How long will you be staying?
Approximately how many different medications will you be bringing?
Approximately how many pills in total?
Are any medications in a potentially restricted class? Specifically pain medications?
I can't see any issues assuming reasonable amounts, backed with doctor's letters and prescriptions.
Obviously I wouldn't pack life-affecting medications in my checked bags, as they might prove challenging to replace.
Have you encountered any issues traveling elsewhere with these meds?
