Report a problem with an animal medicine

You can report:

  • a reaction in an animal or a person
  • times when a medicine has not worked

You can report a problem by:

  • telling your vet
  • using the contact details on the leaflet that came with the medicine - if the product is an approved animal medicine (if you do not have the leaflet, search for the company also known as the MA holder)
  • contacting the Veterinary Medicines Directorate (VMD) - if an animal has been given a human medicine or a medicine that is not approved for use in animals

If you report a problem to the company, they must share that report with the VMD within 30 days.

The VMD will use reports to check if medicines continue to be safe and work as expected.

Contact the VMD

To report a problem if an animal was given human medicine or medicine that is not approved for use in animals, email adverse.events@vmd.gov.uk to request a form.

You can also contact the VMD if you have questions about how to report a problem.
