Allspice and Vorapaxar

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

Moderate

ANTICOAGULANT/ANTIPLATELET DRUGS

Why this applies to Vorapaxar

Vorapaxar falls under ANTICOAGULANT/ANTIPLATELET DRUGS — the group Allspice interacts with.

Theoretically, combining allspice with an antiplatelet or anticoagulant drug might increase the risk of bleeding.
Eugenol, a constituent of allspice, is reported to have antiplatelet activity. However, this interaction has yet not been reported in humans.
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 simple version: Vorapaxar (Zontivity) already lowers your blood's ability to clot by keeping platelets from sticking together. Allspice contains eugenol, a compound that lab studies suggest may also have a mild platelet-blocking effect. Stack the two and, in theory, you could nudge your bleeding risk a little higher, which might show up as easier bruising, nosebleeds, bleeding gums, or cuts that take longer to stop.

I want to be honest about the evidence though: this is a theoretical concern based on how eugenol behaves in the lab, not something actually reported in people. The sprinkle of allspice you use in cooking is very unlikely to matter. Concentrated extracts or allspice essential oil are a different story, so check with your pharmacist or doctor before using those.

From our pharmacist’s overview on the Vorapaxar page

“Vorapaxar (Zontivity) keeps platelets from clumping after a heart attack or clogged leg arteries, so it raises bleeding risk by design, and adding supplements calls for real caution. Of the 282 ingredients on file, 202 can thin the blood further, stacking their antiplatelet effects on the drug's.”

About Allspice

What is Allspice?

Allspice
  • Digestive upset and gas
  • Muscle and joint pain (topical)
  • Toothache and oral discomfort
  • Antimicrobial uses
  • Flavoring in food and drinks

Allspice is a popular cooking spice from a Caribbean evergreen tree that has long been used in folk medicine for digestion, pain, and infections. There is very little high-quality human research to support these medicinal uses, so it is best thought of as a flavorful food rather than a proven treatment. Amounts used in cooking are generally considered safe, but concentrated extracts and the essential oil should be used carefully.

About Vorapaxar

What Is Vorapaxar Used For?

Brand name: Zontivity

Zontivity (vorapaxar) is used to lower the risk of heart attack, stroke, cardiovascular death, and the need for urgent procedures to open blocked arteries. It is prescribed for people who have already had a heart attack or who have peripheral arterial disease (PAD) — a condition where arteries outside the heart become narrowed or blocked.

Zontivity is not used alone. It is given alongside aspirin and/or clopidogrel as part of a broader antiplatelet treatment plan.
