Seresto Collar Dog

The Seresto flea collar for dogs protects for up to eight months against fleas, ticks, and biting lice. The effectiveness of Seresto against fleas depends on the age of the flea. For adult fleas, the protection duration is seven to eight months. The protection duration for flea larvae and ticks is eight months. The risk of Lyme disease is greatly reduced when the collar is worn, as Seresto has a repellent effect against ticks. The repellent effect of Seresto prevents ticks from attaching to the dog's skin. Finally, the collar also reduces the risk of infections transmitted by sandflies for up to eight months.

Additionally, the collar has two more significant advantages: the product is odorless and waterproof. This allows your pet to be taken out in the rain without any issues. For better visibility during walks, we recommend attaching the Seresto reflectors to the collar.

The Action of Seresto

The Seresto flea collar for dogs is for external use only and is available in two sizes. The highest concentration of active ingredients is on the inside of the collar and adheres to the skin's sebum layer. A safety study among users has shown that the collar is safe for use on your dog and poses no danger to other animals or children. It is therefore completely safe to pet your four-legged friend when the collar is worn. However, make sure that a child does not hold the band for longer than fifteen to twenty minutes.

Is Seresto Suitable for Your Dog?

It is recommended not to use the Seresto flea collar on pregnant and lactating dogs. This also applies to puppies younger than seven weeks. This is partly because the available collars are too large for puppies. However, there is a Spot-On alternative available for puppies to protect even the youngest dogs against fleas and ticks. Furthermore, Seresto should not be used if your pet is hypersensitive to any of the active ingredients or excipients. So, be vigilant about this.

How to Apply the Seresto Flea Collar

There are remnants of plastic connecting pieces on the inside of the collar. When applying, it is important to remove these. Then you can put the collar around your dog's neck. Do not fasten the collar too tightly; it is advised to leave about two fingers' width of space between the neck and the collar. You can loop the excess part of the collar and cut it off about two centimeters. When the collar is used on puppies, it is important not to cut the collar too short. Puppies grow quickly, and this way, the collar can be easily adjusted. Once the collar is applied to your pet, the active ingredients will then spread throughout the rest of the body.

Ticks already on the cat prior to treatment may not be killed within 48 hours after collar application and may remain attached and visible. Therefore removal of ticks already on the cat at the time of application is recommended. The prevention of infestations with new ticks starts within two days after application of the collar.

Ideally, the collar should be applied before the beginning of the flea or tick season.

Dogs:

For the treatment and prevention of flea (Ctenocephalides felis) infestation for 7 to 8 months. Efficacy against fleas starts immediately after application of the collar.

Protects the animal’s immediate surroundings against flea larvae development for 8 months.

Seresto can be used as part of a treatment strategy for the control of Flea Allergy Dermatitis (FAD).

The product has persistent acaricidal (killing) efficacy against tick infestations (Ixodes ricinus, Rhipicephalus sanguineus, Dermacentor reticulatus) and repellent (anti-feeding) efficacy against tick infestations (Ixodes ricinus, Rhipicephalus sanguineus) for 8 months. It is effective against larvae, nymphs and adult ticks.

Ticks already on the dog prior to treatment may not be killed within 48 hours after collar application and may remain attached and visible. Therefore removal of ticks already on the dog at the time of application is recommended. The prevention of infestations with new ticks starts within two days after application of the collar.

For treatment of biting/chewing lice (Trichodectes canis) infestation.

Ideally, the collar should be applied before the beginning of the flea or tick season.

5.         CONTRAINDICATIONS

Do not treat kittens less than 10 weeks and puppies less than 7 weeks of age.

Do not use in case of known hypersensitivity to the active substances or to any of the excipients.

6.       ADVERSE REACTIONS

Occasionally slight pruritus and/or erythema may be observed in animals that are not used to wearing collars on the first few days after fitting. Ensure that the collar is not fitted too tightly.

Slight hair loss and mild skin reactions may occur at the application site, which usually recover within 1 to 2 weeks without the need for collar removal. In single cases, a temporary collar removal may be recommended until the symptoms have disappeared.

In cats, initially, slight and transient reactions as depression, change of food intake, salivation, vomiting and diarrhoea might occur in rare cases. As in other topical applications, allergic contact dermatitis might occur in hypersensitive animals.

If you notice any serious effects or other effects not mentioned in this leaflet, please inform your veterinary surgeon.

7.       TARGET SPECIES

Cats, Dogs (≤ 8 kg)

8.       DOSAGE FOR EACH SPECIES, ROUTE(S) AND METHOD OF ADMINISTRATION

Cats and small dogs up to 8 kg body weight receive one collar of 38 cm length.

Dogs above 8 kg receive one Seresto collar for dogs > 8 kg of 70 cm length.

Cutaneous use. One collar per animal to be fastened around the neck. For external use only.

