Be Prepared: Transitioning Certain OTC Antimicrobial Products to Rx June 2023

FDA published Guidance for Industry (GFI) #263 in June 2021 which outlined a plan for transitioning certain over-the-counter (OTC) antimicrobial products for animals to prescription (Rx) status. As outlined in FDA's Guidance for Industry (GFI) #263, FDA expects approved animal drug products containing medically important antimicrobials that are currently available as OTC products to transition to Rx status beginning in June 2023. To help prepare for this transition, FDA Center for Veterinary Medicine (CVM) is conducting outreach to increase awareness about this expected change.

FDA CVM has developed written materials with information on products/indications that will be transitioning as part of GFI 263 and information on how interested animal owners can locate a vet. Also linked below are a brochure and poster which detail the importance of veterinary involvement as products transition to Rx.
