Does Mounjaro Need To Be Refrigerated?
Mounjaro should normally be stored in a refrigerator before use. The recommended storage temperature is between 2°C and 8°C.
Keeping the medication refrigerated helps preserve the stability of the active ingredient tirzepatide and ensures the pen delivers the correct dose. However, there are certain situations where temporary storage outside the refrigerator may be possible.

- Store unused pens in a refrigerator between 2°C and 8°C
