- You need to drive or operate machinery
Do not combine with…
- Blood thinners and anticoagulants
- Anti-epileptic medications
- Medications metabolised by CYP3A4 or CYP2C19 liver enzymes

- Evidence may be incomplete
Interaction Warnings
Interaction concerns are shown for risk awareness only. SubsAtlas does not describe any combination as safe.
- CBD inhibits liver enzymes (CYP3A4, CYP2C19) that metabolise many common medications, potentially raising or lowering medication blood levels. This interaction potential is significant and applies to a wide range of prescribed medications. CBD is not a substitute for medical guidance, and interaction review is relevant for anyone taking prescribed medications.
