How Long Does a Wegovy Pen Last?

Wegovy is a prescription-only injection for overweight and obese adults. Like with any medication, if you’re looking to use Wegovy as part of your weight loss program, you may be wondering how long a Wegovy pen will last.

The pen is pre-filled with 4 doses, so each pen will last for 4 weeks. In this article, we’ll explore how long each pen lasts and the dosage schedule in more detail.

How long does a Wegovy pen last?

Each Wegovy pen contains 4 doses of medication at the prescribed strength. Because Wegovy is injected once per week, each pen will last for 4 weeks, and each dose will last for a few days. In total, there are 5 different doses. 

When you first start Wegovy, you’ll be prescribed the lowest dose, which will increase every 4 weeks until you reach the maintenance dose of 2.4 mg per week or whichever dose is most suited to you.

The dosage schedule is usually:

What is the Wegovy maintenance dose?

Although everyone will start at the lowest dose, the maintenance dose will not always be 2.4mg per week. Some people may prefer to stick to the lower 1.7mg per week dose as their maintenance dose.

It may be better to stick to the lower dose if you experience side effects or are finding it effective. Your clinician will discuss with you which dose should be your maintenance dose.

How long should the first Wegovy pen last me?

Each pen contains 4 prefilled doses, so each pen will last for 4 weeks.

Can I increase my dose early?

No, you should not increase your Wegovy dose early unless your clinician has advised you to. Increasing your dose early could cause side effects.

How long does a Wegovy pen last at the maintenance dose?

Whether you are prescribed a maintenance dose of 1.7 or 2.4 mg per week, each pen will last for four weeks.

While you remain on the maintenance dose, you will need a new pen every 4 weeks to continue with your dosage schedule.

How long can you store a Wegovy pen for?

How to store your pen will depend on if you have started using the pen.

Before using your Wegovy pen you should store the unused injection in its box in a fridge. The ideal fridge temperature should be between 2 and 8 degrees Celsius.

The Wegovy pen can be stored for up to 6 weeks when in use. The Wegovy pen can be stored below 30 degrees Celsius or in a fridge at a temperature between 2 and 8 degrees Celsius.

If you’re unsure about how to store your Wegovy pen, read the patient information leaflet.
