Virbac Razor Equine Wormer Paste is a broad-spectrum antiparasitic for horses, combining ivermectin and praziquantel in a single 30ml paste syringe. The dual-active formulation covers a wide range of internal parasites in one treatment, with each syringe dosed to treat two horses up to 600kg each.

The ivermectin and praziquantel combination targets large and small strongyles (including benzimidazole-resistant strains), ascarids, pinworms, hairworms, large-mouthed stomach worms, all three tapeworm species, and all three bot species. Arterial larval stages of Strongylus vulgaris are included in the spectrum. Safe for use in foals, pregnant mares, and breeding stallions.

The two-dose-per-syringe format makes it practical for properties managing multiple horses, reducing per-head treatment cost. The broad spectrum — tapeworm and bot coverage alongside strongyle control — reduces the need for separate treatments per worming rotation.
