You can get long-term, maintenance medications in one of two ways—through mail order or by going to any of Express Scripts’ retail partners. No matter which option you choose, your copay remains the same. You can still get two 30-day supplies of newly prescribed maintenance medications at any network pharmacy. After that, you can save money by ordering a 90-day supply through Express Scripts, delivered either by mail or to one of their retail partner locations. Be sure to ask for a 90-day prescription from your physician to qualify for the lower cost.
