Indications for use
For the treatment and control of headflies, and treatment of ticks and biting lice. For the prevention and treatment of blowfly strike.
Not to be used in lambs less than one week old.
For the prevention of blowfly strike; do not administer to animals of less than 12.5 kg bodyweight.
Avoid treating very young lambs if the weather is unseasonably hot.
Do not use in the case of hypersensitivity to the active substance or to any of the excipients.
Special warnings for target species
Frequent and repeated use of antiparasiticides from the same class may increase the risk of development to resistance.
Special precautions for use in animals
Care must be taken not to apply the product right to the lamb’s tail, as a ewe recognises a young lamb partly by the smell of the tail area.
Blowflies are attracted by dirty, damp wool or open wounds. The more common site for fly strike is the rump due to soiling caused by diarrhoea and urine staining. The efficacy of the product is reduced in the presence of soiled or dirty wool. Therefore, sheep must be dagged (crutched) regularly and appropriate worm control measures employed.
Take care not to apply product in the sheep’s eyes. This precaution should be observed particularly when treating breeds with little wool on their heads.
Full operating and maintenance instructions, including details on the use of nozzles are supplied with each applicator gun. Please read carefully before use. Maintain applicator gun carefully to ensure accurate dosage.
For external use only.
Special precautions to be taken by the person administering the veterinary medicinal product to animals
This product may also cause hypersensitivity reactions.
Avoid skin and/or eye contact.
Avoid children from getting access to the product or treated animals.
Use in a well-ventilated area and avoid inhaling the vapour.
Wear eye protection, protective clothing, rubber gloves and boots when applying the product and handling the animal until the product has dried.
Wear a disposable face-mask when applying as a fan-spray for the prevention of blowfly-strike.
Make sure when attaching the recommended applicator gun onto the container that the coiled retainer is secured onto the cap and the applicator.
Wash splashes from skin and eyes immediately with plenty of clean water.
If irritation persists seek medical advice immediately and show the package leaflet to the physician.
Remove contaminated clothing immediately and wash exposed skin with plenty of clean water.
Do not eat, drink or smoke whilst using the product. Wash hands immediately after use.
In case of accidental ingestion or mouth contact, immediately rinse the mouth with plenty of water and seek medical advice.
Other precautions
Cypermethrin is extremely toxic to aquatic and dung organisms As a precautionary measure sheep must be kept away from watercourses for at least 12 hours following treatment (see section 5.3, ‘Environmental properties’). Given the risks to the environment the use of the product should be limited to one treatment per year per pasture. Long term effects on dung insects caused by continuous or repeated use of pyrethroid ectoparasiticides cannot be excluded. Therefore repeated treatment of animals on the same pasture with a pyrethroid-containing product within a season should only be given in the absence of alternative treatments or approaches to maintain animal/flock health, as advised by a veterinarian
Adverse reactions
None known.
Use during pregnancy or lactation
Can be used during pregnancy. Pregnant ewes must be handled with care. See section 'Withdrawal Periods'.
The product must be applied only with the recommended applicator gun, as the product may have a detrimental effect on certain components of conventional dosing guns.
Amounts to be administered and administration route
To ensure administration of a correct dose, body weight should be determined as accurately as possible; accuracy of the dosing device should be checked. On completion of each treatment cycle of the product and before the dosing gun is stored, immediately expel any remaining product in the dosing gun.
