Generic semaglutide dosing schedule in Canada

Strengths and form

This page follows the product monograph of Semaglutide Injection (Dr. Reddy's Laboratories Ltd.), a generic semaglutide injection. It does not describe the generic products of other companies.

Semaglutide Injection is a solution of semaglutide for injection under the skin. It comes in a pre-filled, multi-dose, disposable pen.

Each 1 mL of solution contains 1.34 mg of semaglutide.

One carton holds 1 pen. Disposable needles are included in the package.

The product monograph lists two variants of the pen:

• A pen that delivers doses of 0.25 mg or 0.5 mg. It contains 2 mg of semaglutide.
• One unused pen of this kind contains 4 doses of 0.25 mg and 2 doses of 0.5 mg, or 4 doses of 0.5 mg.
• This pen is for dose escalation and for maintenance treatment at the 0.5 mg dose.
• A pen that delivers 1 mg doses. It contains 4 mg of semaglutide, for 4 doses.
• This pen is for maintenance treatment at the 1 mg dose only.

Starting dose and dose steps

The recommended starting dose is 0.25 mg once weekly. The product monograph says that 0.25 mg is not a therapeutic dose.

After 4 weeks, the dose should be increased to 0.5 mg once weekly.

If additional glycemic control (blood sugar control) is needed after 4 weeks, the dose may be increased to 1 mg once weekly.

If additional glycemic control is needed after 4 weeks, the dose may then be increased to 2 mg once weekly.

The patient information in the product monograph says: talk to your doctor before you increase your dose. Do not change your dose unless your doctor has told you to.

Maintenance and maximum dose

The maximum recommended dose is 2 mg once weekly. An alternative product is required for a 2 mg weekly dose.

The patient information says that your doctor will prescribe another medication if they decide that you need a 2 mg weekly dose.

The product monograph describes pens for maintenance treatment at the 0.5 mg dose and at the 1 mg dose.

No dosage adjustment is required for patients with renal insufficiency. Semaglutide Injection is not recommended for use in patients with end-stage renal disease.

The product monograph says that no dose adjustment is required based on age. Semaglutide Injection is not indicated for pediatric use (under 18 years of age).

Do not stop Semaglutide Injection without talking to your doctor. If you stop, your blood sugar levels may increase.

How and when to inject

Semaglutide Injection is given once weekly, at any time of the day, with or without meals. It should not be given daily.

The patient information says to use Semaglutide Injection on the same day each week if possible.

The day of the weekly injection can be changed if necessary. The time between two doses must be at least 2 days (more than 48 hours).

Semaglutide Injection is injected under the skin of the abdomen, the thigh or the upper arm. Do not inject it into a vein or a muscle.

The product monograph says to rotate injection sites with each dose. Do not use the same site for each injection.

Look at the solution before use. It should appear clear and colourless.

Before you use the pen for the first time, your doctor or Diabetes Nurse Educator shows you how to use it.

The product monograph says that patients should not administer the full volume of the pen at any time.

Missed dose

A missed dose should be given as soon as possible within 5 days after the missed dose.

The patient information in the product monograph gives two cases:

• It is 5 days or less since the day of the missed dose: use Semaglutide Injection as soon as you remember. Then inject your next dose as usual on your scheduled day.
• It is more than 5 days since the day of the missed dose: skip the missed dose. Then inject your next dose as usual on your scheduled day.
• In both cases: do not take an extra dose or increase the dose to make up for a missed dose.
