How does this medication work? What will it do for me?

Semaglutide belongs to a group of medications known as glucagon-like peptide-1 (GLP-1) receptor agonists. It is used alone or with other medications to improve blood glucose (sugar) levels for people with type 2 diabetes.

Diabetes medications such as semaglutide are used when diet, exercise, weight reduction and medications such as metformin, glyburide, or insulin have not been found to lower blood sugar well enough on their own. It works by helping your body make more insulin and control blood glucose levels.

This medication may be available under multiple brand names and/or in several different forms. Any specific brand name of this medication may not be available in all of the forms or approved for all of the conditions discussed here. As well, some forms of this medication may not be used for all of the conditions discussed here.

Your doctor may have suggested this medication for conditions other than those listed in these drug information articles. If you have not discussed this with your doctor or are not sure why you are taking this medication, speak to your doctor. Do not stop taking this medication without consulting your doctor.

Do not give this medication to anyone else, even if they have the same symptoms as you do. It can be harmful for people to take this medication if their doctor has not prescribed it.

What form(s) does this medication come in?

Each 1 mL of clear, colourless solution contains 1.34 mg of semaglutide. Nonmedicianl ingredients: disodium phosphate dihydrate, propylene glycol, phenol, and water for injections.

There are 2 forms of the pre-filled, multi-dose, disposable pen. One pen delivers doses of 0.25 mg and 0.5 mg semaglutide, while the other pen delivers 1 mg doses only.

Each pen contains 2 mg of semaglutide.

How should I use this medication?

The recommended adult starting dose of semaglutide is 0.25 mg once a week. Semaglutide is injected subcutaneously (under the skin) on your stomach area (abdomen), upper thigh, or upper arm, exactly as instructed by your doctor or diabetes educator. It can be injected at any time of the day, without regard to meals. After four weeks, your dose will increase to 0.5 mg once a week. If needed, your doctor may increase the dose again in four weeks to 1mg once a week. Do not change your dose unless your doctor has told you to do so.

If you are also using insulin, each medication should be injected separately.

Your doctor or diabetes instructor will show you how to use this medication properly. If you are not sure how to use it or have questions about how to use it, contact your doctor. Before using this medication, thoroughly read the patient information provided and ask your doctor if you have any questions. If a caregiver will be giving you the injections, your doctor should instruct them on how to give the injection.

Many things can affect the dose of medication that a person needs, such as body weight, other medical conditions, and other medications.

If you miss a dose, and it is less than 5 days since the missed dose, inject your dose as soon as possible. If it less than 48 hours until your next scheduled dose, skip the missed dose and continue with your regular dosing schedule. Do not inject a double dose or increase your dose to make up for a missed one. If you are not sure what to do after missing a dose, contact your doctor or pharmacist for advice.

Semaglutide should be clear and colourless. Do not use semaglutide if you notice particles or anything unusual in the appearance of the solution.
