Wine and Famotidine

Here is the interaction we found between these two, with the evidence behind it.

Moderate

H2-BLOCKERS

Why this applies to Famotidine

Famotidine falls under H2-BLOCKERS — the group Wine interacts with.

Concomitant use might increase blood alcohol levels and adverse effects.
Concomitant use of the H2-blockers cimetidine and ranitidine with low doses of alcohol (0.15 grams/kg) might increase blood alcohol levels and adverse effects. Effects with higher doses of alcohol (0.3-1.5 grams/kg) are variable.
Severity Moderate Likelihood Possible Evidence C

Interaction has been documented in animal or in lab research, or the interaction has been documented in humans but is limited to case reports or conflicting clinical research exists.

Dr. Brian Staiger, PharmD, BCPS
Dr. Brian Staiger explains PharmD, Clinical Pharmacist

Here's the gist for famotidine (Pepcid) and a glass of wine. H2 blockers can slightly slow how your stomach breaks down alcohol, so a little of the alcohol may pass into your blood instead. The result is that a given amount of wine might hit you a touch harder than usual. This effect was mainly studied with older H2 blockers like cimetidine and ranitidine, the evidence is based on expert consensus, and with larger amounts of alcohol the findings were mixed.

In real life this tends to be modest. Famotidine itself isn't strongly affected, but you might feel the alcohol a bit more. If you drink, keep it moderate, and check with your pharmacist if you have questions.

See Every Supplement That Interacts With Famotidine

This page covers Wine only. If you take other supplements — a multivitamin, a sleep aid, something for joints — the Famotidine page lists 41 supplements it has a documented interaction with, worst first, each one explained.

The most serious there right now: Activated Charcoal (major), African Wild Potato (moderate), Banderol (moderate), Beer (moderate) and Biofeedback (moderate).

By severity: 1 major · 19 moderate · 21 minor.

From our pharmacist’s overview on the Famotidine page

“Famotidine (Pepcid) treats heartburn and acid reflux, a low-stakes job most days, but its interaction list earns genuine caution because one entry is rated major. That entry is activated charcoal, which can bind famotidine in the gut and sharply cut how much of the drug reaches your blood.”

About Wine

What is Wine?

  • Social and relaxation use
  • Heart health (popular belief)
  • Antioxidant intake
  • Aiding digestion (traditional use)
  • Culinary flavoring

Wine is an alcoholic beverage made from fermented grapes and is not a true dietary supplement or medicine. Despite popular claims about heart benefits, the alcohol it contains carries real health risks, and no amount of drinking can be recommended to improve health. If you drink, do so in moderation, and avoid alcohol entirely during pregnancy or if you have certain medical conditions.

About Famotidine

What Is Famotidine Used For?

Brand names: Pepcid, Famotidine, Pepcid AC, Famotidine Injection

Famotidine treats a range of acid-related conditions. Over-the-counter tablets (such as Acid Controller, Acid Reducer, Acid Relief, Amazon Basic Care Acid Reducer, Basic Care Acid Reducer, and Calmicid AC) relieve and prevent heartburn associated with acid indigestion and sour stomach.

Prescription-strength famotidine tablets and oral suspension are used for active duodenal ulcers (ulcers in the small intestine), active gastric ulcers (stomach ulcers), GERD — including erosive esophagitis (inflammation that damages the esophagus), and pathological hypersecretory conditions such as Zollinger-Ellison syndrome (a rare disorder causing the stomach to produce too much acid). The oral suspension is also indicated in children as young as newborns for GERD, and in children one year and older for peptic ulcer disease. Famotidine injection is used in hospitalized patients who cannot take oral medication.
