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.

When prescribing NSAIDs, the minimal effective dose for the shortest period of time should be used. In nonspecific pain and/or osteoarthritis, in the absence of joint inflammation (swelling), acetaminophen is a better first choice for analgesia. The most effective treatment to prevent NSAID-gastritis is misoprostol; although H-2 antagonists, such as ranitidine or cimetidine, are commonly used, they are not as effective. NSAIDs can significantly aggravate hypertension and congestive heart failure; ASA in doses below 1 gram per day is a better choice than other NSAID options if anti-inflammatory effects are required in patients with these conditions. Low dose ASA has additional benefits for anti-platelet indications that are not provided by other NSAIDs, and should be given in preference or in addition to other NSAIDs for patients with vascular indications.
