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 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.

Maximum Strength Acid Reducer Without prescription: NDMA impurity
Health Canada says: Talk to your doctor or pharmacist at your earliest convenience about alternative, non-ranitidine treatment options appropriate for your health circumstances. There are many prescription and over-the-counter drug alternatives in Canada that are authorized for the same or similar uses as ranitidine.Individuals taking a prescription ranitidine drug, including a recalled product, should not stop taking it unless they have spoken to their health care provider and obtained alternative treatment, as the risk of not treating the condition may be greater than the risk related to NDMA exposure.Contact your health care provider if you have taken a ranitidine product and you have concerns about your health.Report any health product adverse events or complaints to Health Canada.
