Eicosapentaenoic Acid (epa) 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 Eicosapentaenoic Acid (epa) interacts with.

Theoretically, EPA may increase the risk of bleeding if used with anticoagulant or antiplatelet drugs.
In human research, taking EPA has been shown to inhibit platelet aggregation.
Severity Moderate Likelihood Possible Evidence B

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 keep in mind with this pairing. Abciximab (ReoPro) is a potent IV antiplatelet drug given in the hospital, usually during procedures like a coronary stent placement. Its whole job is to stop platelets from clumping together. EPA, the omega-3 found in fish oil, has been shown in human studies to also gently reduce platelet stickiness. So you have two things nudging clotting in the same direction.

Stacking them could add up to a higher bleeding risk, meaning easier bruising, bleeding at the IV or catheter site, or harder-to-stop bleeds. The good news is that abciximab is given by your care team in a monitored setting, so they're already watching for this. Be sure to tell your doctor or pharmacist about any fish oil or EPA supplements you take so they can factor it in.

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.”
