Veterinary medicinal products containing toltrazuril to be administered orally to chickens

Current status
European Commission final decision


On 14 July 2022, the European Medicines Agency (the Agency) completed a review of the safety of oral veterinary medicines containing toltrazuril for use in chickens. The Agency’s Committee for Veterinary Medicinal Products (CVMP) concluded that the benefits of these veterinary medicines continue to outweigh their risks but that risk mitigation measures should be taken to assure consumer safety, including the amendment of the restriction period before the onset of lay. The restriction period is the time between the administration of a medicine and the start of the laying period in which chickens must not be treated.
