Wine and Bupropion, Naltrexone

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

Moderate

BUPROPION (Wellbutrin)

Theoretically, concomitant use may increase the risk of adverse effects from alcohol.
In patients taking bupropion, there have been rare reports of adverse psychiatric events or reduced alcohol tolerance. Additionally, in chronic alcohol users, abrupt discontinuation of alcohol while taking bupropion may increase the risk of seizure.
Severity Moderate Likelihood Possible Evidence D

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 explains PharmD, Clinical Pharmacist

Here's the practical picture with Contrave (the bupropion and naltrexone combo) and wine. Bupropion can lower your seizure threshold, and that risk goes up if you drink heavily and then suddenly stop. There are also rare reports of people having a harder time tolerating alcohol on bupropion, meaning a glass might hit you differently than expected, or you might notice mood or behavior changes. Naltrexone, the other half, doesn't mix well with alcohol either since it blunts the reward feeling.

This is based mostly on anecdotal reports, not strong studies, so I'm not trying to scare you. Still, the safest move is to limit or avoid alcohol on Contrave. Please check with your pharmacist or doctor about what's right for you.

From our pharmacist’s overview on the Bupropion, Naltrexone page

“Anyone taking Contrave (bupropion with naltrexone) for weight management should treat this list with genuine care, starting with the single major-rated entry, activated charcoal, which can soak up the medication in the gut and sharply blunt its effect. Beyond that, two themes dominate.”

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.
