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.
How it is classified

The Anatomical Therapeutic Chemical code records the body system a medicine acts on and its chemical grouping. It is not a statement of what this medication treats, and nothing on this page is. For the full classification of V03AN20, see the WHO ATC/DDD Index.
