Nitroxynil
This is an injectable product and useful for quarantine treatments. This product will kill fluke from 7 weeks of age and over (and is also effective against Haemonchus contortus or barber’s pole worm). Resistance to the product has not been confirmed in the UK so it is very likely to be effective.
This product could be used as a quarantine treatment in conjunction with triclabendazole – give the triclabendazole first when the new stock arrives, and the nitroxynil second.
A gold-standard protocol could include two treatments with this product 7-8 weeks apart, followed by a 3-week wait, before joining the main flock.
Note: Although unlikely in recently purchased sheep – this product may be unsuitable if sheep are already showing signs of illness due to fluke. With all drugs, dosage should be determined accurately, but this is particularly important with this product.
