ricinus) infestations in cats.
The veterinary medicinal product has a persistent insecticidal efficacy for up to 4
weeks against fleas (Ctenocephalides spp.) and acaricidal efficacy for up to 4 weeks
against and for up to 1 week against Dermacentor reticulatus and
Rhipicephalus sanguineus. If Rhipicephalus sanguineus ticks are present when the
veterinary medicinal product is applied, all the ticks may not be killed within the first
48 hours but they may be killed within a week.
Administer by topical application to the skin 1 pipette of 0.5 ml per animal.
Method of administration:
Remove the pipette from the triplex bag. 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 hairs of the animal between the shoulder blades to make the skin
visible. Place the tip of the pipette on the skin and squeeze gently to empty its
contents onto the skin, preferably at two spots, one at the base of the skull and a
second 2-3 cms further back.
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 which normally disappears within 24 hours.
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 veterinary medicinal product should not be used
on kittens less than 2 months old and/or weighing less than 1 kg.
Do not use on sick (e.g. systemic diseases, fever…) or convalescent animals.
Do not use in rabbits, as adverse reactions and even death could occur.
Do not use in cases of hypersensitivity to the active substance, dimethyl sulfoxide or
to any of other excipients.
Cats:
Very rare
(<1 animal / 10,000 animals
treated, including isolated
reports):
Application site reactions (squamosis
, alopecia
,
pruritus
, erythema
)
Generalised pruritus or alopecia
Hypersalivation
, vomiting
Hyperesthesia
, depression
, other nervous
signs
Respiratory signs
Transient.
If licking occurs, a brief period of hypersalivation may be observed.
Reversible.
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 also section 16 of the
package leaflet for respective contact details.
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 veterinary medicinal product on wounds or damaged skin.
Animals should be weighed accurately prior to treatment.

Special precautions for safe use in the target species:
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 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 tick 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.
No data on the effect of bathing/shampooing on the efficacy of the veterinary
medicinal product in cats are available. However, based on information available for
dogs, weekly immersion in water for one minute reduces the period of persistent
insecticidal efficacy against fleas by one week.
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 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 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 a 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 the original packaging and dispose of used pipettes immediately.
Special precautions for the protection of the environment:
Not applicable.
None known.
Store in the original container in order to protect from light and moisture.
The product should be maintained at room temperature (above 14°C) for
approximately one hour prior to administration.
Not applicable.
