Presentation

A white to greyish white granules for oral administration. Each g of Zerofen 22% Equine Granules contains 0.22 g of Fenbendazole.

Uses

Zerofen 22% is a broad-spectrum anthelmintic for the treatment of horses and other equines infected with benzimidazole susceptible immature and mature stages of nematodes of the gastro-intestinal tract including large redworms (Strongylus vulgaris, Strongylus edentatus) and migrating large redworms, small redworms and encysted mucosal larvae, Ascarids, Oxyuris and Strongyloides species. Zerofen also has an ovicidal effect on nematode eggs.

Dosage and administration

For oral administration only. Granules should be sprinkled onto concentrate or grain feeds and the full daily dosage given as one administration.

The dose rate is 7.5 mg fenbendazole/kg bodyweight, equivalent to 10.2 g granules per 300 kg body weight or 2 level measuring scoops.

Assess bodyweight accurately before calculating the dosage. Treatment should be repeated when natural re-infestation with worms occurs (approximately every 6 to 8 weeks).

Dosage Table:
Foals and ponies up to 300 kg bodyweight	2 level scoops
Thoroughbreds and other breeds of horses up to 600 kg bodyweight	4 level scoops
Heavy hunters, heavy draught horses	6 level scoops
Donkeys	1 level scoop

For the treatment of encysted mucosal stages of Cyathostomes (small strongyles) the dose rate is 30 mg/kg, which is equivalent to 40.5 g granules per 300 kg body weight or 8 level measuring scoops.

For the treatment of migrating stages of Strongylus vulgaris and tissue stages of Strongylus endentatus the dose rate is 60 mg/kg, which is equivalent to 81 g granules per 300 kg body weight or 16 level measuring scoops.

Increased dosing for specific infections

For the control of encysted mucosal stages of small strongyles and migrating larval stages of large strongyles administer 7.5 mg fenbendazole/kg bodyweight daily for 5 days which is equivalent to 10.2 g Zerofen granules per 300 kg body weight or 2 level measuring scoops, daily for 5 days. Ideally dosage at this dose rate should be carried out at once a year between the end of October and December. All new arrivals should be treated at this rate whatever the time of year.

For the treatment of diarrhoea caused by Strongyloides westeri in 2 to 3 week old suckling foals the dose-rate is 50 mg fenbendazole/kg bodyweight, which is equivalent to 10.2 g Zerofen granules per 44 kg body weight or 2 level measuring scoops.

Pregnant mares and young foals may be safely treated with fenbendazole at therapeutic dosage levels.
