Iboga and Pasireotide Diaspartate

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

Moderate

QT INTERVAL-PROLONGING DRUGS

Why this applies to Pasireotide Diaspartate

Pasireotide Diaspartate falls under QT INTERVAL-PROLONGING DRUGS — the group Iboga interacts with.

Theoretically, iboga may have an additive effect with drugs that prolong the QT interval.
Numerous case reports suggest that ibogaine, a constituent in iboga, can cause QT interval prolongation.
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 concern with combining these two. Pasireotide (Signifor) can stretch out a part of your heartbeat called the QT interval. Iboga, through its main compound ibogaine, has been linked in several case reports to the same kind of QT prolongation. When two things push in the same direction, the effect can add up, and a longer QT interval raises the risk of a dangerous, irregular heart rhythm.

This isn't about one drug changing the levels of the other. It's about both stressing your heart's electrical timing at once. The evidence for iboga here is anecdotal, but ibogaine already carries real reports of serious heart problems and deaths, so I'd take this seriously. Please don't make any changes on your own. Talk with your doctor or pharmacist first.

From our pharmacist’s overview on the Pasireotide Diaspartate page

“All 13 supplements on this page raise the same concern with pasireotide (Signifor), a drug for Cushing's disease that can itself lengthen the QT interval, the electrical reset time between heartbeats. Stack another QT-prolonging ingredient on top and the risk of a dangerous heart rhythm goes up, so treat these combinations with real care.”
