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

Off-formulary interchangeable Part III-B

Ontario has designated this product interchangeable with a brand product, but it is not an ODB benefit — Part III-B, Off-Formulary Interchangeable. Ontario does not pay for it under the benefit list.

It may be funded through the Exceptional Access Program, which needs a patient-specific application from a prescriber and is decided case by case.

What ODB pays per unit
$1.7735

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.

Products Ontario considers interchangeable

As of 31 July 2026

Ontario groups these products together at 10mg Tab and will substitute one for another at a pharmacy counter in Ontario.

Ontario lists 1 further product in this group that is not currently marketed in Canada. It is 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.
