Always ensure that any medication required for your flight and subsequent journey is packed in your carry-on luggage. This should be accompanied by additional prescription documents and letters from your doctor detailing your medication requirements.

If your medication necessitates a specific temperature, it should be packed in a cooler bag for onboard transport. Avoid removing your medication from its original packaging - it’s preferable to keep it in its box with the pharmaceutical labels clearly visible.

For those who need medication administered via a syringe, medical sharps can typically be brought onboard with minimal issues. However, you may need to provide a doctor’s letter, a prescription, or the medication itself with the pharmacy label showing your name.

It is always best to check with the airline or cruise line you are travelling with in relation to their individual policies.
