This is a list of the most commonly prescribed drugs. It represents an abbreviated version of the drug list that is at the core of CASEBP's prescription plan. This list is not all-inclusive and does not guarantee coverage. In additional to using this list, you are encouraged to ask your doctor to prescribe generic drugs whenever appropriate. 

This list also shows the excluded medications not covered on the Express Scripts National Preferred Formulary beginning January 1, 2024. In most cases, if you fill a prescription for one of these drugs, you will pay the full retail price. It is encouraged to discuss with your provider the consideration of writing a new prescription for one of the preferred alternatives.

Is your medicine cabinet full of expired drugs or medications you no longer use? Your medicine is for you. What’s safe for you might be harmful for someone else. The best way to dispose of your expired, unwanted, or unused medicines is through a drug take back program — or you can do it at home.
