Behind every prescription is a team

Your prescriber selects medications based on your health needs, but they may not always be aware of which options work best with your specific pharmacy benefit. That’s where we come in. Express Scripts® Pharmacy Benefit Services helps connect the dots to make sure you have access to medications that are appropriate, covered, and affordable under your plan.​

We make sure your care fits into your life.

Here’s how we fit in

We work behind the scenes to connect the people, benefits, and services that help you get the medications you need.
