infestations.
For treatment of Trichodectes canis
killed within 2 days.
Insecticidal efficacy against new infestations with adult fleas persists for up to 8
weeks.
The veterinary medicinal product has a persistent acaricidal efficacy for up to 3
weeks against Ixodes ricinus sanguineus
and Dermacentor reticulatus. If ticks of some species (Ixodes ricinus, Rhipicephalus
sanguineus) are present when the veterinary medicinal product is applied, all the
ticks may not be killed within the first 48 hours.
The veterinary medicinal product can be used as part of a treatment strategy for the
control of Flea Allergy Dermatitis (FAD) where this has been previously diagnosed by
a veterinary surgeon.
AN: 00885/2025 & 00893/2025
Administer by topical application to the skin according to the bodyweight as follows:
1 pipette of 2.68 ml per dog weighing over 20 kg up to 40 kg bodyweight.
To ensure a correct dosage, body weight should be determined as accurately as
possible.
Method of administration:
Remove the pipette from its packaging. Hold the pipette in an upright position, twist
and pull the cap off. 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. Spread the animal hairs in the area between the shoulder blades to make the
skin visible. Put the tip of the pipette onto the skin and press the unit-dose pipette
several times to empty its contents directly onto the skin at one or two spots.
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.
The hair should be parted and the veterinary medicinal product applied to the skin.
Temporary changes to the coat (clumped/greasy hair and/or deposits on the hair)
may be noted at the application site.
AN: 00885/2025 & 00893/2025
Treatment schedule:
For optimal control of flea and/or tick infestation the treatment schedule can be based
on the local epidemiological situation.
In the absence of safety studies, the minimum treatment interval is 4 weeks.
Do not use in puppies less than 2 months old and/or weighing less than 2 kg in the
absence of available data.
Do not use in sick (e.g. systemic diseases, fever…) or convalescent animals.
Do not use in rabbits, as adverse reactions and even death could occur.
This veterinary medicinal product is specifically developed for dogs. Do not use in
cats, as this could lead to overdosing.
Do not use in cases of hypersensitivity to the active substance or to any of the
excipients.

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
AN: 00885/2025 & 00893/2025
competent authority via the national reporting system. See the package leaflet for
respective contact details.
Bathing/immersion in water within two days after application of the veterinary
medicinal product should be avoided. After weekly immersions in water for one
minute the period of persistent insecticidal efficacy against fleas was 7 weeks.
The veterinary medicinal product does not prevent ticks from attaching to the
animals. If the animal has been treated prior to exposure to the ticks, the ticks will be
killed in the first 24-48 hours after attachment. This will usually be prior to
engorgement, minimising but not excluding the risk of transmission of diseases.
Once dead, ticks will often drop off the animal, but any remaining ticks may be
removed with a gentle pull.
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 used as part of a strategy for the treatment of Flea Allergy Dermatitis, monthly
applications to the allergic patient and to other dogs and cats in the household are
recommended.
For optimal control of flea infestation in multi-pet household, all dogs and cats in the
household should be treated with a suitable insecticide.

Special precautions for safe use in the target species:
Avoid contact with the animal's eyes. In the case of accidental eye contact,
immediately and thoroughly flush the eyes with water.
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 apply the veterinary medicinal product on wounds or damaged skin.
AN: 00885/2025 & 00893/2025
Special precautions to be taken by the person administering the veterinary medicinal
product to animals:
This veterinary medicinal product can cause mucous membrane and eye irritation.
Therefore, contact between the veterinary medicinal product and the mouth or eyes
should be avoided.
In the case of accidental eye contact, immediately and thoroughly flush the eyes with
water. If eye irritation persists seek medical advice immediately and show the
package leaflet or the label to the physician.
Do not smoke, drink or eat during application.
Avoid contents coming into contact with the fingers. If this occurs, wash off
immediately with soap and water.
Wash hands after use.
People with known hypersensitivity to fipronil or dimethyl sulfoxide or other excipients
should avoid contact with the veterinary medicinal product.
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 should not be
allowed to sleep with owners, especially children.
Keep pipettes in original packaging and dispose of used pipettes immediately.
Special precautions for the protection of the environment:
Fipronil may adversely affect aquatic organisms. Dogs should not be allowed to swim
in water courses for 2 days after application.
