The question

To ask the Secretary of State for Environment, Food and Rural Affairs, what assessment her Department has made of the safety of the veterinary medicines Librela and Solensia.

Answered by Dame Angela Eagle

All veterinary medicines, including Librela and Solensia, are subject to rigorous scientific assessment before approval to ensure their benefits outweigh risks when used as authorised. Once approved, they are continually monitored through pharmacovigilance to ensure this remains the case.

Available data show that reported adverse events are uncommon, occurring in approximately 1–10 animals per 1,000 treated. Reports include cases involving use with other medicines, off‑label use, or events later attributed to other causes.

Following in‑depth review of all available evidence, including for Librela, the Department is satisfied that the overall benefits of these products continue to outweigh the risks for the vast majority of animals. As with all medicines, risks exist, and monitoring will continue, with further action taken if new evidence warrants it.
