Reishi Mushroom 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 Reishi Mushroom interacts with.

Theoretically, high doses of reishi mushroom might increase the risk of bleeding.
A dose of 1.5 grams daily of reishi mushroom does not seem to decrease platelet aggregation, but a higher dose of 3 grams daily does.
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 reishi and bromfenac (Prolensa, Bromsite). Bromfenac is an eye drop you use after cataract surgery, and it's an NSAID, which is a class that can gently affect bleeding. The concern on file is that high doses of reishi (around 3 grams a day, not 1.5 grams) might slightly increase bleeding risk on their own.

I want to be honest though: this is theoretical, based only on lab and animal studies, and bromfenac is applied right to the eye, so very little gets into your bloodstream. That makes a real bleeding problem unlikely from the combo. Still, since you're healing from eye surgery, mention any reishi supplement to your eye surgeon or pharmacist so they can keep an eye on things.

About Reishi Mushroom

What is Reishi Mushroom?

Reishi Mushroom
  • Immune support
  • Fatigue and general well-being
  • Stress and sleep
  • Inflammation
  • Heart and cholesterol health

Reishi is a traditional Asian mushroom widely used to support the immune system and overall wellness. Human evidence for most of its claimed benefits is limited or low-quality, so it should not replace proven treatments. It is generally well tolerated for short-term use, but check with your pharmacist or doctor before starting, especially if you are pregnant, nursing, or take other medicines.
