Injectable semaglutide treatment support: week 1

Injection guide: week 1

Using your pen, inject one dose of 0.25 mg once this week.We recommend keeping track of your injections and doses each week by recording them in your calendar.

For instructions on how to use your pen, refer to the treatment guide provided with your medication or speak to your pharmacist.

Where to inject

Inject into the lower stomach area, about 1-2 inches away from the navel. This is usually easiest and ensures the medication gets absorbed into your bloodstream quickly. Other good injection sites include upper legs (thighs) and upper arms.

You should choose a new injection site each week, leaving 1-2 inches between sites to avoid irritation.

How to store your medication

To remain stable and effective, the medication in your pen must remain between 2 to 30°C. If the temperature in your home exceeds this range, it’s best to store your pen in the fridge.

The medication will be stable for up to 56 days after it’s been dispensed if stored within the given range.

How to check the medication in your pen

You can view your medication through a window on the side of the pen. The liquid in your pen should be clear.

If the liquid isn't clear or you notice anything floating in it, stop taking it and contact your pharmacy as it may be spoiled.
