Coleus and Lesinurad

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

Moderate

CYTOCHROME P450 2C9 (CYP2C9) SUBSTRATES

Why this applies to Lesinurad

Lesinurad falls under CYTOCHROME P450 2C9 (CYP2C9) SUBSTRATES — the group Coleus interacts with.

Theoretically, taking coleus may affect drugs metabolized by CYP2C9 and increase the risk of adverse effects or reduce the effectiveness.
Research on the effect of coleus on CYP2C9 is conflicting. Some animal research shows that coleus extract can induce CYP2C9, while in vitro research shows that coleus can inhibit CYP2C9. Until more is known, advise patients that taking coleus might increase or decrease levels of drugs metabolized by CYP2C9.
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: your gout medicine Lesinurad is processed by a liver enzyme called CYP2C9, and Coleus (forskolin) may tinker with that same enzyme. The catch is that the research pulls in two directions. Some animal studies suggest Coleus could speed up CYP2C9 (which might leave less Lesinurad working, so your uric acid control could slip), while lab dish studies suggest it could slow it down (which might raise Lesinurad levels and the chance of side effects like kidney strain or headache).

This is theoretical and based only on lab and animal data, so I wouldn't panic. Lesinurad already carries kidney cautions, so before adding a Coleus supplement, just run it past your pharmacist or doctor first.

See Every Supplement That Interacts With Lesinurad

This page covers Coleus only. If you take other supplements — a multivitamin, a sleep aid, something for joints — the Lesinurad page lists 97 supplements it has a documented interaction with, worst first, each one explained.

The most serious there right now: Activated Charcoal (major), Adrafinil (moderate), African Wild Potato (moderate), Alkanna (moderate) and Alpine Ragwort (moderate).

By severity: 1 major · 74 moderate · 22 minor.

From our pharmacist’s overview on the Lesinurad page

“Activated charcoal is the one major-rated entry among the 97 supplements and herbs on file for lesinurad (Zurampic), and it undermines the drug directly. Charcoal binds medicines in the gut and can cut how much lesinurad you absorb, letting uric acid climb and gout flare.”

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 Lesinurad

What Is Lesinurad Used For?

Brand name: Zurampic

  • Lesinurad is used in combination with a xanthine oxidase inhibitor to treat hyperuricemia (high levels of uric acid) in people with gout (sudden attacks of redness, swelling, pain, and heat in one or more joints) whose disease is not controlled with their current medication. Lesinurad is in a class of medications called selective uric acid reabsorption inhibitors. It works by helping the kidneys to remove uric acid from the body.
