Can Pepcid (famotidine) AC to help alcohol allergy?

Can Pepcid (famotidine) AC to help alcohol allergy?

See below.: You cannot be allergic to alcohol - that is impossible. You can only be allergic to things that have proteins. Alcohol chemically has no proteins. You may be sensitive to alcohol. For example, it may give you heart burn. If that is the case, Pepcid (famotidine) may help but I would not advise that. Rather, i'd advise not using alcohol at all or limiting the amount and frequency so it doesn't affect you longer. ...Read more

Is there any over-the-counter acid reflux medicine stronger than Pepcid (famotidine) complete and prilose otc?

Is there any over-the-counter acid reflux medicine stronger than Pepcid (famotidine) complete and prilose otc?

Sure...: Pepcid (famotidine) is an H2 blocker. That class of drugs relative to acid suppression is exceeded by the proton pump inhibitor (PPI) class, of which Prilosec was the first. Many subsequent PPI's have been introduced with longer durations of action. Although we can't endorse particular products on HealthTap, ask your pharmacist to recommend another PPI. Better yet, see your gastroenterologist for the right Rx. ...Read more

Can Pepcid (famotidine) be taken with cold medicine? Taken over-the-counter cold meds, liquid and pills, but have really bad heartburn.

Can Pepcid (famotidine) be taken with cold medicine? Taken over-the-counter cold meds, liquid and pills, but have really bad heartburn.

It's OK: Pepcid is a type of histamine blocker that is not found in any cold products. You need to be careful with cold meds because they have multiple ingredients. I advise my patients to take only OTC meds that have 1 ingredient! If you need pain relief - take ibuprofen. If you need cough suppressant - take robitussin (guaifenesin). If you need decongestant - take sudafed. Even I get confused in that aisle!!! ...Read more

Can I take 4 pepcid complete through out the day? My regular doctor said I can take 3 but didn't ask about 4

Can I take 4 pepcid complete through out the day? My regular doctor said I can take 3 but didn't ask about 4

May get diarrhea: Pepcid Complete is a combination of Famotidine, calcium carbonate and magnesium hydroxide. You could safely take 4 times the dose of the famotidine and calcium carbonate, however more than 1200mg of magnesium hydroxide "may" cause diarrhea. Each pepcid complete has 400mg magnesium hydroxide, which is why your Dr said you could take 3 but not 4. If you are constipated, then go ahead and take 4! ...Read more

Which is associated with more/less possible adverse health effects from long term use? Prilosec or pepcid (famotidine)?

Heartburn meds: Both PPI's, such as Prilosec, and H2-blockers, such as Pepcid, (famotidine) are frequently used medications for Gerd. Both of these classes of medicines are reasonably safe, and if needed can be used long-term generally very safely. If you have severe symptoms, I would not shy away from using whichever controls your symptoms the best. Be sure to follow anti-reflux precautions! Good luck. ...Read more

Don't combine them: If your symptoms are so severe you're considering doubling up on acid blockers, you need medical evaluation. Please see your physician asap. It looks like you've already had endoscopy, so you already have a gastroenterologist who knows your case. Please contact this physician for more individualized advice -- and you might consider a good probiotic and some Tums (calcium carbonate) in the meantime. ...Read more

Pepcid (famotidine) AC is not helping my heartburn, is there another OTC I can take? Would taking it every 12 hours help?

Is it really GERD?: Yes, Prilosec otc is stronger but gerd can be due to diseases that impair esophageal function, cause inadequate saliva, gastric outlet narrowing, gastroparesis, small bowel pathology, etc. Damage from inadequate treatment may result in esophageal ulcers, scarring, narrowing, pre-cancer (barretts).
