Beer and Ritonavir

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

HEPATOTOXIC DRUGS

Why this applies to Ritonavir

Ritonavir falls under HEPATOTOXIC DRUGS — the group Beer interacts with.

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 B

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 deal with Ritonavir (Norvir) and beer. Ritonavir is processed by your liver, and on its own it can be tough on liver cells. Alcohol is also hard on the liver. When you regularly add beer on top of this medication, you're asking your liver to handle two stressors at once, which can raise your risk of liver injury. Watch for warning signs like yellowing of the skin or eyes, dark urine, belly pain on the upper right side, unusual tiredness, or nausea.

An occasional drink is different from heavy or daily drinking, where the concern is greatest. Please don't change your HIV medication on your own. Have a quick chat with your doctor or pharmacist about what amount of alcohol, if any, is safe for you, since they may also want to check your liver labs.

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.

Brand name: Norvir

Ritonavir (brand name Norvir) is used together with other HIV medicines to treat HIV-1 infection in adults and children older than one month of age. It is always taken as part of a combination regimen — never on its own.

Ritonavir tablets (generic) are also indicated for the treatment of HIV-1 infection in combination with other antiretroviral agents.
