The TRICARE Formulary is a list of brand-name and generic drugs available through the TRICARE pharmacy benefit. Some drugs are covered but not preferred, and are categorized as Non-Formulary. These drugs have a higher copayment and generally are only available via home delivery.
You can use the TRICARE Formulary Search Tool to search for specific drugs and to see whether they are available through the TRICARE pharmacy benefit and if they are, what you will pay. The TRICARE Formulary Search Tool will also advise as to any quantity or day supply limitations associated with the drug in question.
