Weight loss prescriptions Canada: where to start and what to expect

Looking for prescription options to help lose weight in Canada? You’re not alone. Newer drugs have changed what’s possible, but getting them safely matters as much as the medication itself. This page explains how to qualify, where to get prescriptions, how much you might pay, and smart ways to avoid scams.

Who usually qualifies and how doctors decide

Most clinicians follow simple rules: a BMI of 30 or higher, or a BMI of 27+ with a related health problem (type 2 diabetes, high blood pressure, sleep apnea). Your doctor will also review your medical history, current meds, and whether weight-loss drugs are safe for you. Bring a list of medications, recent weight and height, and any lab results. Expect questions about prior diets, exercise, and mental health—your doctor needs the full picture to pick the right option.

Common prescription classes include GLP-1 drugs (like semaglutide) and newer combo agents. Some were first approved for diabetes and later for weight management. Dosing and monitoring matter: most start low and increase over weeks to limit side effects like nausea or constipation. If you have diabetes, your doctor will watch blood sugar closely.

Where to get a prescription and how to avoid risks

Start with your family doctor. If that’s not an option, look for certified obesity clinics or regulated telehealth services in Canada. These services connect you with licensed prescribers who can assess you and provide local pharmacy prescriptions. Always get a written prescription and have your pharmacist review interactions.

Be careful with online sellers that offer drugs without a valid prescription or that ship from unknown sources. Fake or mishandled medications can be dangerous. Use a licensed Canadian pharmacy or a well-known pharmacy chain. If an online price seems too good to be true, it probably is.

Price can be a shock. Provincial drug plans sometimes cover these meds for specific patients, and private insurance may help. Ask your prescriber if there are patient-assistance programs from manufacturers or coupons you qualify for. Comparing pharmacy prices and asking about 90-day dispensing or biosimilars can cut costs too.

Follow-up is part of the deal. Good care includes check-ins for side effects, dose adjustments, and monitoring of weight and labs. If you stop the medication, weight can return, so discuss a long-term plan with your provider—lifestyle support, dietitians, and behaviour programs make the benefits last longer.

If you want help preparing for a visit, print your weight history, list of meds, and a short summary of your goals. That makes appointments faster and more productive. Ask questions: how long until I see results, what side effects to expect, and how costs will be handled. A clear, honest conversation saves time and keeps you safe.
