This product is a classic oral paste dewormer for horses from JUROX with with generic oxfendazole.
Oxfendazole is a veteran benzimidazole introduced in the 1970s (by WELLCOME, SYNTEX) that is moderately used in livestock and horses, rather scarcely in pets. It is a broad-spectrum anthelmintic effective against roundworms in the gut and the lungs, but not against those in the skin. It is also ineffective against gastric bots (Gasterophilus spp) or whatever external parasites. At the recommended dose it is also ineffective against horse tapeworms (Anoplocephala spp). It is moderately used in livestock, scarcely in horses and pets. It is not used in agriculture.
