For the treatment of infestations by fleas (Ctenocephalides felis). The product shows

immediate insecticidal effect and persistent insecticidal activity against new

infestations by adult fleas for up to 8 weeks.

The product has a persistent acaricidal efficacy against Ixodes ricinus for up to 2

weeks, Rhipicephalus sanguineus for up to 3 weeks and Dermacentor reticulatus for

up to 4 weeks. If ticks of these species are present when the product is applied, all

ticks will not be killed within the first 48 hours but they may be killed within a week.

The product can be used as part of a treatment programme for Flea Allergy

Dermatitis where this has been previously diagnosed by a Veterinary Surgeon.

In the absence of available data, the product should not be used in puppies less than

8 weeks old.

Do not use in sick (systemic diseases, fever…) or convalescent animals.

Do not use in rabbits, as adverse reactions and even death could occur.

This product is specifically developed for dogs. Do not use in cats, as this could lead

to overdosing.

Do not use in cases of known hypersensitivity to the active or to any of the excipients.

4.4 Special warnings for each target species

The product does not prevent ticks from attaching to the animals, but ticks may be

killed in the first 24-48 hours after attachment prior to full engorgement and

therefore minimising the risk of transmission of diseases. Once dead, ticks will often

drop off the animal, but any remaining ticks may easily be removed by a gentle pull.

When used as part of a strategy for the treatment of Flea Allergy Dermatitis, monthly

applications to the allergic patient and to other dogs in the household are


For optimal control of flea infestation in multi-pet household, all dogs and cats in the

house should be treated with a suitable insecticide.

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 of the animal because the maintenance of

effectiveness of the product in these cases has not been tested.

4.5 Special precautions for use

(i) 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.

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


Health Products Regulatory Authority

Do not apply the product on wounds or damaged skin.

(ii) Special precautions to be taken by the person administering the veterinary

medicinal product to the animals

This product can cause mucous membrane and eye irritation. Therefore, contact of

the product with the mouth and eyes should be avoided.

In cases of accidental eye contact, immediately and thoroughly rinse the eye with

plain water. If eye irritation persists seek medical advice and show the package leaflet

or the label to a physician.

People with a known hypersensitivity to fipronil or excipients (section 6.1) should

avoid contact with the veterinary product.

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.

Treated animals should not be handled until this 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.

(iii) Other precautions

Fipronil may adversely affect aquatic organisms. Dogs should not be allowed to swim

in watercourses for 2 days after application.

The alcohol carrier may have adverse effect on painted, varnished or other household

surfaces or furnishings.

This product is flammable. Keep away from heat, sparks, open flame or other sources

of ignition.

4.6 Adverse reactions (frequency and seriousness)

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 (skin discoloration, local alopecia, pruritus, erythema)

Health Products Regulatory Authority

23 August 2017


Page 4 of 8

and general pruritus or alopecia have been reported after use. Exceptionally,

hypersalivation, reversible neurological signs (hyperaesthesia, depression, nervous

signs), vomiting or respiratory signs 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 reaction(s) 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).

4.7 Use during pregnancy, lactation or lay

Laboratory studies using fipronil have not shown any evidence of teratogenic or

embryotoxic effects. Studies have not been carried out with this product in pregnant

and lactating animals. Use in pregnancy and lactation only in accordance with

professional veterinary advice and a benefit/risk assessment.

4.8 Interaction with other medicinal products and other forms of interaction

None known.

4.9 Amounts to be administered and administration route

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 the animals do not lick each other following


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 48 hours post application.

For the optimal control of infestation by flea and or/tick the treatment schedule can

be based on local epidemiological situation.

In the absence of safety studies, the minimum treatment interval is 4 weeks.

4.10 Overdose (symptoms, emergency procedures, antidotes), if necessary

No adverse effects were observed in target animal safety studies in 8 week old

puppies, growing dogs and dogs weighing circa 2 kg treated on 3 occasions at five

times the recommended dose. The risk of experiencing adverse effects (see section

4.6) may however increase when overdosing, so animals should always be treated

with the correct pipette size according to bodyweight.

4.11 Withdrawal period(s)

Not applicable.

5.1 Pharmacodynamic properties

Fipronil is an insecticide/acaricide in the phenylpyrazole family. It acts by inhibiting

the GABA complex, binding to the chloride channel and thereby blocking pre- and

post-synaptic transfer of chloride ions across the cell membrane. This results in

uncontrolled activity of the central nervous system and death in insects and acarids.

Fipronil exhibits insecticidal activity against fleas (Ctenocephalides felis), and

acaricidal activity against ticks (Rhipicephalus sanguineus, Dermacentor reticulatus,

Ixodes ricinus) in the dog.

Newly arriving fleas are killed within 24 hours of landing on the animal. Ticks if

already present at the time of application of the product, may not always be killed in

the first 48 hours, however will be killed within 9 days post treatment.

The product is effective against flea infestation (Ctenocephalides felis) for

approximately 8 weeks and against tick infestations for up to 4 weeks (see

indications for use), depending on the tick species and the level of challenge.

5.2 Pharmacokinetic properties

After a local application of fipronil to the dog, it is slightly absorbed through the skin.

Low levels of fipronil may be detected in the plasma, with a very high variability

between dogs. After application, there is a good distribution of the chemical on the

hair, presenting a good gradient of concentration between the application zone and

the peripheral area.

Fipronil is mainly metabolised to its sulfone derivative (RM1602), which also

possesses insecticidal and acaricidal properties.

The concentrations of fipronil on the hair decrease with time.
