Jequirity and Ponesimod

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

Minor

CYTOCHROME P450 3A4 (CYP3A4) SUBSTRATES

Why this applies to Ponesimod

Ponesimod 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 isn't really a supplement you should be taking at all. Its seeds contain abrin, a toxin in the same family as ricin, and swallowing even a chewed seed can be deadly. So my honest advice is to steer clear of it entirely, regardless of your MS medication.

On the interaction itself, the concern is theoretical and comes only from lab (test tube) work, not from people. In those studies, jequirity extract slowed down a liver enzyme called CYP3A4, which is one of the main pathways your body uses to clear Ponesimod. If that slowdown happened in real life, Ponesimod could build up a bit, possibly meaning more side effects like a slow heart rate, headache, or raised liver enzymes. The evidence here is weak, but the bigger issue is jequirity's toxicity. Please talk with your pharmacist or doctor before adding anything new.

Jequirity (Abrus precatorius) is a tropical plant whose bright red, black-tipped seeds contain abrin, one of the most toxic plant proteins known.
