Kombucha and Disulfiram

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

Minor

DISULFIRAM (Antabuse)

Theoretically, kombucha might cause a disulfiram reaction when taken with disulfiram.
Kombucha products can contain up to 3.6% alcohol.
Severity Minor 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, PharmD, BCPS
Dr. Brian Staiger explains PharmD, Clinical Pharmacist

Here is the thing to keep in mind with disulfiram (Antabuse): it works by making your body react badly to any alcohol, even tiny amounts. The catch with kombucha is that fermentation produces a little bit of alcohol, sometimes up to around 3.6%. So in theory, drinking it while on disulfiram could trigger that classic reaction: flushing, headache, nausea, a racing heart, or feeling sweaty and unwell.

This is a theoretical concern based on the alcohol content, not strong human studies, and many commercial kombuchas are quite low in alcohol. Still, since disulfiram is designed to react to even small traces, I would not risk it. Please check with your pharmacist or doctor before mixing the two.

About Kombucha

What is Kombucha?

  • General wellness and gut health
  • Digestion
  • Immune support
  • Energy and detox claims
  • Source of probiotics

Kombucha is a fermented tea that many people enjoy as a probiotic-rich beverage, but solid human research proving specific health benefits is lacking. It is generally fine in moderate amounts for healthy adults, though homemade or unpasteurized versions can carry contamination risks. Pregnant people, those who are breastfeeding, and people with weakened immune systems should be cautious or avoid it.

About Disulfiram

What Is Disulfiram Used For?

Brand name: Antabuse

Disulfiram is used as part of a treatment program for people with chronic alcoholism who want to stop drinking. It works by making the body react very unpleasantly to alcohol, which helps reinforce the commitment to stay sober.

It is not a cure for alcoholism, and it works best when combined with counseling, motivation, and support. Used alone, without those supports, it is unlikely to make a lasting difference.
