Coleus and Bivalirudin

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

Moderate

ANTICOAGULANT/ANTIPLATELET DRUGS

Why this applies to Bivalirudin

Bivalirudin falls under ANTICOAGULANT/ANTIPLATELET DRUGS — the group Coleus interacts with.

Theoretically, concomitant use of coleus and anticoagulant or antiplatelet drugs might increase the risk of bruising and bleeding.
In vitro and animal research shows that forskolin, a constituent of coleus, can inhibit platelet aggregation and adhesion.
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 thing to keep in mind: bivalirudin is a powerful blood thinner given through an IV, usually in the hospital during heart procedures like angioplasty. Its whole job is to slow down clotting so blood flows freely. Coleus (through its compound forskolin) may make platelets less sticky in lab studies, so in theory, stacking it on top of bivalirudin could nudge your bleeding risk a little higher.

I want to be honest about the evidence, though. This concern comes only from test tube and animal research, not real patients, so it's theoretical. On top of that, bivalirudin is given by professionals who monitor you closely. Still, if you take Coleus supplements, please mention it to your care team before any procedure so they have the full picture.

From our pharmacist’s overview on the Bivalirudin page

“Bivalirudin (Angiomax) is a strong intravenous blood thinner used during heart procedures like angioplasty, and because bleeding is already its main built-in danger, this list deserves genuine care. All 202 supplements on it interact the same basic way: they thin the blood or blunt platelets themselves, stacking bleeding risk on top of…”

About Coleus

What is Coleus?

Coleus
  • Weight management
  • Asthma and breathing
  • High blood pressure
  • Heart conditions
  • Glaucoma (eye pressure)
  • Exercise and body composition

Coleus is a plant from the mint family whose root contains a compound called forskolin, often marketed for weight loss, asthma, and heart health. While early lab and small human studies are interesting, solid proof that Coleus supplements help any of these conditions is limited. Talk to your pharmacist or doctor before using it, especially if you have heart problems or low blood pressure.
