Yohimbe and Dexamfetamine

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

Moderate

STIMULANT DRUGS

Why this applies to Dexamfetamine

Dexamfetamine falls under STIMULANT DRUGS — the group Yohimbe interacts with.

Theoretically, taking yohimbe with stimulant drugs can have additive effects.
Yohimbine, a constituent of yohimbe, has sympathomimetic effects and increases blood pressure in a dose-dependent manner. Theoretically, taking yohimbe with stimulant drugs can have additive stimulant and hypertensive effects.
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 thing to know: dexamfetamine is already a stimulant. It revs up your nervous system, which can raise your heart rate and blood pressure and leave some folks feeling jittery, anxious, or unable to sleep. Yohimbe, through its active piece yohimbine, has its own stimulant-like push on the body and can bump up blood pressure too.

So when you stack the two, the worry is that those effects pile on top of each other. You might see a faster heartbeat, higher blood pressure, more restlessness, or palpitations. This is a theoretical concern based on how both work, not something proven in studies, and OTC yohimbe doses vary a lot. Still, I'd run it by your pharmacist or doctor before combining them.

From our pharmacist’s overview on the Dexamfetamine page

“Dexamfetamine is already a powerful stimulant, used for ADHD and narcolepsy, so most of the 84 supplements on this list matter because they push the same way. Forty-four are stimulants themselves, from everyday caffeine sources like coffee and tea up to ephedra, one of six major-rated entries and one I would not combine at all.”

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.
