All prescriptions are valid for twelve months, but the medicine will be dispensed every 90 days (quarterly). You will be notified each time you are due for a quarterly refill. At this time the card on file will be charged and our partner pharmacy will ship your next quarterly supply of treatment directly to your door. Upon the expiry of your twelve-month prescription, you will be prompted to complete another short consultation with a prescribing physician who can provide a new prescription, allowing you to take advantage of another twelve months of XYON member benefits.
