Keeping your Wegovy or Mounjaro pen refrigerated - storage safety
For the majority of medicines, you can store them in your kitchen cupboard, out of reach from curious children’s hands, cool, dry and forgotten until you need them.
But for weight loss injections, it isn’t as simple as storing your paracetamol or supplements.
Weight loss treatments, like Mounjaro (tirzepatide) and Wegovy (semaglutide), don't come cheap. That’s why it’s so important you know how to store them correctly to prevent you from wasting your precious pens.
In this guide, we’ll explain how to store your Mounjaro or Wegovy pen, how to tell if it’s safe for use, and what to do if it gets warm during shipping.
How to store your Mounjaro or Wegovy pen
Firstly, you should keep your tirzepatide weight loss injection or semaglutide weight loss injection refrigerated. Store your pen in its original packaging to shield it from the light. Avoid freezing the pen, as this can harm it.
Since the pens have delicate glass parts, handle them carefully, especially after a drop on a hard surface. In such cases, use a new pen for injections.
Be mindful of varying temperatures in your fridge, and always check the pen to ensure it hasn't frozen before using it. To avoid this, it’s recommended that you store your pen in the door rather than at the back of the fridge.
This simple routine helps to maintain the pen's effectiveness and ensures safe administration.
The best storage temperature for your weight loss injection
We’ve made it clear that you should keep Mounjaro and Wegovy refrigerated, but what’s the best storage temperature for your pen?
Keep the temperature in your fridge between 2 and 8°C. If you store your pen in a fridge cooler than 2°C, the medicine could freeze, making the pen unusable.
Going on holiday? Don’t worry! Mounjaro can be stored at room temperature for up to 30 days, and Wegovy for up to 42 days. Just make sure the temperature doesn’t rise above 30°C and that you keep your pen in its original packaging to protect it from light.
However, if you’re flying, it’s a good idea to pack it in your carry-on since the baggage hold on the plane can plummet to below-freezing temperatures.

How long does Mounjaro and Wegovy last in the fridge?
How long Mounjaro and Wegovy last in the fridge depends on the pen's expiration date. If your pen expires before you’ve had a chance to use it, you should speak to your prescriber for advice.
To prevent this, you should only order what you need. For both Mounjaro and Wegovy, you will need one pen per month, which you will inject once per week.
Do not use the pen if it’s expired, and make sure you safely discard your pen and needle into a sharps bin to prevent harm to either yourself or others, in addition to avoiding cross-contamination.
Thankfully, if your pen has been unopened and refrigerated, it can last for up to 2 years, but it depends on the expiry date on the stock the manufacturer supplied when you obtained your pen.
How to tell whether your weight loss pen is safe to use
You should always check the contents of your pen before injecting it to ensure that it’s safe for use.
Inspect the pen to ensure it's not damaged and that the medication is clear without particles or cloudiness. Confirm that it's not frozen and that the colour ranges from colourless to slightly yellow. Check the expiration date to ensure it hasn't passed.
Has your Mounjaro pen been unrefrigerated for over 30 days, or your Wegovy pen for over 42 days? If so, your pen isn’t suitable for use. If you’re unsure whether your pen is safe to use, always speak to your prescriber for advice before you decide to inject.
What to do if your weight loss pen gets warm during shipping
Before you get your pen, it's stored in a fridge at your pharmacy and kept at the right temperature. The delivery process maintains this temperature by using special packaging to stop your pen from getting too warm during shipping.
We know your weight loss treatment is important to you, so we take every precaution to ensure your pen reaches you in excellent condition. Being ready to receive your delivery prevents delays and keeps your weight-loss pen from being out of the fridge for too long.
It's essential to follow the guidelines for storing your tirzepatide or semaglutide pen to ensure its effectiveness and your safety. Checking for damage, any signs of freezing and confirming that it isn't expired is crucial.
