Clinical particulars
Target species
Indications for use
- Persistent flea (Ctenocephalides felis) killing activity for 16 weeks.
- Persistent tick (Ixodes ricinus) killing activity for 6 months.
- Persistent sandfly (Phlebotomus perniciosus) anti-feeding and killing activity for 5.5 months.
Do not use in puppies less than 7 weeks of age. Do not use on dogs with skin lesions. Do not use in cases of hypersensitivity to the active substance or to any of the excipients. Do not use on cats. Deltamethrin is harmful to cats.
Special warnings for each target species
As the collar exerts its full effect after one week, the collar should preferably be fitted one week before animals are likely to become exposed to infestation. Ticks and sandflies will be killed and fall off the host within 48 and 24 hours after exposure respectively without having had a blood meal, as a rule. An attachment of single ticks or bite of single sandflies after treatment cannot be excluded. For this reason, the transmission of infectious diseases by ticks or sandflies cannot be completely excluded if conditions are unfavourable. In case of skin lesions, remove the collar until symptoms have resolved. The influence of shampooing on the duration of efficacy has not been investigated. Occasional contact with water does not reduce the effectiveness of the collar. For optimal control of flea infestations in multi-pet households, all dogs in the household should be treated at the same time. Fleas from pets often infest the animal’s basket, bedding and regular resting areas, such as carpets and soft furnishings. These should be treated in cases of massive infestation and upon the initiation of control measures with a suitable insecticide, and vacuumed regularly.
Special precautions to be taken by the person administering the veterinary medicinal product
Deltamethrin is continuously released from the collar to the skin and fur whilst the collar is being worn. Accidental ingestion of this product may cause adverse reactions, including neurological effects. Keep the product in the original carton. Keep the collar in the sachet until use. Do not smoke, eat or drink while handling the collar. Do not allow children to play with the collar or to put it into their mouths. Immediately dispose of any remnants or cut-offs of the collar. Wash hands with cold water after fitting the collar. Avoid prolonged contact with the collar or dog wearing the collar. This includes sharing a bed with dogs wearing the collar; this is particularly important for children. In case of accidental oral exposure or ingestion, seek medical advice and show the package leaflet or the label to the doctor. Deltamethrin may cause hypersensitivity (allergic) reactions in sensitive people. People with known hypersensitivity to deltamethrin should avoid contact with the veterinary medicinal product and the treated animal. Seek medical advice in case of hypersensitivity reactions.
Other precautions
Deltamethrin is toxic to aquatic organisms. Dogs wearing the collar are not allowed to enter watercourses.
Adverse reactions
In rare cases, local skin reactions (pruritus, erythema, hair loss) involving the neck or the skin in general have been observed. Altered behaviour (e.g. lethargy or hyperactivity) often associated with skin irritation has been reported in very rare cases, too. In very rare occasions, gastrointestinal symptoms such as vomiting, diarrhoea and hypersalivation have been observed. In very rare cases, neuromuscular problems such as ataxia and muscle tremor have been observed. The symptoms usually subside within 48 hours after removal of the collar. If any of these symptoms occur, the collar should be removed and contact with a veterinarian is advised. The frequency of adverse reactions is defined using the following convention: very common (more than 1 in 10 animals treated displaying adverse reaction(s) during the course of one treatment) – common (more than 1 but less than 10 animals in 100 animals treated) – uncommon (more than 1 but less than 10 animals in 1,000 animals treated) – rare (more than 1 but less than 10 animals in 10,000 animals treated) – very rare (less than 1 animal in 10,000 animals treated, including isolated reports).
Use during pregnancy and lactation
Laboratory studies have not produced any evidence of developmental or embryotoxic effect. However, the safety of the veterinary medicinal product has not been established in pregnant dogs. Therefore, the product should be used during pregnancy and lactation only according to the benefit/risk assessment by the responsible veterinarian.
Interaction with other medicinal products
Do not use with other ectoparasiticides (pyrethroids, organophosphates).
Dosage and administration
Dog's size
1 x 0.77g collar
1 x 1.04g collar
For external, cutaneous use only. One collar per dog is to be fastened around the neck. Remove the collar from the protective sachet right before use. Fit the collar around the animal’s neck neither too loose nor too tight: two fingers side-by-side should fit between the collar and the dog’s neck. Cut off any excess length extending beyond 5cm. Check periodically and adjust the fit easily by applying pressure on top of the buckle and then sliding the collar into the correct position.
In the unlikely event of the dog eating the collar, the following symptoms may occur: Uncoordinated movements, tremor, drooling of saliva, vomiting, rigidity of the hindquarters. These symptoms usually subside within 48 hours. For more information concerning symptomatic treatment it is advised to contact your local veterinary surgeon.
