Canada \u00b7 Comparison

Ozempic vs Wegovy in Canada: what actually differs.

“Ozempic vs Wegovy Canada” is about indication, coverage and which brand (or generic) a Canadian prescriber might choose — not which is “better.” Both are authorized semaglutide products.

Indication (Health Canada)

Ozempic — type 2 diabetes.
Wegovy — chronic weight management (with diet and activity) in eligible patients.
Using either off-label is a clinical decision for a licensed prescriber — we don't advise it.
