In 2019, the Texas State Legislature passed House Bill 2536 relating to drug cost transparency. It requires pharmaceutical drug manufacturers to report certain cost information on U.S. Food and Drug Administration-approved drugs sold in or into Texas.

The 2020 wholesale acquisition cost (WAC) cost information on January 1, 2020 for all United States Food and Drug Administration-approved prescription drugs sold in or into Texas from pharmaceutical drug manufacturers is now available to view on the Data link.

The drug cost transparency information is updated regularly and is made available to comply with Chapter 441.
