Treatment of flea (Ctenocephalides spp.) infestations.
Fleas will be killed within 24 h. The product has a persistent insecticidal efficacy for
up to 5 weeks against fleas (Ctenocephalides spp.).
Although no immediate killing effect against ticks has been demonstrated, the
product has shown an acaricidal efficacy against . If ticks of
this species are present when the product is applied, all the ticks may not be killed
within the first 48 hours but they will be killed within a week.
The 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.
Route of administration and dosage:
External use only.
Administer by topical application to the skin 1 pipette of 0.5 ml per animal.

Revised: May 2020
AN: 00114/2020
Remove the pipette from the blister packaging. Hold the pipette in an upright position
and snap off the top section of the cap, thereby opening the pipette.
Part the pet’s coat until the skin is visible. Place the tip of the tube directly against the
bared skin and squeeze gently. Empty approximately half the contents at each of two
points along the cat’s back. The first application point is at the base of the head and
the second application point is between the shoulder blades. Squeeze the tube
several times to ensure dosing is complete. Avoid applying the solution onto the fur
and do not rub into the skin.

Application of the solution as directed minimises the possibility that the animal will lick
the solution off.
Care should be taken to avoid excessive wetting of the hair with the product since
this will cause a sticky appearance of hairs at the treatment spot. However, should
this occur, it will usually disappear within 24-48 hours post application. Crystals may
be seen on the hair and slight scaling may occur within 24-48 hours after application.
Treatment schedule:
For optimal control of flea infestation the treatment schedule can be based on the
local epidemiological situation.
The minimum interval between two treatments is 4 weeks.
Revised: May 2020
AN: 00114/2020
Do not use on kittens less than 2 months old and/or weighing less than 1 kg.
Do not use on sick (systemic diseases, fever…) or convalescent animals.
Do not use in rabbits, as adverse drug reactions and even death could occur.
Do not use on animals with known hypersensitivity to the active substance or to any
of excipients.
If licking occurs, a brief period of hypersalivation may be observed due mainly to the
nature of the carrier.
Among the extremely rare suspected adverse reactions, transient cutaneous
reactions at the application site (squamosis, local alopecia, pruritus, erythema) and
general pruritus or alopecia have been reported after use. Exceptionally,
hypersalivation, reversible neurologic symptoms (hyperesthesia, depression, nervous
symptoms) or vomiting have been observed after use.
The frequency of adverse reactions is defined using the following convention:
- very common (more than 1 in 10 animals displaying adverse reactions during the
course of one treatment)
- common (more than 1 but less than 10 animals in 100 animals)
- uncommon (more than 1 but less than 10 animals in 1,000 animals)
- rare (more than 1 but less than 10 animals in 10,000 animals)
- very rare (less than 1 animal in 10,000 animals, including isolated reports).
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.
Avoid frequent swimming or shampooing the animal because the maintenance of
effectiveness of the product in these cases has not been tested.
For optimum control of flea problems in a multi-pet household, all dogs and cats in
the household should be treated with a suitable insecticide.
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.

Special precautions for use in animals
Avoid contact with the animal’s eyes. In the case of accidental eye contact,
immediately and thoroughly flush the eyes with water.
Do not apply the product on wounds or damaged skin.
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.
Specific studies in cats investigating the safety of the product following repeated
administration or at over-dosage have not been conducted due to the known safety
profile of the active substances and excipients.
Special precautions to be taken by the person administering the veterinary
medicinal product to animals
This product can cause mucous membrane and eye irritation. Therefore, contact
between the 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 and show the package leaflet or
the label to the physician.
Avoid contents coming into contact with the fingers. If this occurs, wash hands with
soap and water. Wash hands after use.

Revised: May 2020
AN: 00114/2020
Do not smoke, drink or eat during application.
Animals or people with a known hypersensitivity to fipronil or any of the other
ingredients should avoid contact with the 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 the original packaging and dispose of used pipettes immediately.
Other precautions

surfaces or furnishings.
