TRICARE Formulary Search Tool

Use the TRICARE Formulary Search Tool to look-up your drug. A search can tell you:

  • Formulary status (generic drug, brand-name drug, non-formulary drug, non-covered drug)
  • Where the prescription can be filled
  • Copayments and limitations, such as prior authorization
  • Coverage review requirements and forms
  • Alternative medications, including costs

To start your search, you’ll need to put in the brand name or generic name of the drug and then select the strength prescribed, as well as your gender and age.
