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

Anatomical main group
Respiratory system
ATC code
R06AA02

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 R06AA02, see the WHO ATC/DDD Index.

Recalls and safety alerts

Recall matching is not available yet.

RxMonitor does not yet match Health Canada recalls to individual products — that arrives in a later release. Nothing on this page should be read as confirming that this medication has not been recalled.

Important:

Information only — this is not medical advice. RxMonitor shows what Health Canada and provincial drug programs have published about authorised products. It does not tell you what to take, whether a medication is right for you, or what dose to use.

Always talk to a pharmacist or physician about your own medication, and never start, stop or change one based on what you read here.
