Is DXM legal in Canada?

Also known as: robo, dextromethorphan

Legal status

Over-the-counter, non-prescription drug. Single-ingredient dextromethorphan (DXM)/DXM hydrobromide antitussives are sold under Health Canada's non-prescription adult antitussive labelling standard (maximum 120 mg per 24 h) with a Drug Identification Number; DXM is not scheduled under the Controlled Drugs and Substances Act (CDSA).

Consequences if caught

No CDSA controlled-substance offence; supply must meet the non-prescription labelling standard, and non-compliant products are a Food and Drugs Act matter. Section 60 of the Controlled Drugs and Substances Act lets the Governor in Council by order amend any of Schedules I to IV, VI and IX by adding or deleting an item, if the Governor in Council considers the amendment necessary in the public interest. The consolidation read states on its face that it is current to 21 July 2026. An absence is only ever an absence as at the version read, and this cell does not rule out a later amendment.

If prescribed or medical

Cough-suppressant status: OTC non-prescription drug (labelled maximum 120 mg per 24 h).

Documentation

DXM cough medicine is sold on pharmacy and retail shelves in Canada without a prescription.
