Wasabi 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 Wasabi interacts with.

Theoretically, wasabi might increase the risk of bleeding with anticoagulant or antiplatelet drugs.
In vitro research shows that 6-(methylsulfinyl) hexyl isothiocyanate, a constituent of wasabi, inhibits 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 explains PharmD, Clinical Pharmacist

Ticlopidine already does one main job: it keeps your platelets from clumping together so clots don't form. Here's the thing about wasabi. Lab studies suggest one of its compounds can also make platelets less sticky. So if you stacked a concentrated wasabi supplement on top of ticlopidine, you'd theoretically be nudging that same anti-clotting effect a little further, which could raise your bleeding risk.

In real terms, that might mean easier bruising, nosebleeds, bleeding gums, or cuts that are slow to stop. I'll be honest though, this concern comes from test-tube work, not people, and the small amount of wasabi on your sushi is very unlikely to matter. A daily wasabi capsule is a different story, so check with your pharmacist or doctor before starting one.

From our pharmacist’s overview on the Ticlopidine page

“Ticlopidine (Ticlid) keeps platelets from clumping to prevent clots, so it already raises bleeding risk on its own, and over 200 of the 221 supplements flagged for it push in that same direction. That stacking effect deserves genuine respect from anyone taking this drug.”

About Wasabi

What is Wasabi?

Wasabi
  • Flavoring for sushi and other foods
  • Antimicrobial support
  • Anti-inflammatory support
  • Antioxidant support
  • General immune support

Wasabi is best known as the pungent green condiment served with sushi, made from a Japanese plant in the cabbage family. Its natural compounds (isothiocyanates) show antimicrobial and antioxidant activity in lab studies, but there is very little human research to support taking it as a supplement. As a food it is generally safe; as a concentrated supplement, talk with your pharmacist or doctor first.

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.
