Yohimbe and Moclobemide

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

Why Are There 2 Interactions?

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

Major

MONOAMINE OXIDASE INHIBITORS (MAOIs)

1 of 2

Why this applies to Moclobemide

Moclobemide falls under MONOAMINE OXIDASE INHIBITORS (MAOIs) — the group Yohimbe interacts with.

Concomitant use of MAOIs with yohimbe can result in additive effects.
Yohimbine, a constituent of yohimbe, has MAO inhibitory effects. At high doses, yohimbine is a non-selective inhibitor of MAO.
Severity Major Likelihood Likely Evidence D

Well-controlled human studies have demonstrated the likely existence of this interaction.

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

Here's the concern with pairing these two. Moclobemide is itself a reversible MAO inhibitor, used as an antidepressant. Yohimbine, the active piece of yohimbe, can also block MAO at higher doses, and on top of that it revs up your sympathetic nervous system. Stacking two things that push in the same direction is the issue here.

Together they could send your blood pressure climbing and your heart racing, which may show up as headache, pounding heartbeat, sweating, anxiety, or a dangerous spike in pressure. This is rated a major, likely interaction, though the evidence is largely theoretical based on how these drugs work. Still, with MAOIs I take blood pressure warnings seriously. Please check with your doctor or pharmacist before combining them.

Moderate

CYTOCHROME P450 2D6 (CYP2D6) INHIBITORS

2 of 2

Moclobemide also falls under CYTOCHROME P450 2D6 (CYP2D6) INHIBITORS.

CYP2D6 inhibitors may increase the levels and adverse effects of yohimbine, a constituent of yohimbe.
In vitro and clinical research shows that the yohimbe bark constituent, yohimbine, is metabolized by CYP2D6 isoenzymes. Paroxetine, a cytochrome P450 (CYP) 2D6 inhibitor, increases the maximum serum concentration of yohimbine and reduces the clearance of yohimbine compared to yohimbine alone in patients who are extensive CYP2D6 metabolizers..
Severity Moderate Likelihood Probable Evidence B

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 thing to watch with this pair. Your body uses an enzyme called CYP2D6 to clear yohimbine, the active part of yohimbe. Moclobemide blocks that enzyme, so yohimbine can't be broken down as quickly and tends to build up in your system. That means a normal yohimbe dose may hit you harder than expected, with effects like spikes in blood pressure, a racing or pounding heart, anxiety, sweating, and trouble sleeping.

There's an extra wrinkle: moclobemide is also an MAOI, and combining it with a stimulant like yohimbine adds its own risk of dangerously high blood pressure. The evidence here is decent (a clinical study with a similar enzyme blocker showed higher yohimbine levels). Please check with your pharmacist or doctor before mixing these.

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.

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.
