AdverseReactions
Thankfully, harmful, unexpectedside-effects to animal medicines are extremely common. Before any animal medicine is allowed ontothe UK market it has, by law, to satisfy very strict criteria on its quality,its effectiveness and its safety.However, once an animal medicine is in use, it is vital to know if anyanimals or people suffer unexpected problems following use or exposure to theproduct under field conditions.
Very occasionally animals may show somesmall mild reaction to a medicine - just as you may feel drowsy after certaincommon medications. But, if your animalis unwell after treatment with an animal medicine or if you are at all worried,contact your vet. This is just common-sense, whether or not your animal hasreceived medication, and it is more that likely that the illness is totallyunrelated to the medicine.
The Veterinary Medicines Directorate (VMD),which administers the licensing system, runs a scheme to monitor reports of anyreactions in animals and people following the use of animal medicines, calledthe Suspected Adverse Reaction Surveillance Scheme.
