Ontario Drug Benefit coverage
As of 31 July 2026This 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.
