Companies must report supply problems to the Veterinary Medicines Directorate when product shortages are identified. A shortage occurs when supply of a veterinary medicine does not meet national demand.

Information on product shortages where there is no known alternative product is published here. In such instances, vets may prescribe using the cascade. Vets are reminded that it is their responsibility to apply use of the cascade appropriately based on clinical need.

More information can be found on The Cascade: Prescribing unauthorised medicines page.

For non-UK products vets must apply for a certificate to import a Veterinary Medicine into the UK.

For information on manufacturers of extemporaneous products, please read the ManSA Register

  Vaccines for immunisation against equine influenza and tetanus

  The VMD have been informed that there is now returned supply of UK authorised equine flu and tetanus vaccines.

  The VMD will no longer accept applications to import alternative products, including Vetera 2XP licensed in the USA.

  Vaccine for immunisation against ringworm

  Following the granting of a marketing authorisation, the VMD have been informed that there is availability of Trichovec, Lyophilisate and Solvent for Suspension for Injection for Cattle (Vm 51609/3000 and 51609/5000).

  Therefore the VMD will no longer issue import certificates for ‘Trichoben’ as authorised in the Czech Republic and Netherlands.

  Products containing acepromazine for anaesthetic premedication, tranquilisation and sedation in horses

  Following the granting of a marketing authorisation the VMD have been informed that there is availability of a 10mg/ml acepromazine solution for injection:

  • AceSedate 10mg/ml solution for injection for horses Vm: 25296/4008

  Therefore the VMD will no longer issue import certificates for alternative acepromazine products, including:

  • Calmivet solution for injection (5mg/ml), licensed in France
  • Vetranquiol 1% solution for injection (10mg/ml), licensed in Germany and Netherlands

  This will take effect immediately.

  Existing certificates will remain valid until their date of expiry, however veterinary surgeons are reminded to apply the Cascade responsibly and use UK authorised product where available.

  2mg/ml presentations are also available. Information on authorised acepromazine-containing products is available on the VMD’s Product Information Database.
