Yerba Mate and Abciximab

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

Moderate

ANTICOAGULANT/ANTIPLATELET DRUGS

Why this applies to Abciximab

Abciximab falls under ANTICOAGULANT/ANTIPLATELET DRUGS — the group Yerba Mate interacts with.

Theoretically, the caffeine in yerba mate may increase the risk of bleeding if used with anticoagulant or antiplatelet drugs.
Yerba mate contains caffeine. Caffeine is reported to have antiplatelet activity. Theoretically, it might increase the risk of bleeding when used concomitantly with these agents; however, this interaction has not been reported in humans.
Severity Moderate 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's the thing to know: abciximab (ReoPro) is a powerful IV antiplatelet drug given in the hospital, usually during procedures like a heart stent placement. It works by blocking platelets from clumping together, which lowers your clotting ability. The concern on file is that the caffeine in yerba mate may have its own mild platelet-slowing effect, so in theory it could add to abciximab's action and slightly raise bleeding risk (think easy bruising, bleeding gums, or oozing at an IV site).

I want to be honest about how weak this is. The evidence comes only from lab and animal studies, and this interaction has never actually been reported in people. Since abciximab is given in a closely monitored hospital setting, your care team is already watching you carefully. Still, mention any supplement or mate habit to your doctor or pharmacist.

From our pharmacist’s overview on the Abciximab page

“Because abciximab (ReoPro) exists to stop platelets from clotting during heart procedures like angioplasty, nearly all of the 218 supplements on this list pull in one direction. Some 202 have antiplatelet or blood-thinning activity of their own, and adding that on top of abciximab can raise bleeding risk.”

About Yerba Mate

What is Yerba Mate?

Yerba Mate
  • Energy and alertness
  • Weight loss
  • Mental focus
  • Digestive support
  • Antioxidant support

Yerba mate is a caffeine-containing herbal beverage from South America that is widely enjoyed for its stimulating, coffee-like effects. While it is rich in antioxidants and is being studied for weight, blood sugar, and cholesterol, strong human evidence for most health claims is limited. Drinking very hot mate over many years has been linked to higher risk of certain cancers, so enjoy it warm and in moderation.
