Alpine Ragwort and Rufinamide

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

Moderate

CYTOCHROME P450 3A4 (CYP3A4) INDUCERS

Why this applies to Rufinamide

Rufinamide falls under CYTOCHROME P450 3A4 (CYP3A4) INDUCERS — the group Alpine Ragwort interacts with.

Theoretically, CYP3A4 inducers might increase the risk of adverse effects from the pyrrolizidine alkaloid (PA) constituents in alpine ragwort.
Alpine ragwort contains PAs. PAs are substrates of CYP3A4. Theoretically, drugs that induce CYP3A4 might increase the conversion of PAs to toxic metabolites.
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 explains PharmD, Clinical Pharmacist

First things first: I really wouldn't take Alpine Ragwort at all. It contains pyrrolizidine alkaloids, plant compounds your liver can turn into toxic byproducts that injure liver cells. There's no proven benefit to balance that risk.

Here's how Rufinamide (Banzel) fits in. Rufinamide can mildly speed up a liver enzyme called CYP3A4, the same enzyme that converts these alkaloids into their harmful forms. So in theory, combining them could mean your liver makes more of those toxic byproducts, raising the chance of liver damage. I want to be honest that this is a theoretical concern based on lab work, not real patient reports. Still, since the downside is liver injury and there's no upside to the supplement, please skip the ragwort and run any herbal products past your pharmacist or doctor first.
