Pharmacovigilance & Reporting Adverse Events


If you suspect an adverse event either in animals or humans that may be associated with the use of a Norbrook  product or if you believe there is a a product quality issue with a Norbrook product, please report the details immediately by completing the form below.

  • What is an adverse event?

    An adverse event is a report of a harmful and unintended outcome which is due to exposure to a veterinary medicine administered to an animal. In other words it is any harmful or unexpected side effect to a veterinary medicine. Adverse reactions can occur in animals treated with veterinary medicines, or people who are exposed to veterinary medicines or treated animals. Adverse events also include instances where a veterinary medicine does not work as intended (lack of efficacy), adverse environmental effects and problems with residues of veterinary medicines in human food (milk and meat).

  • What happens to reports when they are received?

    Following receipt of the report, a Norbrook representative will be in touch to discuss the case. Every adverse event report received by Norbrook is recorded and investigated, before being reported to the government agency of the country in which the event occurred.

  • How can I report an adverse event?

    If you consider that you or your animal(s) have reacted badly to a veterinary medicine and you need veterinary or medical advice, you should contact your veterinary surgeon or doctor who will be able to discuss the reaction with you, initiate any treatment required (if possible take the medicine container, or label for a large pack, or package leaflet with you).
