WSD Closantel 1L

WSD Closantel is a narrow spectrum treatment for internal parasites of sheep and lambs with sustained action against re-infestation by Haemonchus contortus (barbers pole worm), and activity against Fasciola hepatica (liver fluke).

Type of Preparation:  WSD Closantel  is a clear solution for oral use as a drench containing 37.5g/L closantel – a member of the salicylanilide and substituted phenol group of compounds.

Indications:
Sheep and Lambs: Haemonchus contortus (barber's pole worm), Fasciola hepatica (liver fluke) from 6 weeks, and Oestrus ovis (nasal bot). Closantel provides sustained protection against the re-infestation by both mature and immature stages of barber's pole worm in sheep for 4 weeks after dosing. Closantel controls both mature and immature stages of liver fluke as well as all stages of nasal bots.

Milking Sheep: Do NOT use in sheep producing milk for human consumption

Dosage:
Always refer to the label. Separate into different weight classes if there is a large variation in age and weight.
Dose at the rate of 1mL per 5kg body weight.

Advice On Use:
• WSD Closantel  is particularly useful if administered in spring before the rise in Haemonchus parasites in the sheep or survival of larvae on pastures.
• Administration in spring is also useful in removing residual liver fluke infestations, and managing the contamination and early pickup of the liver fluke in affected areas. This provides a useful alternative to WSD triclabendazole products.
• When treating an outbreak of haemonchosis (barbers pole infestation), consideration should be given to using an alternative drench from the WSD range, particularly WSD LEVAMISOLE or WSD COMBINATION.
• WSD Closantel  is particularly effective when combined with management strategies to control haemonchosis including rotation and spelling of paddocks.
• Closantel is NOT effective against the other major gastrointestinal worm parasites.
• Resistance to Closantel is widespread among barbers pole worm (Haemonchus) in some sheep-raising districts.
• The repeated use of any drench is likely to result in the emergence of resistance and therefore, regular testing for efficacy is recommended if Closantel is used.
• The emergence of resistance on an individual farm is likely to result in the failure of Closantel to provide extended protection against re-infestation by Haemonchus.
