Risk of resistance? YES
- Small strongyles (cyathostomes). Resistance of small strongyles to benzimidazoles is widespread and frequent e.g. in the USA, UK and Europe, Argentina, Chile, Uruguay, etc.
- Parascaris equorum: Cases of tolerance to benzimidazoles have been also reported (e.g. in the USA). Resistance to macrocyclic lactones (e.g. ivermectin, moxidectin) has been reported in the USA, UK and Australia.
This means that if this product does not achieve the expected efficacy against the mentioned parasites, it may be due to resistance and not to incorrect use, which is usually the most frequent cause of product failure.
- Imidazothiazoles, mainly levamisole. Not approved for use in horses in many countries.
- Macrocyclic lactones: mainly ivermectin, moxidectin. But tolerance or resistance to these compounds have also been reported in Europe (e.g. in the UK, Germany, Italy), the USA, and Brazil.
- Tetrahydropyrimidines, mainly pyrantel (limited spectrum of activity), but resistance cases have also been reported (e.g. Australia, USA, Brazil, Japan).

This product is a classic feed additive dewormer for horses from ELANCO with generic mebendazole.
Mebendazole is a veteran benzimidazole introduced in the 1970s (by JANSSEN) that is moderately used in horses and pets, but rather scarcely in ruminants. It is also used in human medicines. 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).
