Yohimbe and Acitretin

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

Moderate

CYTOCHROME P450 3A4 (CYP3A4) INHIBITORS

Why this applies to Acitretin

Acitretin falls under CYTOCHROME P450 3A4 (CYP3A4) INHIBITORS — the group Yohimbe interacts with.

Theoretically, CYP3A4 inhibitors might increase the levels and adverse effects of yohimbine, a constituent of yohimbe bark.
In vitro and clinical research shows that the yohimbe bark constituent, yohimbine, is metabolized by CYP3A4 enzymes. Theoretically, drugs that inhibit CYP3A4 might increase the levels and adverse effects of yohimbine.
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 key thing to understand: in this pairing, acitretin isn't the drug that builds up, yohimbe is. Acitretin can act as a mild CYP3A4 inhibitor, and yohimbine (the active part of yohimbe) is broken down by that same CYP3A4 enzyme. So when you take them together, your body may clear the yohimbine more slowly, letting it climb higher than expected.

That matters because yohimbe on its own can already raise blood pressure, speed up your heart, and trigger jitteriness or anxiety. More yohimbine in your system could make those effects stronger. Honestly, this is theoretical and based on how the drugs work, not solid human studies. Still, given yohimbe's safety record, please check with your pharmacist or doctor before combining them.

From our pharmacist’s overview on the Acitretin page

“A course of Acitretin (Soriatane) for severe psoriasis runs for months, long enough for a multivitamin or detox product to slip in unexamined, and with this drug that carelessness carries real risk. Two of the 53 interacting ingredients are rated major.”

About Yohimbe

What is Yohimbe?

Yohimbe
  • Erectile dysfunction
  • Low sex drive
  • Sexual performance
  • Weight loss
  • Athletic performance

Yohimbe is a West African tree bark that contains yohimbine, a compound mainly promoted for erectile dysfunction and as an aphrodisiac. A prescription form of yohimbine has some evidence for erectile dysfunction, but over-the-counter yohimbe supplements vary widely in content and can cause serious side effects like high blood pressure and fast heart rate. Because of these safety concerns, talk to your pharmacist or doctor before using it.

About Acitretin

What Is Acitretin Used For?

Brand name: Soriatane

Acitretin capsules are approved to treat severe psoriasis in adults. It is typically reserved for patients whose psoriasis has not responded to other treatments, or when other treatments are not appropriate options.

Because of serious risks — including the risk of severe birth defects — acitretin is not a first-line choice. In women who could become pregnant, it should only be used when the benefits clearly outweigh the risks and strict pregnancy-prevention measures are in place.
