Veterinary medicines legislation

The legal text underpinning the regulation of manufacture, authorisation, marketing, distribution, use and post-authorisation surveillance of veterinary medicines and medicated feed.

There are several pieces of legislation which set out the controls on veterinary medicines and medicated feed and form the basis for their regulation in the UK. Under the Windsor Framework, separate legislation on veterinary medicines applies in Great Britain and in Northern Ireland.

For the text of the relevant legislation go to legislation.gov.uk.

Legislation in GB

Veterinary medicines and medicated feed

The Veterinary Medicines Regulations 2013 (S.I. 2013/2033; VMR) set out the legislative regime for veterinary medicines and medicated feed and came into force on 1 October 2013. The VMR as originally made extended to the UK. However, under the Windsor Framework, EU law on veterinary medicines and medicated feed applies in respect of Northern Ireland. Accordingly, changes were made to the VMR following EU Exit which applied in GB but not in NI, and vice versa.

The VMR (as amended) set out the controls on the manufacture, authorisation, possession, distribution, use and post-authorisation surveillance of veterinary medicines and medicated feed. The VMR are periodically amended after consultation with interested stakeholders to ensure that they are up-to-date and fit for purpose.

The latest amendments for GB were made by the Veterinary Medicines (Amendment, etc.) Regulations 2024.
