Reishi Mushroom and Ticlopidine

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

Moderate

ANTICOAGULANT/ANTIPLATELET DRUGS

Why this applies to Ticlopidine

Ticlopidine 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, PharmD, BCPS
Dr. Brian Staiger explains PharmD, Clinical Pharmacist

Here's the gist: Ticlopidine already works by keeping your platelets from clumping together to form clots. Reishi mushroom, at higher concentrated doses, may do a little of the same thing. So when you stack the two, you could be nudging your bleeding risk a bit higher than the Ticlopidine alone.

I want to be honest about how strong this concern is. The evidence is mostly lab and animal based, so it's more of a theoretical caution than a proven problem. Interestingly, lower reishi doses (around 1.5 grams a day) didn't seem to affect platelets, while higher doses (about 3 grams daily) might. Watch for easy bruising, nosebleeds, bleeding gums, or cuts that take longer to stop, and please check with your pharmacist or doctor before adding reishi.

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.

About Ticlopidine

What Is Ticlopidine Used For?

Brand names: Ticlid, Ticlopidine

  • Ticlopidine is used to reduce the risk of stroke in people who have had a stroke or have had warning signs of a stroke and who cannot be treated with aspirin. Ticlopidine is also used along with aspirin to prevent blood clots from forming in coronary stents (metal tubes surgically placed in clogged blood vessels to improve blood flow). It works by preventing platelets (a type of blood cell) from collecting and forming clots.
