Horse Parasiticides

How to use the guide

This guide is intended to help you compare and choose parasiticide products for horses and donkeys. It contains all the products authorised for use in the UK. For full information on prescribing and using the products (including the specific authorised indications, doses, contraindications, adverse effects, interactions, handling etc), consult the product’s summary of product characteristics (SPC, available for each product on the Veterinary Medicines Directorate website). 

You can search using any or all of the following categories: species, active ingredient, brand, drug class, formulation and parasite/disease. For parasite/disease and active ingredient, it is possible to select several terms by clicking on the adjacent plus sign; you can deselect a term by clicking the adjacent minus sign. Each category has a blank area at the top of the drop-down menu, which you should select if you don’t want to use a particular category in your search. There are further notes on the search results (about use in pregnancy and supply category) underneath the search engine.

Parasite/disease: coverage is according to the authorised indications of the product. In order to keep this resource simple, we have referred to indications generally and using common names: large strongyles (e.g. Strongylus vulgaris), small strongyles (e.g. cyathostomins), pinworm (e.g. Oxyuris equi), large roundworm (Parascaris spp.), intestinal threadworm (Strongyloides westeri), stomachworm (Trichostrongylus axei), large-mouth stomachworm (Habronema spp.), lungworm (Dictyocaulus arnfieldi), neck threadworm (Onchocerca spp.), common tapeworm (Anoplocephala perfoliata). Check the relevant product SPC for specific indications. We have also indicated which products are authorised as having an effect against larval forms of S. vulgaris and pinworm, and against encysted cyathostomin larvae.
