Christopher Little and Alistair Boxall (VR, 25 January 2020, vol 186, p 97) called for a stop to the ‘blanket prophylactic use’ of antiparasitic drugs, and encouraged a return to strategic prescribing to minimise environmental exposure. Factors that might have brought about a change in prescribing practice are the emergence of pet health plans and client reminder services that aim for year-round comprehensive parasite protection, increased awareness of the lungworm Angiostrongylus vasorum, and an expansion in the choice of broad-spectrum parasiticide products.

Companion animal parasiticide products are unquestionably valuable for reducing the disease burden associated with parasites. Currently, assessment of the environmental effects of these products before marketing approval is limited and we need urgently to understand more about the risks to the environment from their overall use. In the meantime, it makes sense to stop unnecessary use of the drugs. But how can this be done?
