ICSA Animal Health and Welfare chair John Barron has said the delay in introducing prescription-only rules for antiparasitic medicines until 1 December, 2025 must not be wasted.

He is calling on Minister Heydon to use the extra time to completely rethink how the regulation is being rolled out.

“Tweaking the timeline isn’t enough – the whole approach needs a serious rethink,” he said.

Under the planned rules, routine antiparasitic treatments like wormers and fluke doses will require a vet prescription, issued through the new National Veterinary Prescription System (NVPS). Farmers will no longer be able to buy these products over the counter from their local co-op or licensed merchant without first going through a vet.

Mr. Barron said the Department must use this extra time to properly engage with all stakeholders – not just vets – and come back with a solution that works in practice, not just on paper.

“This is a chance to get it right. That means keeping licensed merchants in the supply chain and finding a system that actually works for everyone. This can’t just be a delay to push through the same flawed plan. The Minister must listen and go back to the table. We need a system that works for farmers, vets, and merchants alike,” Mr. Barron added.