9.       ADVICE ON CORRECT ADMINISTRATION

Remove collar from protective bag directly before use. Unroll collar and make sure that there are no remnants from the plastic connectors inside the collar. Adjust the collar around the animal's neck without tightening it too tight (as a guide, it should be possible to insert 2 fingers between the collar and the neck). Pull excess collar through the loop and cut off any excess length extending beyond 2 cm.

The collar should be worn continuously for the 8 month protection period and should be removed after the treatment period. Check periodically and adjust fit if necessary, especially when kittens/puppies are rapidly growing.

This collar is designed with a safety-closure mechanism. In the unlikely event of a cat being trapped, the cats own strength is sufficient to widen the collar to allow for quick release.

10.     WITHDRAWAL PERIOD

Not applicable.

11.     SPECIAL STORAGE PRECAUTIONS

Keep out of the reach and sight of children.

This veterinary medicinal product does not require any special storage conditions.

Do not use after expiry date stated on the bag and outer box.

12.     SPECIAL WARNING(S)

Ticks will be killed and fall off the host within 24 to 48 hours after infestation without having had a blood meal, as a rule. An attachment of single ticks after treatment cannot be excluded. For this reason, a transmission of infectious diseases by ticks cannot be completely excluded if conditions are unfavourable.

As in all longterm topical products, periods of excessive seasonal hair shedding may lead to transient slight reduction of efficacy by loss of hair-bound portions of the active ingredients. Replenishment from the collar starts immediately so that full efficacy will be re-established without any additional treatment or collar replacement.

For optimum control of flea problems in heavily infested households it may be necessary to treat the environment with a suitable insecticide.

The product is water resistant; it remains effective f if the animal becomes wet. However, prolonged, intense exposure to water or extensive shampooing should be avoided as the duration of activity may be reduced. Studies show that monthly shampooing or water immersion does not significantly shorten the 8 months efficacy duration for ticks after redistribution of the active substances in the coat whereas the product’s flea efficacy gradually decreased, starting in the 5th month.

Laboratory studies with either flumethrin or imidacloprid in rats and rabbits have not produced any effects on fertility or reproduction and showed no teratogenic, or foetotoxic effects. However, the safety of the veterinary medicinal product has not been established in target animals during pregnancy and lactation and in the absence of available data, the product is therefore not recommended in pregnant and lactating bitches or queens.

Due to the nature of the collar overdosage is unlikely and signs of overdosage are not to be expected.

An overdosage of 5 collars around the neck was investigated in adult cats and dogs for an 8 months period and in 10 week old kittens and 7 week old puppies for a 6 months period and no other adverse effects were observed than already described in section “adverse reactions”.

In the unlikely event of the animal eating the collar mild gastrointestinal symptoms (e.g. loose stool) may occur.

Special precautions for persons administering Seresto to animals:

Keep the bag with the collar in the outer packaging until use.

As with any veterinary medicinal product, do not allow small children to play with the collar, or to put it into their mouths. Pets wearing the collar should not be allowed to sleep in the same bed as their owners, especially children.

People with known sensitivity to the ingredients of the collar should avoid contact with the collar.

Immediately dispose of any remnants or cut-offs of the collar (see section “advice on correct administration”).

Wash hands with cold water after fitting the collar.

13.     SPECIAL PRECAUTIONS FOR THE DISPOSAL OF UNUSED PRODUCT OR WASTE MATERIALS, IF ANY

Any unused veterinary medicinal product or waste materials derived from such veterinary medicinal products should be disposed of in accordance with local requirements.

This product should not enter water courses as it may be dangerous for fish and other aquatic organisms.

15.     OTHER INFORMATION

Pack size: one collar

Both active ingredients are slowly and continuously released in low concentrations from the polymer matrix system of the collar towards the animal. Both actives are present in the cat’s or dog’s haircoat in acaricidal/insecticidal concentrations during the entire efficacy period. The active substances spread from the site of direct contact over the entire skin surface. Target animal overdose and serum kinetic studies have established that imidacloprid reached the systemic circulation transiently while flumethrin was mostly not measurable. Oral absorption of both active substances is not relevant for the clinical efficacy.

Activity against fleas starts immediately after application of the collar. In addition to the indications listed above an activity against Ctenocephalides canis and Pulex irritans fleas has been demonstrated.

The product provides repellent (anti-feeding) activity against the claimed ticks, thus preventing repelled parasites from taking a blood meal and thereby indirectly aids in the reduction of the risk of Vector-Borne Disease transmission. In addition to the indications listed above activity has been demonstrated in cats against Ixodes hexagonus and the non-European tick species Amblyomma americanum as well as in dogs against I. hexagonus I. scapularis and the non-European tick species Dermacentor variabilis and the Australian paralysis tick I. holocyclus.

The collars were able to improve the Sarcoptes scabiei infestation in pre-infested dogs leading to a full cure after three months.
