General Information

Restricted Livestock Drugs and California Prescription Drugs

Certain antimicrobial restricted livestock drugs changed status on January 1, 2018 to require a prescription for purchase and use in California. CDFA has published final regulations clarifying new retailer requirements to sell restricted livestock drugs, including products that now require a prescription in California. Pursuant to the new regulations, these products are now defined as California prescription drugs. The adopted regulation text and final statement of reasons can be found at: /is/Regulations.

Please reference the documents below for more information about important changes to how these products can be sold. Additional resources will be posted as they become available.

For more information about medically important antimicrobial drugs, please visit the Antimicrobial Use and Stewardship website.
