Benzodiazepines & other targeted substances
What laws and guidelines must pharmacists follow?
The Benzodiazepines and Other Targeted Substances Regulations were lawfully established September 1, 2000. The registrars of NAPRA’s Inter-provincial Pharmacy Regulatory Committee (IPRC) in conjunction with the Canadian Society of Hospital Pharmacists (CSHP) developed model guidelines to achieve a consistent application and understanding of this federal legislation and to assist pharmacists in complying with the requirements of the regulations in community and institutional practices. These guidelines were also reviewed by Health Canada’s Office of Controlled Substances, and were approved by NAPRA’s council in 2001 and were adopted by ACP Council on May 2, 2002.
Notwithstanding provincial rules permitting the advertising of drugs, Targeted Substances cannot be advertised to the general public.
Any loss or theft of a targeted substance must be reported to the federal Minister of Health within 10 days of discovery and a copy of the report is to be forwarded to the provincial or territorial pharmacy regulatory authority. Loss or Theft Report Form for Controlled Substances and Precursors forms are available to download or through the federal Office of Controlled Substances, Compliance, Monitoring and Liaison Division, Address Locator 3502B.
- Pharmacists receiving targeted substances
Pharmacists receiving targeted substances from a licensed dealer, another pharmacy, or hospital must keep a record (either in a register or an invoice record system) showing the brand name, quantity (where applicable including package size and number of packages), strength, the name and address of the supplier, and the date it was received. The record must be kept for a minimum of two years or longer if required by provincial pharmacy legislation.
In the hospital setting, only a pharmacist or practitioner practising in the hospital and authorized by the person in charge of the hospital may order a targeted substance on behalf of the hospital.
Targeted substances received by the community pharmacy, hospital pharmacy department or nursing unit must be stored in a secure environment.
- Pharmacists’ prescription records
Pharmacists are required to keep on file all written prescriptions and a written record of verbal prescriptions for two years from the last filling date. (Provincial or territorial rules may require that the record be retained longer.) Prescriptions for targeted substances may be filed in the regular prescriptions and not in the separate file created for narcotic and controlled medications.
The regulations do not specifically require that, in hospitals
- all issues of targeted substances to and returns from nursing units be recorded;
- the receiving nursing unit signs for the receipt of targeted substances;
- the recording of administered doses to patients be on a document other than the Medication Administration Record (MAR); or that
- a dose which is not administered to the patient, but returned to stock, be documented.
- Prescription refills
The pharmacist can refill a prescription for a targeted substance where refills are authorized by the practitioner and the pharmacist makes documentation at the time of the refill. Refills must be provided in accordance with the interval that may be specified on the prescription.
A prescription cannot be refilled one year after the date on the prescription regardless of remaining refills.
- Prescription transfers
With targeted substances, a pharmacist may transfer the remaining refills of a prescription to another pharmacist in another pharmacy. Section 54 prohibits the further transfer of the prescription once it has been received at a second pharmacy. The pharmacist receiving the transferred prescription may not transfer remaining refills.
- Prescribers of targeted substances
Only a licensed nurse practitioner, podiatrist, physician, or dental or veterinary practitioner can prescribe targeted substances.
- Destruction of targeted substances
If the pharmacist deems it appropriate to destroy targeted substances, records including the name, strength per unit, and quantity of the targeted substance destroyed must be kept for two years, or longer if required by provincial or territorial pharmacy legislation.
The destruction must render the product unusable, and it must be witnessed by another health care professional. An exemption is made for hospital practice where a hospital employee who is a health care professional, may destroy an opened ampoule containing amounts of a targeted substance without a witness.
- “Double-doctoring” and possession
As described in Section 4 of the Controlled Drug and Substance Act, “double-doctoring” and rules for possession apply for targeted substances.
- Exporting targeted substances
The regulations prohibit the exportation of targeted substances by pharmacists, including through the mail, pursuant to a prescription for a patient residing outside Canada.
