On lambs: For the treatment and prevention of infestations by ticks Ixodes ricinus and by lice Bovicola ovis.
Contra-indications
Do not use on convalescent or sick animals.
Do not use in cases of known hypersensitivity to the active substance or any of the excipients.
Extra-label use of the product in the non-target species dogs and cats can lead to toxic neurological signs (ataxia, convulsions, tremors), digestive signs (hypersalivation, vomiting) and may be fatal.
Special warnings for each target species
Do not apply on or near the animal’s eyes and mucous membranes.
To avoid resistance, the product should only be used if the susceptibility of the local fly population to the active substance is assured. If clinical signs do not resolve following treatment, the diagnosis should be revised.
Cases of resistance to deltamethrin have been reported in stinging and nuisance flies in cattle and lice in sheep.
In countries with recognized resistance to deltamethrin the use of the product should ideally be based on results of susceptibility testing. Please, ask your veterinarian for further information.
The product will reduce the number of flies resting directly on the animal but it is not expected to eliminate all flies on a farm. The strategic use of the product should, therefore, be based on local and regional epidemiological information about susceptibility of parasites, and used in association with other pest management methods.
Care should be taken to avoid the following practices because they increase the risk of development of resistance and could ultimately result in ineffective therapy:
-too frequent and repeated use of ectoparasiticides from the same class over an extended period of time;
-underdosing which may be due to underestimation of bodyweight, misadministration of the product, or lack of calibration of the dosing device.
Special precautions for use
Special precautions for use in animals
The product is for external use only.
Avoid contact with eyes and mucous membranes as Deltamethrin is an irritant.
Care should be taken to prevent licking of the product. Avoid use of the product during extremely hot weather and ensure animals have adequate access to water.
The product should only be administered onto undamaged skin as toxicity is possible due to absorption from major skin lesions. However, signs of local irritation may occur after treatment as skin may be already affected by infestation.
Special precautions to be taken by the person administering the veterinary medicinal product to animals
Persons with known hypersensitivity to the product or one of its components should avoid contact with the veterinary medicinal product.
Wear protective clothing including waterproof apron and boots and impervious gloves when either applying the product or handling recently treated animals.
Remove heavily contaminated clothing immediately and wash before re-use.
Wash splashes from skin immediately with soap and plenty of water.
Wash hands and exposed skin after handling this product and before meals.
In case of contact with eyes, rinse immediately with plenty of clean, running water and seek medical advice.
In case of accidental ingestion, wash out mouth immediately with plenty of water, seek medical advice and show the package leaflet to the physician.
Do not smoke, drink or eat while handling the product.
This product contains deltamethrin which may produce tingling, itchiness and blotchy redness on exposed skin. If you feel unwell after working with this product, consult your doctor and show this label.
Other precautions
Deltamethrin is very toxic to dung, fauna, aquatic organisms and honey bees, is persistent in soils and may accumulate in sediments. The risk to aquatic ecosystems and dung fauna can be reduced by avoiding too frequent and repeated use of deltamethrin (and other synthetic pyrethroids) in cattle and sheep, e.g. by using only a single treatment per year on the same pasture. The risk to aquatic ecosystems will be further reduced by preventing treated sheep from entering watercourses for one hour immediately after treatment.
Adverse reactions
Application site reactions, including squamosis and pruritus have been very rarely seen in cattle during the 48 hours after treatment.
Use during pregnancy, lactation or lay
The safety of the veterinary medicinal product has not been established during pregnancy and lactation.
Laboratories studies in rat and rabbits have not produced any evidence of teratogenic effects.
Use only according to a benefit/risk assessment by the responsible veterinarian.
Interactions
Do not use with any other insecticide or acaricide. Especially, in combination with organo-phosphorous compounds, the toxicity of deltamethrin is enhanced.
Amounts to be administered and administration route
For external Pour-on use.
Dose:
Cattle: 100 mg of deltamethrin per animal corresponding to 10 ml of product.
Sheep: 50 mg of deltamethrin per animal corresponding to 5 ml of product
Lambs (under 10 kg bodyweight or 1 month of age): 25 mg of deltamethrin per animal corresponding to 2.5 ml of product.
