Documents
Details
Marketing Authorisation Holders (MAHs) have a legal obligation to record any information which they receive about adverse events involving their veterinary medicinal products.
These can occur after use in accordance with the advice on the label, following off-label use or if there is suspected lack of efficacy (the product has not worked) when used in accordance with the label. Reporting also relates to humans following exposure to a veterinary medicine or a treated animal.
MAHs must report any animal adverse events involving death, permanent disability, life threatening illness or congenital abnormality, and all human reactions, to the relevant competent authority. In the UK this is the Veterinary Medicines Directorate.
The scope of reporting includes incidents arising from exposure to a veterinary medicine present in the environment, and issues concerning the validity of withdrawal periods.
A scientific evaluation of the risk-benefit balance of the veterinary medicine is an important aspect of reporting.
