procedure at one or two points along the cat’s back, preferably at the base of the
head and between the shoulders.

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.
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 disappear within 24 hours post application.
White deposits may also be seen at the site for up to 48 hours after application.
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.
In the absence of available data, the product should not be used 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 in cases of 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.
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.
The 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.
It is advisable to avoid frequent bathing or shampooing because the maintenance of
effectiveness of the product in these cases has not been tested.
When used as part of a strategy for the treatment of Flea Allergy Dermatitis, monthly
applications to the allergic patient and to other cats in the household are
recommended.
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.

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.
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.
Do not smoke, drink or eat during application.
People with known hypersensitivity to fipronil or 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.
Other precautions
The alcohol carrier may have adverse effects on painted, varnished or other
household surfaces or furnishings.
