European Barberry 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 European Barberry interacts with.

Theoretically, European barberry may increase the risk of bleeding if used with anticoagulant or antiplatelet drugs.
In vitro and animal evidence suggest that berberine, a constituent of European barberry, might inhibit platelet aggregation. Theoretically, European barberry might have a similar effect.
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 thing to know about abciximab (ReoPro): it's a powerful clot-blocker given through the vein, usually in a hospital during heart procedures like stenting. Its whole job is to stop platelets from clumping together, which lowers your clotting ability on purpose.

European barberry contains berberine, and in lab and animal studies berberine also seems to make platelets less sticky. So in theory, pairing the two could nudge your bleeding risk a little higher (think easier bruising, bleeding gums, or oozing at an IV or catheter site). I'll be honest though, this concern is theoretical only, based on test-tube and animal data, not real patient cases. Since abciximab is hospital-given, your care team is already watching you closely. Still, always tell them about any supplements you take.

By severity: 3 major · 190 moderate · 25 minor.

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 European Barberry

What is European Barberry?

European Barberry
  • Digestive upset
  • Antimicrobial support
  • Blood sugar support
  • Cholesterol and metabolic support
  • Skin conditions

European barberry is a shrub whose root, bark, and berries contain berberine, a bitter plant alkaloid that has been studied mostly in isolated form. Some early research on berberine is promising for blood sugar and cholesterol, but high-quality evidence for the whole barberry herb is limited. Talk with your pharmacist or doctor before using it, and avoid it during pregnancy and breastfeeding.
