Yes, but only if permitted under a section 56 exemption to the Controlled Drugs and Substances Act. The pharmacist may use their professional judgement to determine if they have the appropriate knowledge and if it is in the patient’s best interest to do so. If they are comfortable with their assessment, they can make the decision to provide an adapted renewal of a narcotic, controlled drug or targeted substance for a duration up to, but not exceeding, the duration originally prescribed.
This only applies to adapted renewals. A pharmacist must not perform other adaptations on narcotic, controlled drug or targeted substances which include changing the dose, formulation or regimen, and making a therapeutic substitution.
