Epocrates

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 about the Texas Medicaid formulary through the internet or a handheld device.

Once registered, users can select the “Texas Medicaid” formulary option, allowing searches by drug name to determine which products are preferred, non‐preferred, or subject to clinical prior authorization criteria. Epocrates does not mirror the HHSC designations differentiated by dosage form. In these situations, Epocrates accompanies the designation with an explanatory message.
