"On most meds they can fill up to a year's worth without seeing you."
Even in the US it is not always so simple. Some states will only allow ONE fill of an out-of-state rx, and even if there are more refills on the rx, they get cancelled. Some pharmacies, doctors, and insurers, will only allow a 30 day fill, tops a 90-day fill. It is not always logical or simple.
If you are a US visitor in Canada
, last time I checked you could see a Canadian physician, pay about $50US for a consultation, and if you gave them your medical history
rxes, they would write you a matching set that you could use in Canada
, at least once. That's how a lot of Americans bought drugs in Canada at greatly reduced rates. "Canada" of course has varying rules in the different provinces--so this may not be uniform either.
Les, your best bet would be to spend some time on the phone/email with your doctor, your insurer's pharmacy, and a pharmacy in each destination
you are thinking of, to see if they all come up with the same answers. If you have a home pharmacy they can always send you drugs via postal express--assuming they will do so, ignoring the costs, and assuming you're in one place long enough to fetch the package.
Drugs can always be had, the rest is "just" logistics and money
