Have you recently got your hands on Mounjaro? Or are you planning to get started with this medication? If so, you probably want to know how to store it correctly. 

We’ve got you covered. Read on to learn all about Mounjaro storage, including: 

  • How to Store New Mounjaro Pens 
  • How to Store Used Mounjaro Pens
  • How Long Can Mounjaro Be Out of The Fridge? 
  • How Do I Know If My Mounjaro Has Gone Bad? 
  • Mounjaro Storage Dos and Dont’s
  • How to Travel With Mounjaro 

How to Store New Mounjaro Pens 

New Mounjaro KwikPens should be kept in the fridge, at temperatures ranging between 2°C to 8°C. Choose a spot in the fridge near the front – this will help to prevent the pens from freezing. If you find that your pen has frozen, you should discard it immediately. 

Some people store their unused Mounjaro pens in special cosmetic fridges, as this means they won’t be around food. Cosmetic fridges may also be less likely to accidentally freeze your Mounjaro (which can render the medication ineffective). 

Keep your unused Mounjaro pens in the fridge until they expire (see expiration date on the label). Be sure to always check the expiry date and never use a pen past its date. 

How to Store Used Mounjaro Pens

When you’ve used your Mounjaro KwikPen, you can either store the pen at room temperature or in the fridge.

If storing at room temperature – keep the pen at temperatures no higher than 30°C for no more than 30 days. 

If storing in the refrigerator – Place it back in the fridge at temperatures between 2°C to 8°C. 

Whichever storage option you choose, make sure you always keep the pen in the box to shield it from light and keep the cap of the pen attached. 

How Long Can Mounjaro Be Out of The Fridge? 

You can keep Mounjaro out of the fridge for a maximum of 28 days – as long as the room temperature does not exceed 30°C or drop below 2°C, and as long as your injection pen cap remains on.

How Do I Know If My Mounjaro Has Gone Bad?

If you suspect your Mounjaro has gone bad, throw it away. Do not use it – using expired or improperly stored medication can be ineffective, and in some cases, harmful. Here’s how you might be able to tell if your Mounjaro has gone bad: 

  1. Check the expiration date – if it’s out of date, throw it away! 
  2. If it’s been stored in warm temperatures above 30°C
  3. If you’ve left it out of the fridge for 21 days (unopened) or 30 days (opened) 
  4. If it’s been frozen 
  5. If the liquid isn’t clear/ looks cloudy
  6. If there are particles in the liquid
  7. If the liquid looks discoloured 
  8. If the pen appears damaged 
  9. If the packaging has been tampered with 

If you’re not sure whether you should take your Mounjaro pen or throw it away, speak to us at Dr Franks. We can help you determine whether your Mounjaro from Dr Frank’s Weight Loss Clinic has gone bad or not.

How to Travel With Mounjaro 

Whether you’re going on a long holiday or a short weekend away, it’s important to keep your Mounjaro safe. Here’s how: 

  • If you're flying with Mounjaro, keep it in your carry-on luggage – do not pack it into your checked case. 
  • Make sure you keep your pens in their original packaging to protect it from light. This will also make it easier for airport security to identify your medication.
  • Use a cool bag, but do not place Mounjaro directly on ice packs as this can lead to your Mounjaro pen freezing. 
  • Avoid placing your medication in the boot of your car, as this is where temperatures fluctuate the most.
