Following a joint workshop, SCOPS is delighted to have worked with Zoetis Animal Health to release updated advice on the use of moxidectin, and particularly the 2% injectable formulation.
The work with Zoetis was borne out of concern by both parties about reports of potential over-use, in particular as a treatment for ewes at lambing, coupled with an increase in the prevalence of moxidectin resistance in the UK.
Speaking on behalf of SCOPS, Lesley Stubbings says: “Constructive discussions between Zoetis and SCOPS agreed that the priority must be to preserve moxidectin both as an anthelmintic for worms and a treatment for sheep scab. In order to do this, the sheep industry must prescribe moxidectin responsibly, by applying the SCOPS principles.
“In practice, this means sheep farmers working with whoever prescribes their anthelmintic, be it their vet or SQP, to avoid over and/or unnecessary use of moxidectin, ensuring the treatment is always given at the right dose rate and administered correctly and allowing some worms to remain unexposed to the treatment.”
Prescribers are therefore reminded of the following SCOPS principles:-
Ms Stubbings continues: “SCOPS is also very pleased to have agreed with Zoetis that further work is required in this area – specifically assessment of the risk posed by the passing of moxidectin from lactating ewes to their lambs via milk – and also the possible role of moxidectin 2% in slowing the development of anthemintic resistance to other molecules. Both of these are very important and we hope both areas of work can be progressed positively.”
