The Ministry of Primary Industries (MPI) defines an ‘adverse event’ as: any observation in animals (or humans) that is unfavourable and unintended, and that occurs after the use of an agricultural compound or veterinary medicine (ACVM) product. This can include side effects, target animal safety issues, residue issues, lack of efficacy or alleged interaction with other products, and events that are recognised outcomes of product use and that may or may not be identified on the product label.

Bayer participates in the adverse event reporting program and has a legal obligation to investigate, record and report details of adverse events to the ACVM group (MPI).

If you are concerned that your animal has experienced an adverse event, seek veterinary advice from your usual veterinarian. There is some essential information required to investigate an adverse event including:

1. Reporter name and contact details

2. Patient information

3. Trade name of the product suspected to be involved

4. A brief description of clinical signs experienced and any other treatments given

This information and further details should be reported to the Pharmacovigilance Manager by any of the following methods:
