-Trichodectes canis).
One pipette of 4.02 ml (402 mg fipronil + 361.8 mg (S)-methoprene) per dog
weighing over 40 kg corresponding to a minimum recommended dose of 6.7 mg/kg
for fipronil and 6 mg/kg for (S)-methoprene, by topical application to the skin.
In the absence of safety studies, the minimum treatment interval is 4 weeks.
Method of administration:
1. Remove the pipette from its packaging. Hold the pipette in an upright position,
twist and pull the cap off.
2. Turn the cap around and place the other end of the cap back on the pipette.
Push and twist the cap to break the seal, then remove the cap from the pipette.
3. 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 onto 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, the veterinary medicinal product should not be used
on puppies less than 8 weeks old and/or weighing less than 2 kg.
Do not use in sick (e.g. systemic diseases, fever) or convalescent animals.
Do not use in cases of hypersensitivity to the active substances or to any of the
excipients.
Do not apply on wounds or damaged skin.
Do not use in cats and ferrets, as this could lead to overdosing.

Reporting adverse events is important. It allows continuous safety monitoring of a
veterinary medicinal product. Reports should be sent, preferably via a veterinarian, to
either the marketing authorisation holder or its local representative or the national
competent authority via the national reporting system. See the package leaflet for
respective contact details.
AN: 03064/2024 and 03049/2024Page 4 of 7
Bathing/immersion in water within 2 days after application of the veterinary medicinal
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 veterinary
medicinal 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 veterinary medicinal product. Weekly bathing with a 2%
chlorhexidine medicated shampoo did not affect efficacy against fleas during a 6
weeks long study.
There may be an attachment of a few ticks. For this reason, a transmission of
infectious diseases cannot be completely excluded if conditions are unfavourable.
When treating infestations of parasites, all in-contact animals should be treated with
an appropriate veterinary medicinal product at the same time. 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.

Special precautions for safe use in the target species:
Avoid contact with the animal's eyes.
It is important to make sure that the veterinary medicinal 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 overdose.

Special precautions to be taken by the person administering the veterinary medicinal
product to animals:
This veterinary medicinal product can cause mucous membrane, skin and eye
irritation. Therefore, contact of the veterinary medicinal product with mouth, skin and
eyes should be avoided.
People with a known hypersensitivity (allergy) to fipronil, S-methoprene, insecticides
or alcohol should avoid contact with the veterinary medicinal product. Avoid contents
coming into contact with the fingers. If this occurs, wash hands with soap and water.
After accidental ocular exposure the eye should be rinsed carefully in clean water.
If the veterinary medicinal product is accidentally swallowed, seek medical advice
immediately and show the package leaflet to the physician.
Wash hands after use.
Do not smoke, drink or eat during application.
Treated animals should not be handled until the application site is dry, and children
should not be allowed to play with treated animals until the application site is dry. It is
therefore recommended that animals are not treated during the day, but should be
treated during the early evening, and that recently treated animals are not allowed to
sleep with owners, especially children.
Keep pipettes in original packaging until ready to use.
Special precautions for the protection of the environment:
Dogs should not be allowed to swim in watercourses for 2 days after application (see
section 5.5).
Do not use simultaneously with other flea products which are applied directly on to
the animal.
