Cilantro and Treprostinil (IV)

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

Moderate

ANTICOAGULANT/ANTIPLATELET DRUGS

Why this applies to Treprostinil (IV)

Treprostinil (IV) 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 explains PharmD, Clinical Pharmacist

Here's the thing to know about treprostinil (Remodulin). Besides keeping the blood vessels in your lungs relaxed, this medication also makes your platelets a little less sticky, so it can slightly raise bleeding risk on its own. The concern with cilantro is that lab studies hint it may do something similar, gently slowing how platelets clump together. Stacked together, the theory is you could bruise more easily or bleed a bit more readily, for example nosebleeds or bleeding gums.

I want to be honest that this is a theoretical worry based on test-tube research, not real patient cases, and normal food amounts of cilantro in your cooking are very unlikely to matter. Concentrated cilantro supplements or essential oil are a different story. Before adding those, just run it by your pharmacist or doctor.

From our pharmacist’s overview on the Treprostinil (IV) page

“Bleeding risk is the thread running through nearly every supplement flagged for treprostinil (Remodulin), the IV therapy for pulmonary arterial hypertension. The drug itself discourages platelets from clumping, so the overwhelming majority of these ingredients could push that tendency further, and I would not add anything from this pag…”

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 Treprostinil Injection

What Is Treprostinil Injection Used For?

Brand name: Remodulin

Treprostinil injection is used to treat pulmonary arterial hypertension (PAH, WHO Group 1) — high blood pressure in the arteries that supply the lungs. It works to reduce the symptoms that make exercise difficult. Clinical studies included patients with moderate-to-severe PAH symptoms (NYHA Class II–IV) due to idiopathic or heritable PAH, PAH related to congenital heart defects, and PAH related to connective tissue diseases.

It is also used for PAH patients who need to transition off epoprostenol — a related medication — to slow the worsening of their condition during that switch. The risks and benefits of the transition should be carefully discussed with a specialist before starting.
