Epocrates is a publisher of mobile device software applications, designed to provide information about drugs to doctors and other health care professionals. The Texas Medicaid formulary and Preferred Drug List are available on the Epocrates drug information system. The service is free and provides instant access to information through internet or on handheld device about the products on the Texas Medicaid formulary.

Once registered, users can utilize Epocrates Rx, the free drug reference with searchable brand, generic, and over-the-counter medicines. Users can select the “Texas Medicaid” formulary option to allow searches by drug name to determine preferred or non‐preferred products or products subject to clinical prior authorization criteria. Epocrates does not mirror the HHSC designations differentiated by dosage form. In these situations the designation is accompanied by an explanatory message.
