Kratom and Brivaracetam

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

Minor

CYTOCHROME P450 2C19 (CYP2C19) SUBSTRATES

Why this applies to Brivaracetam

Brivaracetam falls under CYTOCHROME P450 2C19 (CYP2C19) SUBSTRATES — the group Kratom interacts with.

Theoretically, kratom might increase the levels of drugs metabolized by CYP2C19.
In vitro research shows that kratom extract weakly inhibits CYP2C19 enzyme activity.
Severity Minor 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 short version for Briviact (brivaracetam): one of the ways your body clears this seizure medicine is through a liver enzyme called CYP2C19. Lab studies (test-tube only) suggest kratom may weakly slow that enzyme down. If that happened in real life, brivaracetam could build up a little, which might mean more drowsiness, dizziness, tiredness, or trouble with balance and coordination.

I want to be honest that this is theoretical and the effect looks mild, so I wouldn't lose sleep over it. The bigger concern is that kratom acts on opioid receptors and can add its own sedation on top of your medicine. Please loop in your pharmacist or doctor before mixing the two, and never adjust your brivaracetam on your own.

This page covers Kratom only. If you take other supplements — a multivitamin, a sleep aid, something for joints — the Brivaracetam page lists 50 supplements it has a documented interaction with, worst first, each one explained.

The most serious there right now: Activated Charcoal (major), Adrafinil (moderate), Artichoke (moderate), Bacopa (moderate) and Baikal Skullcap (moderate).

By severity: 1 major · 36 moderate · 13 minor.

From our pharmacist’s overview on the Brivaracetam page

“Brivaracetam (Briviact) controls seizures, and anything that shifts its blood level risks that control, so I read this list with genuine vigilance. Only one of the 50 ingredients is rated major: activated charcoal, which can bind the drug in the gut and cut how much reaches the bloodstream, the wrong direction for seizure protection.”
