Why this term matters

Patients often confuse off-label with illegal.

UK medical cannabis context

NICE’s explanatory material around prescribing notes that guidance includes information about prescribing medicines, including off-label use.

What not to assume

Off-label use requires clinical judgment and informed discussion; it is not casual experimentation.

Careful wording: Avoid normalising off-label use as routine consumer choice.
