotics plus NSAIDS. They have different mechanisms of action. It doesn't mean that it "boosts" the narcotic mechanism of action. Loperamide IS a narcotic drug. Cimetidine is not a narc and is fine. ...Read more

Would tagamet (cimetidine) have the potential to effect a testosterone test the same day? In other. Words temporarily lower it for the test? Thanks so much

Tagamet (cimetidine) only: Affects testosterone at very high doses over a prolonged period of time. It is unlikely that one dose could lower the level enough to make the test abnormal. If there's a concern, stop the tagamet (cimetidine) and repeat the test at a later date. Talk w/your doctor. ...Read more
