Saxenda vs Ozempic

If you’ve been hearing about “Ozempic weight loss” and “Saxenda pens,” you’re not alone. Here’s the simple guide to Saxenda vs Ozempic in Ontario.

Saxenda vs Ozempic for Weight Loss: Which Is Better?

Saxenda (liraglutide) is approved in Canada for chronic weight management with diet and physical activity, for adults with obesity (BMI 30 or higher) or overweight (BMI 27 or higher) plus at least one weight-related condition.
Ozempic (semaglutide) is approved in Canada for adults with Type 2 diabetes to improve blood-sugar control and for certain cardiovascular and kidney risk indications in Type 2 diabetes. Weight loss can happen, but it is not the main reason for taking Ozempic.

Wegovy is a semaglutide that is labelled for weight loss

In clinic trials, liraglutide 3.0mg led to an average of 8 per cent weight reduction over 56 weeks, while semaglutide 2.4mg led to an average 14.9 per cent reduction over 68 weeks. Ozempic’s diabetes trials also report weight loss (about 4.8kg at 56 weeks with 1mg once weekly).
Ontario access to these medications differs by label. The Ontario Drug Benefit Formulary/Comparative Drug Index lists Ozempic as a Limited Use product with criteria tied to Type 2 diabetes, not “weight loss alone.”

Saxenda vs Ozempic Side Effects and Safety

There are many overlapping side effects between Saxenda and Ozempic. Nausea, vomiting, diarrhea, and constipation are common, especially during dose increases, and GI (gastrointestinal) symptoms are common reasons people stop treatment.

Saxenda vs Ozempic Cost in Ontario

Totals of Saxenda and Ozempic can vary by markups, dispensing fees, and insurance.
A B.C. Ministry of Health academic detailing table estimated Saxenda’s approximate annual cost at about $5 600 at maintenance dosing (before markups and professional fees). For Ozempic, the formulary lists a unit price of $227.94, depending on the pen sizes which affects how long the pen lasts.
Coverage is separate from price. The Canadian Medical Association and Obesity Canada both note that public plans, most of the time, do not cover obesity medications, and Ozempic coverage in Ontario is linked to diabetes criteria.
