The Irish Equine Veterinary Association has issued an official statement regarding recent advice from some suppliers encouraging horse owners to “stock up” on wormers ahead of the December 2025 regulation change.
IEVA does not support this practice.
Unsupervised or unnecessary use of antiparasitic products contributes to resistance, jeopardises equine welfare, and threatens the long-term effectiveness of these essential medicines.
From December 2025, antiparasitic treatments will require veterinary oversight. Wormers should only be used when there is a clinical indication, supported by diagnostic evidence such as faecal egg counts.
Responsible, evidence-based parasite control protects horses today and preserves vital treatments for the future.
