where are you going
fine thank you
This is not a requirement for the airlines, but the country you are traveling too
And for Greece, you do not need a letter unless it is for a restricted medication
here is the exerpt from their customs site:
If you intend bringing small amounts of medication for personal use into Greece you may be required to provide documentation for customs clearance on entry which may include: A statutory Declaration from the patient, stating that the drugs are intended for personal use and that you are responsible for anything that may occur as a result of using the drugs. A doctor's prescription for the medication as well as a letter from the doctor stating the reason you are required to take the medication. Note that codeine is considered a narcotic in Greece and should be covered by a doctor's prescription. In situations where there is no doctor's prescription, which is likely if it is a long standing illness or for non-prescription medication, you need to provide a statutory declaration only. Note that the amount of medication being brought into the country must not exceed 2 bottles/boxes of each medication and up to five different types of medication.
would a repeat prescription be useful for this?
if you want, but you really don't need it
have a wonderful trip!
I hope that I provided you with excellent service ? :-)?
