Evodia and Eslicarbazepine Acetate

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

Moderate

CYTOCHROME P450 3A4 (CYP3A4) INDUCERS

Why this applies to Eslicarbazepine Acetate

Eslicarbazepine Acetate falls under CYTOCHROME P450 3A4 (CYP3A4) INDUCERS — the group Evodia interacts with.

Theoretically, taking CYP3A4 inducers might decrease the levels and clinical effects of evodia.
Animal research shows that concomitant administration of dexamethasone, a known CYP3A4 inducer, with the alkaloid constituents of evodia significantly reduces the area under the curve (AUC), maximum concentration (Cmax), and half-life of these constituents.
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 key thing to understand about this pairing: the interaction works on the Evodia, not on your seizure medicine. Eslicarbazepine (Aptiom) is a mild inducer of the CYP3A4 enzyme, which means it can speed up how your body breaks down certain other substances. The lab and animal research suggests that an enzyme speed-up like this could lower the levels of Evodia's active compounds, so the herb may simply do less of whatever you were hoping it would do.

The good news is that your Aptiom levels and seizure control aren't expected to drop because of Evodia here. Still, this is based only on test-tube and animal studies, so it's theoretical. Since Evodia hasn't been well studied in people and your seizure care is too important to gamble with, please run it by your pharmacist or neurologist before adding it.

From our pharmacist’s overview on the Eslicarbazepine Acetate page

“Missing even part of a dose of Aptiom (eslicarbazepine acetate) can mean a breakthrough seizure, which is why I read this list with real care. Of the 37 supplement ingredients on file, only activated charcoal rates major; it binds the medicine in your gut and can sharply cut what reaches your blood.”
