Cannabidiol (cbd) and Omaveloxolone

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

Moderate

CYTOCHROME P450 3A4 (CYP3A4) INDUCERS

Why this applies to Omaveloxolone

Omaveloxolone falls under CYTOCHROME P450 3A4 (CYP3A4) INDUCERS — the group Cannabidiol (cbd) interacts with.

Theoretically, CYP3A4 inducers might decrease cannabidiol levels.
Cannabidiol is a substrate of CYP3A4 enzymes. Theoretically, drugs that induce CYP3A4 enzymes might reduce the levels and effects of cannabidiol.
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

Here's the thing to notice about this pairing: the effect runs toward the CBD, not the other way around. Omaveloxolone (Skyclarys) can act like a mild CYP3A4 inducer, meaning it can speed up the liver enzyme that breaks down CBD. On paper, that could lower how much CBD stays in your system, so you might feel less of whatever benefit you were hoping for from it.

I want to be honest that this is a theoretical concern based on how these compounds are processed, not something proven in studies, so I wouldn't lose sleep over it. CBD product quality also varies a lot. If you plan to use both, just loop in your pharmacist or your neurologist who manages your Skyclarys so they can keep an eye on things.

About Cannabidiol (cbd)

What is Cannabidiol (cbd)?

  • Anxiety and stress
  • Sleep problems
  • Chronic pain
  • Certain seizure disorders
  • Inflammation

CBD is a compound from the cannabis (hemp) plant that does not cause a 'high.' It has strong evidence only for certain rare seizure disorders (as a prescription drug), while most other popular uses are still backed by limited or early research. Product quality varies a lot, so talk with your pharmacist or doctor before using it, especially if you take other medicines.
