Theoretically, concomitant use might have additive adverse hepatotoxic effects.
Green tea extract supplements have been linked to several cases of hepatotoxicity and might have additive hepatotoxic effects with other drugs..
Severity Moderate Likelihood Unlikely Evidence D

Interaction has been demonstrated in animal or in lab research but has been shown not to occur in humans..

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

Here's the simple version: Vyxeos (the daunorubicin and cytarabine combo used for AML) can be tough on the liver on its own. The concern with green tea is only about concentrated green tea extract supplements, which have been tied to rare cases of liver injury. Stacking two things that can stress the liver could, in theory, add up and make liver irritation more likely.

I want to be honest about the strength of this: it's theoretical and based on scattered case reports, not solid proof, and it's considered unlikely. Drinking green tea as a normal beverage is a very different thing from taking high-dose extract pills. Since your care team is already watching your liver labs closely during chemo, just let your oncologist or pharmacist know before adding any green tea supplement.

Contact Dr. Brian directly if you have additional questions on this interaction

From our pharmacist’s overview on the Daunorubicin, Cytarabine page

“Vyxeos pairs daunorubicin and cytarabine to treat acute myeloid leukemia, and its supplement list is one to handle with genuine care. Most of it points at the liver: 38 of the 50 flagged ingredients can stress an organ already processing intensive chemotherapy, and the three rated major all belong to that group.”

About Green Tea

What is Green Tea?

Green Tea
  • Antioxidant support
  • Weight loss
  • Heart health
  • Mental alertness
  • Cancer risk reduction

Green tea is a popular beverage rich in antioxidants called catechins, and drinking it in normal amounts is considered safe for most people. Concentrated green tea extracts are a different story—they may help modestly with weight or heart health for some, but high doses have been linked to rare liver problems. Talk to your pharmacist or doctor before taking green tea supplements, especially if you have liver concerns or are pregnant.
