Yes, you can take Mounjaro on a plane. It is recommended to carry it in your hand luggage along with the needles and a cooling case or ice pack to keep it at the correct temperature. Make sure to keep the pen in its original packaging, carry your prescription or a doctor's note, and declare it at airport security if asked. Mounjaro should not be packed in checked luggage because of temperature and pressure changes that may affect the medication. X-ray scanners at security do not affect Mounjaro. It is also advised to check the regulations of the country you are visiting regarding medication import, and if needed, have documentation translated into the local language. Keep your dosing schedule in mind, especially if crossing time zones.
