Lowest DBP recovery rule under medically necessary no-substitution claims:
6.2 Medically Necessary "No Substitution" Claims
The Side Effect Reporting Form will not have to be renewed. However, the
pharmacy must maintain a copy of the prescription that contains a direction that
there be no substitution and the required Health Canada Side Effect Reporting Form
(completed and signed by the prescriber). The prescriber must write “No
Substitution” or “No Sub” on renewal or subsequent new written prescriptions, and
indicate “No Substitution” on subsequent new oral prescriptions. The dispenser will
be reimbursed the DBP plus a mark-up and the lesser of the posted usual and
customary fee or the ODB dispensing fee minus the applicable ODB co-payment
amount. Where a completed Side Effect Reporting Form is not available at the
pharmacy during an inspection, the difference between the cost of the higher-cost
product and the lowest DBP listed for the interchangeable category will be
recovered.
(ontario.ca, Revision #17; 2026-08-03 ↗)
6.2 Medically Necessary "No Substitution" Claims
The Ministry will provide reimbursement of a higher-cost interchangeable product in
medically necessary circumstances where a patient has experienced a significant
adverse reaction with two (2) lower-cost interchangeable drug products, where
available. When a prescriber identifies a patient for which it is medically necessary
that a higher cost interchangeable product be provided, the prescriber must:
• Complete, sign and forward to the pharmacist a copy of the Health Canada
side effect reporting form for each lower-cost interchangeable drug product
trialed (Side Effect Reporting Form[s]); and
• Write “No Substitution” or “No Sub” on a written prescription or indicate “No
Substitution” to the pharmacist in the case of a verbal prescription.
The prescriber should keep a copy of the completed form in the patient’s record for
future use and reference.
In the case of a written prescription, when the pharmacist or dispensing physician
receives a prescription with the written notation “No Substitution” or “No Sub”,
reimbursement will be provided for the higher-cost interchangeable product only if
the prescription is accompanied by a completed Health Canada Side Effect
Reporting Form for each of the lower-cost interchangeable drug products trialed.
This form must be completely filled out noting the details of the adverse reaction
and signed by the prescriber.
In the case of a verbal prescription, the prescriber must satisfy the operator of the
pharmacy or dispensing physician that a completed Health Canada Side Effect
Reporting Form for each of the lower-cost interchangeable drug products trialed
has been completed and signed by the prescriber. A written record of this verbal
prescription and the completed Health Canada Side Effect Reporting Form must be
received by the pharmacy prior to claim submission.
Upon receipt, the pharmacist must:
• Fax, submit online or mail the completed and signed form to Health Canada’s
Canada Vigilance Program; and
• Retain his or her copy of the completed and signed Side Effect Reporting
Form.

Lowest DBP recovery rule under medically necessary no-substitution claims:
6.2 Medically Necessary "No Substitution" Claims
The Side Effect Reporting Form will not have to be renewed. However, the
pharmacy must maintain a copy of the prescription that contains a direction that
there be no substitution and the required Health Canada Side Effect Reporting Form
(completed and signed by the prescriber). The prescriber must write “No
Substitution” or “No Sub” on renewal or subsequent new written prescriptions, and
indicate “No Substitution” on subsequent new oral prescriptions. The dispenser will
be reimbursed the DBP plus a mark-up and the lesser of the posted usual and
customary fee or the ODB dispensing fee minus the applicable ODB co-payment
amount. Where a completed Side Effect Reporting Form is not available at the
pharmacy during an inspection, the difference between the cost of the higher-cost
product and the lowest DBP listed for the interchangeable category will be
recovered.
(ontario.ca, Revision #17; 2026-08-03 ↗)
6.2 Medically Necessary "No Substitution" Claims
The Ministry will provide reimbursement of a higher-cost interchangeable product in
medically necessary circumstances where a patient has experienced a significant
adverse reaction with two (2) lower-cost interchangeable drug products, where
available. When a prescriber identifies a patient for which it is medically necessary
that a higher cost interchangeable product be provided, the prescriber must:
• Complete, sign and forward to the pharmacist a copy of the Health Canada
side effect reporting form for each lower-cost interchangeable drug product
trialed (Side Effect Reporting Form[s]); and
• Write “No Substitution” or “No Sub” on a written prescription or indicate “No
Substitution” to the pharmacist in the case of a verbal prescription.
The prescriber should keep a copy of the completed form in the patient’s record for
future use and reference.
In the case of a written prescription, when the pharmacist or dispensing physician
receives a prescription with the written notation “No Substitution” or “No Sub”,
reimbursement will be provided for the higher-cost interchangeable product only if
the prescription is accompanied by a completed Health Canada Side Effect
Reporting Form for each of the lower-cost interchangeable drug products trialed.
This form must be completely filled out noting the details of the adverse reaction
and signed by the prescriber.
In the case of a verbal prescription, the prescriber must satisfy the operator of the
pharmacy or dispensing physician that a completed Health Canada Side Effect
Reporting Form for each of the lower-cost interchangeable drug products trialed
has been completed and signed by the prescriber. A written record of this verbal
prescription and the completed Health Canada Side Effect Reporting Form must be
received by the pharmacy prior to claim submission.
Upon receipt, the pharmacist must:
• Fax, submit online or mail the completed and signed form to Health Canada’s
Canada Vigilance Program; and
• Retain his or her copy of the completed and signed Side Effect Reporting
Form.

1.1 Pediatrics
Pediatrics (<18 years of age): Safety and effectiveness in children have not been established.
No data are available to Health Canada; therefore, an indication for pediatric use has not been
authorized.

between these patients and younger patients, but greater sensitivity of some older individuals
cannot be ruled out (see 7.1.4 Geriatrics).
