HORSE FIRST. EVERY TIME. EVERY SEASON.

A tailored, test-based parasite control programme can help keep your horse in peak condition

Best-practice approach is to plan a test-based programme, the interval of testing based on a horse’s relative parasite risk profile as Low, Medium or High for disease caused by worm burdens. Every horse’s parasite risk is unique and you can find out how a tailored, test-based parasite control programme and good results in the arena depend on much more than just training.

VMD adverse events reporting suspended

Overview and interim measures

The Veterinary Medicines Directorate (VMD) has paused independent reporting of adverse events by vets and SQPs, meaning these now need to be submitted via pharmaceutical companies. An adverse event is a reaction to veterinary products, including wormers. With concerns that issues might go unreported or downplayed as a result and delay critical safety signals, we've put together some more info and guidance.
