Red Raspberry and Betrixaban

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

Moderate

ANTICOAGULANT/ANTIPLATELET DRUGS

Why this applies to Betrixaban

Betrixaban falls under ANTICOAGULANT/ANTIPLATELET DRUGS — the group Red Raspberry interacts with.

Theoretically, taking red raspberry leaf with anticoagulant/antiplatelet drugs might increase the risk of bleeding.
In vitro research suggests that red raspberry leaf extract has antiplatelet activity and enhances the in vitro effects of the antiplatelet medication cangrelor. 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 gist for Betrixaban (Bevyxxa), your blood thinner that helps prevent clots in your legs and lungs. The thought is that red raspberry leaf may have a mild blood-thinning quality of its own. Stacked on top of a medication that already slows clotting, the theory is that bleeding risk could go up a little. That might show up as easy bruising, nosebleeds, bleeding gums, or cuts that take longer to stop.

I want to be honest about how soft this evidence is. It comes only from lab dish studies, not from people, so it's theoretical. An occasional cup of tea is unlikely to be a problem for most folks, but if you're using concentrated supplements, mention it to your pharmacist or doctor first.
