What should I do if my Mounjaro pen freezes during travel?

If your Mounjaro pen freezes during travel, discard it immediately and do not use it, even if it thaws. Replace it with a new pen that has not been frozen. Contact your healthcare provider or pharmacist for advice on getting a replacement.

Key points:

  • Freezing damages the medication's effectiveness and pen mechanism.
  • Check for signs like crystals, cloudiness, or unusual thickness in the liquid.
  • Do not attempt to use or inject from a frozen pen.
  • Always store at 2°C to 8°C or up to 30°C (after opening) for a limited time, never freezing.
