What do I do if I am offered an unauthorised veterinary medicine?
You should recognise that a product that claims to treat and/or if administered modifies physiological functions by exerting a pharmacological, immunological or metabolic action but has no Marketing Authorisation is in breach of the Veterinary Medicines Regulations and can carry no claim of safety or efficacy. Possession or supply, or administration to animals of unauthorised medicines is illegal under the Veterinary Medicines Regulations. It may put your horse at undefined risk, and may also place you in breach of the Rules of Racing.
You should inform your veterinary surgeon if you are so approached, or the VMD.
