Rauvolfia Vomitoria and Safinamide Mesylate

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

Major

MONOAMINE OXIDASE INHIBITORS (MAOIs)

Why this applies to Safinamide Mesylate

Safinamide Mesylate falls under MONOAMINE OXIDASE INHIBITORS (MAOIs) — the group Rauvolfia Vomitoria interacts with.

Theoretically, concomitant use might cause additive effects.
Yohimbine, a constituent of Rauvolfia vomitoria, has MAO inhibitory effects. At high doses, yohimbine is a non-selective inhibitor of MAO.
Severity Major Likelihood Probable Evidence D

Interaction 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..

Dr. Brian Staiger, PharmD, BCPS
Dr. Brian Staiger explains PharmD, Clinical Pharmacist

Here's the concern with pairing Rauvolfia vomitoria and Xadago (safinamide). Safinamide is already an MAO-B inhibitor, and rauvolfia contains compounds (like yohimbine) that can also block MAO enzymes, especially at higher doses. So you'd essentially be stacking two things that work on the same pathway. On top of that, rauvolfia strongly affects blood pressure and the brain's chemical messengers, which makes the combination riskier.

In real life, that overlap could push your blood pressure up or down unpredictably, and in theory raise the chance of a dangerous spike or serotonin-related symptoms (agitation, sweating, racing heart, confusion). This is rated as a theoretical interaction based on pharmacology, not confirmed cases, but because it's potentially serious I'd treat it cautiously. Please don't combine these without checking with your doctor or pharmacist first.

About Rauvolfia Vomitoria

What is Rauvolfia Vomitoria?

  • High blood pressure
  • Anxiety and agitation
  • Sleep problems
  • Mental health symptoms (traditional use)
  • Fever and general ailments

Rauvolfia vomitoria is an African shrub whose root contains powerful alkaloids, including reserpine, that have historically been used for high blood pressure and agitation. Because these compounds can strongly affect blood pressure, mood, and the nervous system, the plant can cause serious side effects and is not a casual supplement. Always talk to a doctor or pharmacist before using it.
