Cannabis 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 Cannabis interacts with.

Theoretically, CYP3A4 inducers might reduce the levels and clinical effects of cannabis.
Delta-9-tetrahydrocannabinol (THC), an active constituent of cannabis, is a substrate of CYP3A4 enzymes.
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 the spotlight is actually on the cannabis, not your seizure medicine. Eslicarbazepine (Aptiom) can act as a mild CYP3A4 inducer, meaning it can speed up one of the liver pathways that breaks down THC, the main active part of cannabis. In theory, that could clear THC out a little faster, so you might feel less of an effect from the same amount.

I want to be honest that this one is theoretical, based on how these compounds behave rather than solid human studies, so the real-world impact may be small or hard to notice. It does not mean your Aptiom stops working. Since cannabis can also cause drowsiness and dizziness that may stack with this medicine, please loop in your doctor or pharmacist before combining them.

About Cannabis

What is Cannabis?

Cannabis
  • Chronic pain
  • Nausea and vomiting from chemotherapy
  • Muscle spasticity (e.g., multiple sclerosis)
  • Anxiety and stress
  • Sleep problems
  • Appetite stimulation

Cannabis contains many active compounds, mainly THC (which causes a 'high') and CBD (which does not). Some uses, such as chemotherapy-related nausea, certain seizure disorders, and muscle spasticity, have meaningful evidence, while many other popular uses are not well proven. It can cause real side effects and impairment, so talk to your doctor or pharmacist and follow your local laws before using it.
