Yohimbe and Ropivacaine

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

Minor

CYTOCHROME P450 1A2 (CYP1A2) SUBSTRATES

Why this applies to Ropivacaine

Ropivacaine falls under CYTOCHROME P450 1A2 (CYP1A2) SUBSTRATES — the group Yohimbe interacts with.

Theoretically, yohimbe might decrease the levels and clinical effects of CYP1A2 substrates.
In vitro research shows that yohimbe extract induces CYP1A2 enzymes.
Severity Minor 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 situation with these two. Ropivacaine (Naropin) is a local anesthetic, usually given as an injection during surgery, labor, or for nerve blocks. Your liver clears it partly through an enzyme called CYP1A2. Lab studies hint that yohimbe might speed up that enzyme, which in theory could clear ropivacaine a little faster and slightly shorten how long the numbing lasts.

I want to be straight with you though: this is only test-tube evidence, it's rated minor, and ropivacaine is given by a healthcare professional who watches how you respond and adjusts the dose. It is not a prodrug, so yohimbe wouldn't make it stronger. The bigger real-world worry with yohimbe is its effect on blood pressure and heart rate around any procedure, so always mention it to your anesthesia team or pharmacist beforehand.

This page covers Yohimbe only. If you take other supplements — a multivitamin, a sleep aid, something for joints — the Ropivacaine page lists 85 supplements it has a documented interaction with, worst first, each one explained.

The most serious there right now: Fever Bark (major), Adrafinil (moderate), African Wild Potato (moderate), Ashitaba (moderate) and Bacopa (moderate).

By severity: 1 major · 59 moderate · 25 minor.

From our pharmacist’s overview on the Ropivacaine page

“Fever bark stands apart on this page. It carries the only major rating among the 85 supplements and herbs on file for ropivacaine (Naropin), the numbing medicine used in epidurals and nerve blocks, because reserpine, one of its compounds, has been tied to unstable blood pressure and heart function during general anesthesia.”

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.
