Cilantro 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 Cilantro interacts with.

In vitro research suggests that extracts of cilantro can inhibit platelet aggregation. Theoretically, cilantro might increase the risk of bleeding when used concomitantly with anticoagulant/antiplatelet drugs. Some of these drugs include aspirin, clopidogrel (Plavix), nonsteroidal anti-inflammatory drugs (NSAIDs) such as diclofenac (Voltaren, Cataflam, others), ibuprofen (Advil, Motrin, others), naproxen (Anaprox, Naprosyn, others), dalteparin (Fragmin), enoxaparin (Lovenox), heparin, warfarin (Coumadin), and others.
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: Vorapaxar (Zontivity) is already a blood thinner that keeps your platelets from clumping together. Lab studies hint that cilantro extracts can lightly do the same thing. Stack the two, and in theory you could nudge your bleeding risk a bit higher. Think easier bruising, nosebleeds, bleeding gums, or cuts that take longer to stop. Remember, Vorapaxar is often taken alongside aspirin and Plavix, so you're already getting a strong antiplatelet effect.

The good news is this concern is theoretical and comes from test-tube work, not real patients. Eating cilantro as a garnish in your food is very unlikely to matter. Concentrated cilantro supplements or 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 Cilantro

What is Cilantro?

  • Digestive upset and bloating
  • Antimicrobial support
  • Antioxidant support
  • Heavy metal 'detox' (chelation) claims
  • Culinary flavoring

Cilantro is the leafy part of the Coriandrum sativum plant and is widely eaten as a food, where it is considered safe for most people. While it has antioxidant and antimicrobial properties in lab studies, strong human evidence for any specific health benefit is lacking, and popular 'detox' claims are not well supported. Talk with your pharmacist or doctor before using concentrated cilantro supplements or essential oil.

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.
