Oregon Grape and Bromfenac Sodium

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

Moderate

ANTICOAGULANT/ANTIPLATELET DRUGS

Why this applies to Bromfenac Sodium

Bromfenac Sodium falls under ANTICOAGULANT/ANTIPLATELET DRUGS — the group Oregon Grape interacts with.

Theoretically, Oregon grape might increase the risk of bleeding when taken with anticoagulant or antiplatelet drugs.
In vitro and in vivo research suggests that berberine, a constituent of Oregon grape, can 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, PharmD, BCPS
Dr. Brian Staiger explains PharmD, Clinical Pharmacist

Here's the gist with this pairing. Bromfenac is an NSAID, and like other drugs in that family it can nudge up bleeding risk by interfering with platelets. Oregon grape contains berberine, which in lab and animal studies appears to make platelets less sticky too. Stack those two together and the worry is a slightly higher chance of bleeding or bruising.

That said, your bromfenac is an eye drop used after cataract surgery, so very little gets into your bloodstream. The bleeding concern here is mostly theoretical and based on test-tube and animal data, not strong human studies. Still, around eye surgery it's smart to play it safe, so let your eye surgeon or pharmacist know you're using Oregon grape before you start.
