For medication you need on an ongoing basis — called maintenance medications — you have two ways to get up to a 90-day supply.

You can conveniently fill these prescriptions either through the Express Scripts Pharmacy (home delivery) OR from any Walgreens pharmacy. Examples of conditions commonly requiring ongoing medication include hypertension (high blood pressure), high cholesterol, asthma, heart disease, and diabetes.

You will be able to fill your maintenance medication at your local pharmacy once with up to two refills. After that, you will be responsible for the full cost of the medication if you don’t use the mail order or Smart90 program through Walgreens.
