The British Veterinary Association (BVA) is calling for the Veterinary Medicines Directorate (VMD) to consider the reclassification of medications on the General Sales List (GSL).
BVA published its first policy position on the use of parasiticides for dogs and cats in 2021 and the policy was updated in 2025 to reflect new research. The association has a joint policy position with the British Small Animal Veterinary Association (BSAVA) and the British Veterinary Zoological Society (BVZS).
Dr Gwen Rees, junior vice president at the BVA, said: “For our cats and dogs policy, we are actively calling for the VMD to consider the reclassification of GSL products. We’d like to see more oversight in the prescribing for cats and dogs, so that GSL medicines aren’t available without any advice given on responsible use.
“We know that for some of those products that are GSL, there is increasing evidence that they’re not harm-free for the environment.”
Bryan Lovegrove, AHDA secretary general, said he would work with the industry to raise the issue of responsible parasiticide use, and information to owners, however, he said the elephant in the room is supermarket sales of GSL products.
He asked: “How can you be encouraging prescribers to give out more information when owners can buy their GSL treatments with their bread and milk in supermarkets?
“I would support the reclassification of GSL products to POM-VPS.”
AMTRA chief executive Stephen Dawson added: “Reclassification of product category is a matter for the VMD.
“However, SQPs stand ready and are well placed to provide advice at the time of supply ensuring any products are supplied and used responsibly. Their expertise supports animal health, public and environmental safety, and appropriate disposal practices.”
OvertheCounter understands that the VMD is undertaking an evidence-based review of the distribution categories for companion animal parasiticides.
VMD explained that this review is part of its commitment to pharmaceuticals in the environment roadmap and reflects its role in ensuring medicines regulation balances animal health, public health and environmental protection.
“We’re committed to a transparent approach,” VMD said. “We’ll undertake a consultative process to ensure all evidence and stakeholder perspectives are clearly considered.”
As OvertheCounter went to press, Cardiff University’s Water Research Institute reported that chemicals used in spot-on pet flea treatments are widespread in rivers across Wales and are harming wildlife.
Ruth Jones MP for Newport West and Islwyn said it was “deeply worrying” that spot-on flea treatments are polluting waterways to such a degree.
“It isn’t a concern most pet owners would even consider when applying treatment,” Mrs Jones said.
“We should consider flea treatments only being made available via trained animal advisors so owners are better informed.”
OvertheCounter understands the VMD will launch a government-led national stewardship campaign this spring to raise awareness around flea and tick spot-on products and impacts on the environment.
