Flying long haul with Mounjaro (Caribbean to UK) - should pen & sharps go in hand luggage or hold luggage?

[Pumpernickelbrakes]

I’m about to go the airport and I don’t know where/how to pack 4 + weeks of MJ. Please can you advise? Thank you

Hand luggage for both, the same as if it were an insulin pen and needles.

Definitely hand luggage as it risks freezing in the hold!

Absolutely hand luggage. All airlines advise that you should take any medications in hand luggage.
