For how long?
Most drugs you have to have a new prescription every year and you have to go see a doctor to get it.
Generally bloodwork is involved.
For the good stuff, drugs with a resale value, it is often one month and a blood draw every three months.
My blood pressure meds are renewed every 3 months and I talk to the doc only over the phone with a home B P machine
my dtr is on two meds for her dystonia that she can only get a one month supply at a time....often the pharmacist has to get a new script and this after she’s been on these meds for almost a decade,
