COMMENTS

This product is a classic oral paste dewormer for horses from CEVA with generic oxfendazole.

Oxfendazole is a veteran benzimidazole introduced in the 1970s (by WELLCOME) 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).

Oxfendazole has no residual effect, i.e. it kills the parasites after administration but does not protect against reinfestations. In year-round control programs the recommended treatment interval is usually 4 to 6 weeks.
