Wine and Sulfadiazine, Trimethoprim

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

Moderate

SULFONAMIDE ANTIBIOTICS

Why this applies to Sulfadiazine, Trimethoprim

Sulfadiazine, Trimethoprim falls under SULFONAMIDE ANTIBIOTICS — the group Wine interacts with.

Concomitant use may cause a disulfiram-like reaction.
Sulfonamide antibiotics can cause a disulfiram-like reaction when taken with alcohol.
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

If you're taking Coptin (the sulfadiazine and trimethoprim combo) and you have a glass of wine, there's a chance you could feel pretty lousy. Some sulfonamide antibiotics like sulfadiazine can trigger what we call a disulfiram-like reaction when mixed with alcohol. That can mean flushing, a pounding headache, nausea or vomiting, a racing heart, and feeling dizzy or unwell.

This doesn't happen to everyone, and the evidence here is based more on expert consensus than strong studies, so I don't want to scare you. Still, it's an easy one to sidestep: it's reasonable to skip the wine while you're on this antibiotic and for a short time after you finish. If you're unsure, your pharmacist or doctor can give you the green light for your situation.

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.
