Off Licence Medications

Drugs and medicines which may be used in the veterinary treatment of animals are controlled by a government body called the Veterinary Medicines Directorate (VMD).

For a variety of reasons (including health and safety) veterinary surgeons are required by law to use, wherever possible, and in each species, only those drugs that have undergone a rigorous testing and licensing procedure in that species.

This means that, where such a licensed drug exists, we have researched data on dose rates, its therapeutic benefits and also possible side effects. The problem is that it can be extremely expensive for a drug company to fulfil all the regulatory requirements for all drugs for all species.

This means that a large number of drugs and medicines (veterinary and human), many of which we have been using for years without any known problems, now fall outside the list of authorised products. It also means that many drugs which are licensed in one species (i.e. dogs) are not licensed in another (i.e. cats). This is particularly true when it comes to the use of medicines in small pets like rabbits, guinea pigs and hamsters etc.

The list of commonly used drugs which are not authorised includes some surprisingly common and essential drugs including Adrenaline, Atropine, Morphine and certain antibiotics such as Metronidazole. A large number of human medicines with a known track record of quality and long standing use in veterinary medicine also fall outside authorisation. The current legislation also requires that veterinary surgeons are obliged to use a branded (licensed product) whereas non branded medicines (albeit the same active ingredient), often called “generic”, are off licence.

In recognition of these problems, where a suitable authorised medicine is not available, the VMD does allow veterinary surgeons to use other drugs. The drugs they may use are grouped in a descending order of suitability based on how close they are to authorised alternative. The order of suitability is known as the “Cascade” system. Veterinary Surgeons must choose medicines as near to the top of the cascade as possible, but can choose from lower levels if none is available from the level above.
