Dextromethorphan's classification changes depending on package size. What is the unscheduled limit for oral dosage forms?

Dextromethorphan is a common active ingredient used in many over-the-counter cough and cold medications. In Canada, the classification of certain substances can depend on the amount contained within a product's package. Specifically for dextromethorphan in oral dosage forms, the unscheduled limit—meaning it can be sold without a prescription—in Saskatchewan is set at 300 mg.

This limit allows for consumer access to medications in quantities deemed safe for self-administration without the need for consultation with a healthcare professional. Products containing dextromethorphan are categorized differently above this threshold, which indicates a regulatory measure to prevent misuse or adverse effects that can occur from higher dosages.

By understanding this classification rule, pharmacy professionals can ensure compliance with Saskatchewan's pharmacy laws and appropriately advise consumers on the use and availability of products containing dextromethorphan.
