Jequirity and Sirolimus (albumin bound)

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

Minor

CYTOCHROME P450 3A4 (CYP3A4) SUBSTRATES

Why this applies to Sirolimus (albumin bound)

Sirolimus (albumin bound) falls under CYTOCHROME P450 3A4 (CYP3A4) SUBSTRATES — the group Jequirity interacts with.

In vitro research shows that jequirity extract inhibits CYP3A4 enzymes. Theoretically, taking jequirity may inhibit the metabolism of CYP3A4 substrates.
Severity Minor Likelihood Unlikely Evidence D

Interaction has been demonstrated in animal or in lab research but has been shown not to occur in humans..

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

First things first: jequirity itself is genuinely poisonous and should never be taken, so please don't use it at all. Setting that aside, here's what the interaction note means for your sirolimus (Fyarro). Your liver uses an enzyme called CYP3A4 to break sirolimus down. Lab studies suggest jequirity can slow that enzyme, which in theory could let sirolimus build up to higher levels in your blood.

For an active drug like sirolimus, more in your system can mean more side effects, such as mouth sores, low blood counts, infections, swelling, or high blood sugar and cholesterol. That said, this is only test-tube evidence and rated unlikely. The real concern is the toxin, not the interaction. Please bring any supplement up with your oncology team or pharmacist.
