Urgent safety updates for veterinary medicines

Urgent safety updates arising from pharmacovigilance data, including reported adverse events, for veterinary medicines authorised in the UK.

Reporting an adverse event

An adverse event is any observation in animals, whether or not considered to be product-related, that is unfavourable and unintended and that occurs after any use of a veterinary medicine, whether off-label or on-label use. This include events related to a suspected lack of expected efficacy according to approved labelling or noxious reactions in humans after being exposed to a veterinary medicine.

If anyone becomes aware of an adverse event involving a veterinary medicine they can report this either to the company, the Marketing Authorisation Holder (MAH), or directly to the VMD.

The MAH for a product can be found on the product leaflet or by searching for the product on the Product Information Database.

You can also report directly to the VMD using our online reporting form.

The VMD’s pharmacovigilance team continuously monitors all adverse event reports that are submitted to the VMD and reports submitted directly to the MAH.
