Products with the same active ingredient

Grouped by Health Canada’s active-ingredient group number. Products in a group do not always share a strength — check the strength above against your own. Sharing an active ingredient does not mean two products can be substituted for each other: whether a substitution is permitted is a provincial decision, and this page does not show it. Ask a pharmacist.

Ontario Drug Benefit coverage

As of 31 July 2026

This medication is not listed on the Ontario Drug Benefit formulary.

Not on the formulary is not the same as not covered. Private and workplace insurance, federal programs such as Non-Insured Health Benefits and Veterans Affairs, and every other province’s public plan are all outside what this page shows — Ontario is the only province RxMonitor holds coverage data for. Ontario may also fund a product that is not on the formulary through the Exceptional Access Program.

Information only — this is not medical advice. RxMonitor shows what Health Canada and provincial drug programs have published about authorised products. It does not tell you what to take, whether a medication is right for you, or what dose to use.

Always talk to a pharmacist or physician about your own medication, and never start, stop or change one based on what you read here.
