Rauwolscine and Enasidenib

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

Moderate

CYTOCHROME P450 2D6 (CYP2D6) SUBSTRATES

Why this applies to Enasidenib

Enasidenib falls under CYTOCHROME P450 2D6 (CYP2D6) SUBSTRATES — the group Rauwolscine interacts with.

Theoretically, rauwolscine might increase levels of drugs metabolized by CYP2D6.
Rauwolscine is structurally related to yohimbine. In vitro research shows that yohimbine inhibits CYP2D6 enzyme activity.
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 situation if you're thinking about pairing a rauwolscine supplement with your Idhifa (enasidenib). Rauwolscine is a cousin of yohimbine, and in lab studies yohimbine slows down an enzyme called CYP2D6, which is one of the pathways your body uses to clear certain drugs. The thinking is that blocking it could let those drugs build up a bit higher than usual.

I want to be honest with you though: this is a theoretical concern based only on test-tube data, not real-world cases. Enasidenib already carries its own serious risks, like a dangerous immune reaction called differentiation syndrome, nausea, and elevated bilirubin. Since this is a cancer medicine where dosing really matters, please don't add a stimulant fat-burner without first checking with your oncologist or pharmacist.

About Rauwolscine

What is Rauwolscine?

  • Fat loss and weight management
  • Bodybuilding and physique support
  • Energy and stimulant effects
  • Athletic performance
  • Libido support

Rauwolscine (alpha-yohimbine) is a stimulant alkaloid closely related to yohimbine that is marketed mainly in fat-burning and pre-workout supplements. Human evidence for its benefits is very limited, and it can raise heart rate and blood pressure and cause anxiety, so it should be used with caution and is not recommended for people with heart conditions, anxiety, or during pregnancy or breastfeeding.

About Enasidenib

What Is Enasidenib Used For?

Brand name: Idhifa

Idhifa (enasidenib) is used to treat adult patients with acute myeloid leukemia (AML) — a fast-moving cancer of the blood and bone marrow — whose disease has come back after treatment (relapsed) or has stopped responding to treatment (refractory). It is specifically for patients whose leukemia has a mutation in the IDH2 gene, which must be confirmed by an FDA-approved test before starting therapy.
