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

Here's the thing about rifampin: it's already known to be tough on the liver. That's a normal, expected part of how this TB medicine works in your body. When you add beer to the mix, you're asking your liver to handle two stressors at once, and that combination can raise your chances of liver injury.

Watch for signs your liver isn't happy, like yellowing of the skin or eyes, dark urine, belly pain on the upper right side, unusual tiredness, or nausea that won't quit. An occasional small drink may be lower risk than heavy or regular drinking, but honestly, the safest move during rifampin treatment is to skip alcohol entirely. Please check with your doctor or pharmacist before having any beer while you're on this medication.

About Beer

What is Beer?

Beer
  • Social and recreational drinking
  • Relaxation
  • Heart health (popular belief)
  • Bone health (popular belief)
  • Source of antioxidants and B vitamins

Beer is an alcoholic beverage that contains some minerals, B vitamins, and plant compounds from hops and grain, but it is not a health supplement. Any possible benefits come only from light-to-moderate intake, and they are easily outweighed by the well-known harms of alcohol. The safest amount of alcohol for health is none, and beer should be avoided in pregnancy and breastfeeding.

About Rifampin

What Is Rifampin Used For?

Brand names: Rifadin, Rimactane, Rifadin Injection, Rofactor

Rifampin treats all forms of tuberculosis (TB). It is almost always used in combination with other antibiotics — your doctor will build a multi-drug regimen tailored to your infection. Treatment usually runs for at least 6 months total.

Rifampin is also used to clear Neisseria meningitidis bacteria from the nose and throat in people who carry the germ without being sick themselves. It is not used to treat active meningococcal disease. The intravenous (IV) forms — Rifadin IV, Rifadin IV NOVAPLUS, and the injectable form of Rifampin — are specifically indicated when a patient cannot take the drug by mouth.
