Fenbendazole is a broad-spectrum anthelmintic belonging to the benzimidazoles, effective against roundworms and, depending on the dose, also against some tapeworms (e.g. Moniezia spp) as well. It is ineffective against flukes (e.g. Fasciola hepatica adults) at the usual therapeutic dose. It is completely ineffective against external parasites. Oral administration is the rule. It is used massively in all kinds of livestock (mainly in drenches and feed additives), and abundantly in pets (often in tablets, pills, etc. or oral suspensions) and horses (mostly in oral pastes & gels). There are hundreds of generic brands worldwide, also in mixtures with other anthelmintics.
Fenbendazole is not used against agricultural or household pests. Unfortunately, resistance of gastrointestinal roundworms to all benzimidazoles in sheep, goats, cattle and horses is a major problem in numerous countries. Not so yet in pets, swine or poultry. In ruminants, a 50% reduction of the diet 36 prior and 8 hours after treatment slows down the passage through the stomach, which increases the bioavailability of benzimidazoles and their metabolites and consequently its efficacy against gastrointestinal parasites.
In carnivores (incl. dogs and cats) delivery with the food increases the bioavailability of all benzimidazoles resulting in a better efficacy. All benzimidazoles have almost no residual effect, i.e. they kill the parasites during a few hours after treatment but offer no significant protection against re-infestation.
