Interaction report

Coleus and Apixaban

These two interact in 2 distinct ways. Each one is explained separately below.

Why Are There 2 Interactions?

Coleus interacts with whole categories of medication. Apixaban falls into 2 of those categories, so it can interact with Coleus in 2 different ways. We’ve listed each one below — your overall risk is driven by the most serious of them (Moderate).

Moderate

CYTOCHROME P450 3A4 (CYP3A4) SUBSTRATES

1 of 2

Why this applies to Apixaban

Apixaban falls under CYTOCHROME P450 3A4 (CYP3A4) SUBSTRATES — the group Coleus interacts with.

Theoretically, taking coleus might decrease serum levels of drugs metabolized by CYP3A4.
In vitro research shows that coleus can activate the nuclear receptor, pregnane X receptor (PXR), which results in increased expression of CYP3A4. Although the clinical significance of this is not known, use caution when considering concomitant use of coleus and other drugs affected by these enzymes.
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 gist for Eliquis (apixaban): your body partly clears it using a liver enzyme called CYP3A4. Lab studies hint that Coleus (forskolin) may rev up that enzyme, which could in theory make you break down apixaban faster and leave less of it in your blood. Since apixaban's whole job is to prevent clots, lower levels could mean it doesn't protect you as well, raising the worry of a stroke or a clot in the leg or lung.

I want to be honest about the strength here. This is only test-tube evidence, not real patient data, so we truly don't know if it matters in people. Still, because apixaban is a blood thinner where consistency counts, please check with your pharmacist or doctor before pairing it with Coleus.

ANTICOAGULANT/ANTIPLATELET DRUGS

2 of 2

Apixaban also falls under ANTICOAGULANT/ANTIPLATELET DRUGS.

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 short version on combining Coleus with Eliquis (apixaban). Apixaban is already a blood thinner that blocks a clotting factor, so it lowers your body's ability to form clots. The concern with Coleus is that its active compound, forskolin, may make platelets (the cells that help your blood stick together and plug a leak) a little less sticky. Stack that on top of apixaban and, in theory, you could bruise or bleed a bit more easily.

I want to be honest about the strength of this, though: it comes only from lab and animal studies, not real-world cases in people. So it's a theoretical caution, not a proven danger. Still, since apixaban already carries a real bleeding risk, please run any Coleus product by your pharmacist or doctor first, and watch for unusual bruising, nosebleeds, or bleeding that won't stop.

What These Ratings Mean

Every interaction above is graded three ways — here’s the key to each label.

Severity how clinically significant the interaction is
Major

Clinically significant. Avoid the combination, or use only under close professional supervision.

Moderate

Usually worth avoiding or managing — may need monitoring, a dose change, or timing apart.

Minor

Generally not serious. Be aware of it and mention it to your pharmacist.

Likelihood how strong the evidence is that the interaction actually happens in people
  • LikelyWell-controlled human studies have demonstrated the likely existence of this interaction.
  • ProbableInteraction has not been documented in well-controlled studies, however, the interaction has been demonstrated in some small human studies or in controlled animal studies in conjunction with multiple case reports.
  • PossibleInteraction 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.
  • UnlikelyInteraction has been demonstrated in animal or in lab research but has been shown not to occur in humans.
Evidence the quality of the studies behind the rating (graded A–D)
  • AHigh-quality meta-analysis (quantitative systematic review).
  • BCase-control study.
  • CConsensus.
  • DAnecdotal evidence.

These ratings are for information only. Never start, stop, or otherwise change your therapy before speaking with your provider.

From our pharmacist’s overview on the Apixaban page

“St. John's wort can weaken apixaban (Eliquis), speeding how the body clears this blood thinner and leaving you less protected from the strokes and clots it is prescribed to prevent.”

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.

About Apixaban

What Is Apixaban Used For?

Brand name: Eliquis

Apixaban is used to reduce the risk of stroke and dangerous clots traveling through the body in adults with nonvalvular atrial fibrillation (an irregular heart rhythm not caused by a heart valve problem). It is also used to prevent deep vein thrombosis (DVT — a blood clot in the leg) in adults after hip or knee replacement surgery, and to treat DVT and pulmonary embolism (PE — a blood clot in the lungs) in adults, including reducing the risk of those clots coming back.

Eliquis (the brand-name tablet and kit) is additionally approved to treat venous thromboembolism (VTE — blood clots in the veins) and reduce the risk of recurrent VTE in pediatric patients from birth and older, after at least 5 days of initial anticoagulant treatment. The generic apixaban tablet carries the adult indications only.
