I'm in the step therapy program. Why couldn't I fill my prescription at the pharmacy?

The first time you submit a prescription that isn’t for a front-line drug, your pharmacist should inform you that with step therapy you need to first try a front-line drug if you’d rather not pay full price for your prescription drug.

To receive a front-line drug:

  • Ask your pharmacist to call your doctor and request a new prescription.


  • Contact your doctor to get a new prescription.

Only your doctor can change your current prescription to a first-step drug covered by your program.


If you have more questions, you can log in and go to to watch informative videos or call the Express Scripts Pharmacy at the number on your ID card. (This FAQ answer provided by ExpressScripts.)
