Iboga and Prucalopride

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

Moderate

SEROTONERGIC DRUGS

Why this applies to Prucalopride

Prucalopride falls under SEROTONERGIC DRUGS — the group Iboga interacts with.

Theoretically, taking iboga with serotonergic drugs might increase levels of serotonin, resulting in additive effects with serotonergic drugs.
Ibogaine, a constituent in iboga, has serotonergic effects. Theoretically, combining serotonergic drugs with iboga might increase the risk of serotonergic side effects, including serotonin syndrome and cerebral vasoconstrictive disorders. Monitor patients for signs of serotonin syndrome and other serotonergic side effects if using iboga with serotonergic drugs.
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 short version: Prucalopride (Motegrity, Resolor, Resotran) works on serotonin receptors in your gut to get the bowel moving. Iboga, through its compound ibogaine, also nudges serotonin activity in the body. On paper, stacking two things that both touch serotonin could add up and, in rare cases, raise the risk of too much serotonin (called serotonin syndrome). Warning signs include agitation, a racing heart, shivering, sweating, muscle twitching, or feeling dizzy.

I want to be honest with you: this concern is theoretical, based on how these substances behave, not on real reports with prucalopride. Honestly, my bigger worry is iboga itself, since it can cause dangerous heart rhythm problems and is illegal in the U.S. Please talk with your pharmacist or doctor before mixing anything with prucalopride.

Iboga is a Central African shrub whose root bark contains ibogaine, a powerful hallucinogenic compound studied mainly for addiction.

About Prucalopride

What Is Prucalopride Used For?

Brand names: Resotran, Resolor, Motegrity

Prucalopride tablets — sold under the brand name Motegrity and also available as generic prucalopride and prucalopride succinate — are indicated for the treatment of chronic idiopathic constipation (CIC) in adults. CIC is ongoing constipation with no identified underlying cause.

This indication applies to all approved oral tablet forms of prucalopride. It is not approved for use in children; a study in pediatric patients was stopped early because the medication did not show effectiveness in that age group.
