Mounjaro (tirzepatide) is one of the most effective weight-loss treatments available in the UK, but like all injectable medicines, it must be stored correctly to remain safe and effective. If Mounjaro pens are not kept at the right temperature, the medicine can lose its potency. Here’s everything you need to know about storing Mounjaro pens safely at home and while travelling.
How Should Mounjaro Be Stored?
Before use, Mounjaro pens should be stored in the fridge at 2°C to 8°C. Do not freeze them, and avoid placing them directly against the cooling element at the back of the fridge.
Once in use, an unopened pen can be stored at room temperature (below 30°C) for up to 21 days, but it must be protected from direct sunlight and heat sources.
Why Storage Matters
If Mounjaro is stored incorrectly, it may:
- Lose effectiveness, reducing weight-loss results
- Become unsafe to inject
- Expire faster than the recommended shelf life
Correct storage ensures every injection delivers the full intended dose.
Tips for Safe Storage at Home
- Keep pens in their original packaging until ready to use
- Store them in the middle shelf of your fridge, not the door
- Always check the expiry date before use
- Never use pens that have been frozen or overheated
Storing Mounjaro While Travelling
For trips, Mounjaro can be safely transported in a cool bag, insulated pouch, or travel fridge. Once you arrive, store pens in a refrigerator if possible. If travelling to hot climates, avoid leaving pens in cars, direct sunlight, or uncooled luggage.
