tapeworm treatment options, following the news that Equitape is to be withdrawn from sale in October 2018. In aturn of fortune for horse health, aspecial manufacturer dedicated to the veterinary industry has stepped up to fill this gap. A new praziquantel-only equine product will be available to vets from August 2018. Consultant vet to Westgate
E
Labs, Carolyn Cummins MVB PhD MRCVS commented “Retaining a species-targeted
treatment option is a fantastic outcome for sustainable worming practice and will go a long way in helping us to tackle the major welfare threat of wormer resistance. Evidence based control combining regular testing and targeted treatment is the best chance we have of protecting our horses from endemic disease caused by parasite infection both now and in the future.”
HORSE WORM TREATMENT PRESCRIBING OPTIONS WITH THE AVAILABILITY OF A PRAZIQUANTEL-ONLY WORMING PRODUCT
Where it has been confirmed that treatment for tapeworm is needed following a positive tapeworm test then the approach to other parasites (most usually redworm and roundworm) should also be considered by conducting a worm egg count. If treatment for just tapeworm
is indicated then a praziquantel only wormer would be one of the preferred choices of your vet. Alternatively, a double dose of pyrantel can be recommended for administration if;
• ascarids are also present (more likely in foals or yearlings)
or • the redworm population in question is known to not be resistant to pyrantel. Where treatment for redworm
is indicated at the same time as tapeworm treatment, then an ivermectin + praziquantel combination wormer would be the recommended selection through spring, summer and autumn. In winter when a proactive
treatment for the possibility of encysted redworm is advised then a moxidectin + praziquantel would be preferred treatment or alternatively a praziquantel only wormer followed two weeks later by a moxidectin only wormer or 5-day fenbendazole where there is no resistance known.
EVIDENCE BASED
CONTROL Regular testing should form the centre of any programme to determine whether or not a worming treatment is required to keep drug exposure to a minimum. Worm egg counts should be conducted every two- three months (with frequency depending on risk) and tapeworm tests performed every six months to monitor infection levels in healthy adult horses. Lester & Matthews (2013)

identified that: “Faecal egg counts can be used to identify the likely 15- 20% of horses that need worming to reduce worm egg shedding and
arlier this summer horse health experts raised concerns over the implications of
can reduce wormer use by up to 82%”. EquiSal Tapeworm test data shows that fewer than 27%of horses tested require treatment for tapeworm (Austin Davis Biologics) and Lightbody et al (2017) demonstrated that using EquiSal Tapeworm in a targeted worm control programme reduced the use of tapeworm wormers by 86%.
