Cat weightPipette volumeFipronil (mg)Pyriproxyfen (mg)1-6 kg0.5 ml5060>6-12 kg1 ml100120
For a cat weighing more than 6 kg a recommended dose of 1 ml should be applied, which
can be achieved by applying two 0.5 ml pipettes.
Method of administration:
Remove the pipette from the overblister. Hold the pipette upright. Tap the narrow part of
the pipette to ensure that the contents are within the main body of the pipette. Break the
snap-off top of the spot-on pipette along the scored line.
Part the coat on the back of neck area until the skin is visible. Place the tip of the pipette
on the skin and squeeze firmly several times to empty the contents evenly at one or two
spots. Ensure the solution is applied to healthy skin only and avoid superficial application
to the cat’s hair or run off.

Consult your veterinary surgeon if the product fails to control the flea and tick infestation.
However, in the absence of additional safety studies, do not repeat the treatment at
intervals of less than 4 weeks (see section 4.10).
Do not use in rabbits, as adverse reactions and even death could occur.
Do not use in case of hypersensitivity to the active substances or to any of the excipients.
Transient cosmetic effects such as wet appearance or slight scaling may occur at the
application site.
According to the accumulated experience on these active ingredients within spot on
pharmaceutical forms, transient cutaneous reactions at the application site (squamosis
(scaling of the skin), local alopecia (hair loss), pruritus (itchiness), erythema (redness of
the skin), skin discolouration) and general pruritus or alopecia may be observed after use.
In very rare instances, hypersalivation, reversible neurologic symptoms (hyperesthesia
(increased sensitivity to stimuli), depression, nervous symptoms), respiratory signs or
vomiting might occur.
The frequency of adverse reactions is defined using the following convention:
- very common (more than 1 in 10 animals treated displaying adverse reaction(s))
- common (more than 1 but less than 10 animals in 100 animals treated)
- uncommon (more than 1 but less than 10 animals in 1,000 animals treated)
- rare (more than 1 but less than 10 animals in 10,000 animals treated)
- very rare (less than 1 animal in 10,000 animals treated, including isolated reports).

Wetting of the haircoat with water 2 hours before product application and twice during the
claimed period of efficacy against fleas (at two week intervals against adult fleas or four
week intervals against developing flea stages) was investigated during two laboratory
studies. Wetting of the haircoat with water as described did not adversely affect product
effectiveness.
The impact of shampooing on product effectiveness has not been investigated. If a cat
requires shampooing it is recommended that this is done before applying the veterinary
medicinal product.
At the beginning of the control measures, in the case of an infestation, the animal's basket,
bedding and regular resting areas such as carpets and soft furnishings should be treated,
with a suitable insecticide and vacuumed regularly.
To reduce environmental flea challenge, all animals living in the same household should
also be treated with a suitable flea control product.
The product does not prevent ticks from attaching to animals. If the animal has been
treated prior to exposure to the ticks, the ticks will be killed within 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. Any remaining ticks should be carefully
removed, ensuring that their mouth parts are not left within the skin.

Special precautions for use in animals:
For external use only. Do not administer orally.
Animals should be weighed accurately prior to treatment.
The safety of the product has not been established in cats younger than 10 weeks of age
or in cats weighing less than 1.0 kg.
Avoid contact with the animal’s eyes. In the case of accidental eye contact, flush the eyes
with water.
Care should be taken to apply the product correctly as described under section 4.9. Do not
apply the product on wounds or damaged skin. It is important to make sure that the
veterinary medicinal product is applied directly onto an area of dry skin where the animal
cannot lick it off and to make sure that animals do not lick each other following treatment.
The use of the product has not been studied in sick or debilitated cats. Consult your
veterinary surgeon before using the product if your cat is unwell or currently receiving any
other veterinary treatment.
Inform your veterinary surgeon if you are using this product if s/he provides your cat with
any other medication.
