How to Store Wegovy (Semaglutide)?

If you’ve recently been prescribed Wegovy (Semaglutide) for weight loss, it's essential to know how to store it. Storing semaglutide injections correctly ensures they remain effective and safe, allowing you to get the most from your obesity management medication.

This brief guide will thoroughly explore the storage guidelines for semaglutide and the importance of proper Wegovy storage. So, let’s get to the bottom of it: How to Store Wegovy injections (Semaglutide)?

Optimal Temperature for Storage

Below are the storage guidelines for semaglutide, as provided by the manufacturer, according to the patient information leaflet.

Before Use

Wegovy should be stored in the refrigerator, between the temperatures of 2°C and 8°C. It should not be stored near the freezer or allowed to freeze.

During Use

Once you have started using Wegovy, it can be stored at room temperature. It should never be stored above 30°C. You can still store your Wegovy pen in the refrigerator if you prefer, but it should be kept away from the cooling element.

How Long Does Semaglutide Last in the Refrigerator?

When semaglutide is stored in the refrigerator, it will remain stable until the expiration date. Wegovy must be discarded 6 weeks after it has been opened. Each pen should only last 4 weeks, so this shouldn’t be an issue unless you stop taking Wegovy or miss several doses.

You should not use Wegovy if the solution appears cloudy or coloured. Speak to your doctor if this happens.

Avoiding Common Mistakes in Storing Semaglutide (Don'ts)

• Do not leave it in direct sunlight or natural light
• Do not move it in and out of the refrigerator or store it in an area with fluctuating temperatures
• Do not leave the needle attached after each injection, as this could be dangerous and pose an infection risk

Keeping Wegovy at the same temperature and in the same place is the best way to store it. Try storing Wegovy in a cupboard, outside the reach of children or vulnerable adults.

Storing your Wegovy pen in its original packaging will protect it from light sources. Don’t forget to put it back after you’ve taken your weekly dose.

You should never freeze Wegovy. If it becomes frozen, do not use the pen, even after defrosting it.

Conclusion

Storing Wegovy (Semaglutide) correctly is the best way to ensure its efficacy as a weight-loss medication. The ideal place to store Wegovy before you've opened it is in the refrigerator. Once opened, store it away from light in its original packaging at a temperature below 30°C.

Each Wegovy pen will have an expiry date, but once opened, it will last 6 weeks. As each pen contains four once-weekly doses, it should be finished within 4 weeks. Check the medication through the window on the Wegovy pen before using it each time to ensure it's not cloudy or coloured.

For the most accurate advice on the storage and use of Wegovy, consult a healthcare professional or prescriber. For more information on weight loss management and obesity treatments, explore Wegovy’s FAQs and PrescriptionDoctor’s additional resources and support.
