What is pepcid (famotidine)?

Acid reducer: Histamine 2 receptor blocker, which decreases production of stomach acid. This allows for healing of inflammation in duodenum, as stomach, and esopha. Not as potent as ppi drugs like prilosec, which inhibit proton pumps in the stomach to further decrease production of acid.

Will expired Pepcid (famotidine) still be effective?

Will expired Pepcid (famotidine) still be effective?

Yes: Most medicines may still work years after the expiration date, but the effect may be weak or unpredictable. There are few medications that never should be taken after the expiration date (example : : tetracyclines. Avoid liquid antibiotics, insulin, & nitroglycerine).If the expiration date passed a few years ago and it's important that your drug is absolutely 100% effective get a new bottle.

Went to er, I have stomach ulcer and low potassium. Was prescribed Pepcid (famotidine) and potassium. Still have chest pains randomly. What could it be caused by?

Need more info: Chest pain may be due to musculo-skeletal cause, acid reflux, lung or heart disease, esophageal disease and more. It would require taking a detailed history, physical examination may be some tests. It would be prudent to see a primary care doctor for an evaluation. If you are overweight, it would help to lose weight.

Safe to take Pepcid (famotidine) AC (20mg) daily? Works wonders for me. Concerned about long-term effects the medication might have on me however.

Check with MD: As to why you need to be on any antireflux/acid reducing medicine. Rule out problems that might occur over thr long term; address other issues re: weight, meds, alcohol, diet, tobacco, that may affect reflux and GERD. Lowest dose of least potent med for shortest period of time to do the job is a reasonable approach. Chronic reflux canlead to problems, including esophageal cancer. See MD

Alcohol: In general will rev up your liver metabolism, thereby reducing efficacy of certain medications, while other times it may increase their toxicity. Use good judgment and moderation always.

Are confusion and seizures side effects of pepcid (famotidine)?

Are confusion and seizures side effects of pepcid (famotidine)?

Can be: Pepcid (famotidine) and other acid-suppression drugs (ppis) are commonly used, for long periods of time for various stomach conditions - and not always needed. First, almost any side effect can happen with almost any drug, and each person can have their "own" side effect. In general however, seizures are very uncommon with ppis but can happen. Confusion is a little more common esp in older folks.

How does Pepcid (famotidine) AC interact with alcohol? Is it ok to consume both at the same time?

How does Pepcid (famotidine) AC interact with alcohol? Is it ok to consume both at the same time?

Not good idea: In general, one should not take alcohol with medications. If you have to take pepcid, (famotidine) I would be concerned for possible gastritis and sometimes even ulcers as alcohol can be a causative factor. Best is to avoid alcohol for a while and let your stomach calm down. If symptoms persist, you may need to see a gastroenterologist. Of course, your liver will also thank you.

Yes: An enlarged liver can cause pain. The MD was probably thinking Peptic Ulcer Disease and Rx the Ancef/Pepsid. You need to see a Gastroenterologist for the cause of the Hepatomegaly and get a full diagnostic w/u
