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 2026General benefit Part III-A
Ontario lists this product as a general benefit under the Ontario Drug Benefit program — Part III-A of the Formulary/CDI. For someone eligible for ODB, it is covered without a drug-specific approval.
- What ODB pays per unit
- $0.3147
This is what the Ontario Drug Benefit program reimburses a pharmacy for one unit, as of 31 July 2026. A deductible and a co-payment sit on top of it and differ by program — ODB, the Trillium Drug Program and the seniors co-payment each work differently — so it is not the figure anyone is charged at a counter. It also says nothing about private, workplace or federal coverage.

Ontario lists 5 further products in this group that are not currently marketed in Canada. They are not shown.
This is Ontario’s designation, under the Ontario Drug Benefit program, and it applies in Ontario. It is a different statement from the same-active-ingredient list above, which is Health Canada’s grouping and carries no substitution meaning at all. No other province’s rules are shown on this page, and a designation here is not a recommendation to switch — that is a conversation with a pharmacist or prescriber.
