- Treatment of tick infestations (Ixodes ricinus, , Dermacentor
reticulatus, Rhipicephalus sanguineus). The product has a persistent acaricidal
efficacy for up to 4 weeks against ticks.
- Treatment of infestations with biting lice (Trichodectes canis).
For external use only, topical spot-on application to the skin. Animals should be
weighed accurately prior to treatment.
One pipette of 4.02 ml (S) per dog weighing over 40 kg and up to 60 kg,
corresponding to a minimum recommended dose of 6.7 mg/kg for fipronil and 6
mg/kg for (S)-methoprene.
Do not overdose.
In the absence of safety studies, the minimum treatment interval is 4 weeks.
Method of administration:
Hold the pipette upright. Tap the narrow part of the pipette to ensure the contents
remain within the main body of the pipette. Snap back the tip. Part the coat on the
back of the animal at the base of the neck in front of the shoulder blades until the
skin is visible. Place the tip of the pipette on the skin and squeeze the pipette several
times to empty its contents completely and directly onto the skin in one spot.
Temporary changes to the coat (clumped/greasy hair) may be noted at the
application site.
In the absence of available data, do not use the product on puppies less than
8 weeks old and/or weighing less than 2 kg.
Do not use on sick (e.g. systemic diseases, fever) or convalescent animals.
Do not use in rabbits, as adverse reactions, including death, could occur.
In the absence of studies, the use of the product is not recommended in non-target
species.
This product is specifically developed for dogs. Do not use in cats and ferrets, as this
could lead to overdosing.
Do not use in known cases of hypersensitivity (allergy) to the active substances
(Fipronil or (S)-methoprene) or to any other excipients (ingredients).
Among the very rare suspected adverse reactions, transient skin reactions on the
application site (skin discoloration, local hair loss, itching, redness) and general
itching or hair loss have been reported after use. Excessive salivation, reversible
nervous signs (increased sensitivity to stimulation, depression, other nervous signs),
vomiting or respiratory symptoms have also been observed after use.
If licking occurs, a brief period of excessive salivation may be observed due mainly to
the nature of the carrier. The frequency of adverse reactions is defined using the
following convention:
- very common (more than 1 in 10 animals treated displaying adverse reaction(s))
- 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).

Bathing/immersion in water within 2 days after application of the product and more
frequent bathing than once a week should be avoided, as no study has been
performed to investigate how this affects the efficacy of the product. Emollient
shampoos can be used prior to treatment but reduce the duration of protection
against fleas to approximately 5 weeks when used weekly after application of the
product. Weekly bathing with a 2% chlorhexidine medicated shampoo did not affect
efficacy against fleas during a 6 weeklong study.
Fleas from pets often infest the animal's basket, bedding and regular resting areas
such as carpets and soft furnishings which should be treated, in case of massive
infestation and at the beginning of the control measures, with a suitable insecticide
and vacuumed regularly. When treating infestations of parasites, all in-contact
animals should be treated with an appropriate product at the same time.

Special precautions for use in animals
For external use only. Do not administer orally.
Avoid contact with the animal's eyes. If the product is in contact with eyes, rinse
immediately with plenty of water.
It is important to make sure that the product is applied to an area where the animal
cannot lick it off and to make sure that animals do not lick each other following
treatment. Do not apply the product on wounds or skin lesions.
The attachment of single ticks after treatment cannot be ruled out . Therefore, the
transmission of infectious diseases cannot be completely excluded if conditions are
unfavourable.
For use during pregnancy, lactation or lay see section 4.7.

product to animals
Keep the pipettes in the original packaging until ready to use and dispose of used

People with a known hypersensitivity (allergy) to insecticides or alcohol should avoid
contact with the product.
This product can cause mucous membrane, skin and eye irritation. Therefore,
contact of the product with mouth, skin and eyes should be avoided.

leaflet or label to the physician.

sleep with owners, especially children.
Do not smoke, drink or eat during application.
Other precautions
