If you take a medicine to treat a long-term condition (one that lasts 3 months or longer), then your prescription plan might use certain rules that affect the price of your medicine and the way you get it. A “courtesy fill” is the number of fills and refills you can order, before these rules fully take effect.\r\rThese rules include factors such as the medicine type, form, amount you get, what pharmacy or pharmacy network you use, and others. After you’ve used your “courtesy fills” limit, you’ll need to follow your plan’s rules for getting your medicine in order to avoid paying a higher price for it.
