Interaction report

Wine and Diclofenac Potassium

These two interact in 2 distinct ways. Each one is explained separately below.

Why Are There 2 Interactions?

Wine interacts with whole categories of medication. Diclofenac Potassium falls into 2 of those categories, so it can interact with Wine in 2 different ways. We’ve listed each one below — your overall risk is driven by the most serious of them (Major).

Major

NONSTEROIDAL ANTI-INFLAMMATORY DRUGS (NSAIDs)

1 of 2

Why this applies to Diclofenac Potassium

Diclofenac Potassium falls under NONSTEROIDAL ANTI-INFLAMMATORY DRUGS (NSAIDs) — the group Wine interacts with.

Concomitant use may increase the risk of gastrointestinal (GI) bleeding.
Concomitant use of NSAIDs with alcohol may increase the risk of GI bleeding.
Severity Major Likelihood Probable Evidence C

Interaction has not been documented in well-controlled studies, however, the interaction has been demonstrated in some small human studies or in controlled animal studies in conjunction with multiple case reports..

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

Here's the thing to keep in mind: diclofenac, like other NSAIDs, can be tough on your stomach lining. It works by blocking chemicals that normally protect that lining, which is why heartburn, stomach upset, and even bleeding can happen. Wine adds to that irritation. Alcohol itself can wear down the stomach's protective barrier, so when you pair the two, the risk of a bleed in your stomach or gut goes up.

This isn't about how diclofenac is broken down, it's a direct double-hit on your stomach. Watch for warning signs like black or tarry stools, vomit that looks like coffee grounds, or stomach pain that won't quit. An occasional glass with food is lower risk than regular or heavy drinking, but please talk with your pharmacist or doctor about what's safe for you.

HEPATOTOXIC DRUGS

2 of 2

Diclofenac Potassium also falls under HEPATOTOXIC DRUGS.

Concomitant use of alcohol with hepatotoxic drugs may increase the risk of hepatotoxicity.
Concomitant use of excessive amounts of alcohol with potentially hepatotoxic drugs can increase the risk of liver damage.
Severity Major Likelihood Probable Evidence C

Interaction has not been documented in well-controlled studies, however, the interaction has been demonstrated in some small human studies or in controlled animal studies in conjunction with multiple case reports..

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

Here's the plain version: diclofenac is one of those pain relievers (an NSAID) that your liver has to work to process, and in some people it can stress the liver. When you add alcohol from wine into the mix, you're asking the liver to handle two things that can both be hard on it. The concern here is added strain on the liver, not a change in how well the diclofenac eases your pain.

This matters more with regular or heavy drinking than with an occasional small glass. Watch for warning signs like unusual tiredness, nausea, pain in the upper right belly, dark urine, or yellowing of the eyes or skin. As a bonus reminder, both alcohol and diclofenac can irritate the stomach, so combining them also raises the odds of stomach upset or bleeding. Please check with your pharmacist or doctor about what's safe for you.

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.
