Clobazam and Cannabidiol Interaction
Drug interaction information between Clobazam and Cannabidiol.
Clobazam and Cannabidiol have a documented moderate interaction in FDA labeling.
FDA drug labeling documents a moderate-severity interaction between Clobazam and Cannabidiol. Major interactions are generally avoided, moderate ones may need monitoring or a dose adjustment, and minor ones are usually low-risk. This page shows the documented mechanism and guidance. Label-documented interactions are not a complete safety review, so always confirm your own medications with a pharmacist or doctor. Educational information, not medical advice.
How They Interact
Cannabidiol increases the amount of an active byproduct of clobazam in your blood, which can lead to more side effects.
What To Do
If you experience increased side effects, your doctor may need to reduce your dose of clobazam.
FDA Label Information
7.2 Effect of EPIDIOLEX on Other Drugs Antiepileptic Drugs Clobazam Concomitant use of EPIDIOLEX with clobazam increases plasma concentrations of N‑desmethylclobazam, the active metabolite of clobazam [see Clinical Pharmacology ( 12.3 )], which may increase the risk of clobazam-related adverse reactions [see Adverse Reactions ( 6.1 ) and Warnings and Precautions ( 5.1 , 5.2 )]. Consider a reduction in dosage of clobazam if adverse reactions known to occur with clobazam are experienced when concomitantly used with EPIDIOLEX.

Frequently Asked Questions
Can I take Clobazam and Cannabidiol together?
This is a moderate interaction. If you experience increased side effects, your doctor may need to reduce your dose of clobazam.
How serious is the interaction between Clobazam and Cannabidiol?
This interaction is classified as "moderate" severity by the FDA. Moderate interactions may worsen your condition or change how your medications work.
Why do Clobazam and Cannabidiol interact?
Cannabidiol increases the amount of an active byproduct of clobazam in your blood, which can lead to more side effects.
Understanding the Clobazam and Cannabidiol Interaction
FDA-approved prescribing information for these two drugs flags their combination as a moderate-severity interaction. Clobazam belongs to the Benzodiazepine (Anticonvulsant) class and Cannabidiol belongs to the Cannabinoid (Anticonvulsant) class - two categories that can collide when co-prescribed. The mechanism described in FDA labeling is: Cannabidiol increases the amount of an active byproduct of clobazam in your blood, which can lead to more side effects. Severity tiers matter: major flags generally advise avoidance, moderate flags often require monitoring or dose adjustment, and minor flags may only call for awareness.
Context around a specific patient determines real-world impact. Clobazam has 6 total documented interactions on file in this dataset, and Cannabidiol has 8. Each additional medication compounds the interaction surface, which is why pharmacists run full-profile checks rather than evaluating one pair at a time. FDA-derived guidance for this pair is: If you experience increased side effects, your doctor may need to reduce your dose of clobazam. Timing of doses, renal and hepatic function, age, and other concurrent prescriptions all shape whether a labeled interaction matters clinically.
An interaction flag is not a verdict. A large share of labeled interactions are managed routinely in clinical practice, the fix may be as simple as spacing doses or adding a monitoring test. Others require the prescriber to choose a different medication entirely. This page surfaces FDA-sourced labeling and openFDA data for educational purposes only; it is not medical advice and cannot account for your full clinical picture. Never start, stop, or adjust either Clobazam or Cannabidiol based on a web page, speak with your prescriber or pharmacist before making any change.
