Current Animal Drug Shortages

Español

Sponsors and manufacturers provide most drug shortage information and FDA works closely with them to help prevent or reduce the impact of shortages.

FDA may disclose information that sponsors/manufacturers voluntarily submit to the Agency as permitted by applicable disclosure law, which includes restrictions on the release of confidential commercial information and trade secrets.  If FDA determines that a product is in shortage, the Agency generally intends to work with sponsors and manufacturers to confirm the accuracy and appropriateness of information regarding the shortage before posting publicly on FDA’s website.

Veterinarians sometimes use FDA-approved human drugs in their patients in an extra-label manner. Please see Human Drug Shortages.