Administration:
The product should be applied using an appropriate device :
- for the 0.5 litre and 1 litre bottles, the product is supplied with a dosing cup
- for the 2.5 litre bottle and the 2.5 litre and 4.5 litre flexible pouches, it is recommended to use an appropriate dosing gun. The flexible pouches should be carried in an appropriate rucksack.
An appropriate applicator should comply with the following specifications :
- it should deliver doses of 2.5 ml, 5 ml and 10 ml.
- it should be supplied with a flexible hose of internal diameter between 10 mm and 14 mm.
Cattle : Apply a 10 ml dose using an appropriate applicator.
Sheep : Apply one 5 ml dose using an appropriate applicator.
Lambs : Apply one 2.5 ml dose using an appropriate applicator.
Application site :
Apply the product along the mid-line of the back at the level of the shoulders.
See following specific indication directions.
Lice on cattle: One application will generally eradicate all lice. Complete clearance of all lice may take 4 - 5 weeks during which time lice hatch from the eggs and are killed. A very few lice may survive on a small minority of animals.
Flies on cattle: Where horn-flies predominate, treatment and prevention of infestations can be expected for 4 - 8 weeks.
Ticks on sheep: Application to the mid-point of the shoulders will provide treatment and prevention of infestations by ticks attaching to animals of all ages, for up to 6 weeks after treatment.
Keds and lice on sheep: Application to the mid-point of the shoulders of sheep in short or long fleece will reduce the incidence of a biting louse or ked infestation over a 4 - 6 week period after treatment.
It is advisable to:
- treat shortly after shearing (animals with short fleece),
- keep treated sheep separated from untreated sheep to avoid re-infestation.
N.B. For treatment and prevention of infestations by ticks, keds and lice on sheep, the fleece should be parted and the product applied to the skin of the animal.
Established blowfly strike on sheep: Apply directly to the maggot infected area as soon as the fly strike is seen. One application will ensure blowfly larvae are killed in a short time. In the case of more advanced strike lesions, clipping out of stained wool before treatment is advisable.
Lice and ticks on lambs: Application to the mid-line of the back at the level of the shoulders will provide treatment and prevention of infestations by ticks for up to 6 weeks after treatment, and will reduce the incidence of biting lice over a 4-6 week period after treatment.
Overdose
Some adverse effects have been seen following overdose. These include paraesthesia and irritation in cattle, as well as intermittent or attempted urination in young lambs. These have been shown to be mild, transient and resolve without treatment.
Withdrawal periods

Pharmacological particulars
Pharmacotherapeutic group: Ectoparasiticide for topical use, including insecticides. Pyrethrins and pyrethroids.
ATCvet code: QP53AC11
Pharmacodynamic properties
Deltamethrin is a synthetic pyrethroid possessing insecticidal and acaricidal activity. It is one of a large family of pyrethroid esters which have evolved as synthetic analogues of the original insecticidal extracts isolated from powdered pyrethrum flowers. Deltamethrin is an alpha- cyano pyrethroid and is a member of the second generation of pyrethroids in which the overall stability of the molecule is improved with correspondingly increased resistance to photo- and bio-degradation and enhanced insecticidal activity. It is more potently toxic to insects and acarines because of the slower rate of metabolism.
The precise mode of insecticidal activity of pyrethroids remains uncertain, but they are potent neurotoxins in insects, causing failure in sensory coordination and disorganised motor activity, hence the 'knock-down' effect. Pyrethroids are metabolised through oxidative and neurotoxic pathways far more rapidly in mammals, so that neurotoxic effects can only occur at dosages which are many orders of magnitude greater than those required for ectoparasitic activity.
Two physiological mechanisms are likely to contribute to deltamethrin-resistance: mutation of the molecular deltamethrin target or through metabolic enzyme glutathione-S-transferases.
Pharmacokinetic properties
After dermal application, deltamethrin is slightly absorbed through skin of cattle and sheep.
Pyrethroids are metabolised through oxidative and neurotoxic pathways.
The main route of excretion of the absorbed amount in the target animal is the faeces.
Environmental properties
Deltamethrin has the potential to adversely affect non-target organisms. Following treatment, deltamethrin is excreted in faeces. Deltamethrin excretion may take place over a period of 2 to 4 weeks. Faeces containing deltamethrin excreted onto pasture by treated animals may reduce the abundance of dung feeding organisms.
Deltamethrin is toxic to aquatic organisms and honey bees and may accumulate in sediment.
