Chrysin and Ibrutinib

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

Moderate

ANTICOAGULANT/ANTIPLATELET DRUGS

Why this applies to Ibrutinib

Ibrutinib falls under ANTICOAGULANT/ANTIPLATELET DRUGS — the group Chrysin interacts with.

Theoretically, chrysin might increase the risk of bleeding when taken with anticoagulant or antiplatelet drugs.
In vitro evidence suggests that chrysin might inhibit platelet aggregation.
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 explains PharmD, Clinical Pharmacist

Here's the situation with ibrutinib (Imbruvica) and chrysin. Ibrutinib already carries a known bleeding risk on its own, because it affects how your platelets stick together. So even minor cuts, bruising more easily, nosebleeds, or bleeding gums can show up in people taking it.

Chrysin's concern here is purely theoretical. In test-tube studies it appeared to slow platelet clumping too, so stacking it on top of ibrutinib could, in theory, add to that bleeding tendency. There's no solid human evidence this actually happens, and chrysin is poorly absorbed by the body. Still, with a serious cancer medication like this, I'd play it safe. Please check with your oncologist or pharmacist before adding chrysin, and watch for any unusual bruising or bleeding.

From our pharmacist’s overview on the Ibrutinib page

“Ibrutinib (Imbruvica) treats blood cancers such as chronic lymphocytic leukemia, and because the drug itself makes bruising and bleeding more likely, adding the wrong supplement here can carry real consequences. Most of the entries below have blood-thinning or antiplatelet activity that stacks on top of that built-in bleeding risk.”

About Chrysin

What is Chrysin?

  • Bodybuilding and testosterone support
  • Anxiety and stress
  • Anti-inflammatory
  • Antioxidant support
  • Prostate health

Chrysin is a plant flavonoid sold mainly as a bodybuilding supplement claimed to raise testosterone or block estrogen, but human studies have not shown these benefits, largely because the body absorbs very little of it. Evidence for its other proposed uses is mostly limited to laboratory and animal research, so its real-world value is unclear. Talk with your pharmacist or doctor before using it.
