Flea treatment and prevention (Ctenocephalides felis)
One treatment prevents future flea infestation for 4 weeks. Existing pupae in the
environment may emerge for 6 weeks or longer after treatment is initiated,
depending upon climatic conditions. Therefore, it may be necessary to combine the
treatment with this product with environmental treatments aimed at breaking the flea
life cycle in the surroundings. This can result in a more rapid reduction in the
household flea population. The product should be administered at monthly intervals
when used as part of a treatment strategy for flea allergy dermatitis.

Heartworm prevention (Dirofilaria immitis)
Cats in areas endemic for heartworm, or those which have travelled to endemic
areas, may be infected with adult heartworms. Therefore prior to treatment with this
product, the advice provided in section 4.5 should be considered.
For prevention of heartworm disease, the product must be applied at regular
monthly intervals during the time of the year when mosquitoes (the intermediate
hosts which carry and transmit heartworm larvae) are present. The product may be
administered throughout the year or at least 1 month before the first expected
exposure to mosquitoes. Treatment should continue at regular monthly intervals
until 1 month after the last exposure to mosquitoes. To establish a treatment routine,
it is recommended that the same day or date be used each month. When replacing
another heartworm preventative product in a heartworm prevention programme, the
first treatment with this product must be given within 1 month of the last dose of the
former medication.
In non-endemic areas there should be no risk of cats having heartworm. Therefore,
they can be treated without special precautions.

Roundworm and hookworm treatment (Toxocara cati and Ancylostoma tubaeforme).
In areas endemic for heartworm, monthly treatment may significantly reduce the risk
of re-infection caused by the respective roundworms and hookworms. In areas non-
endemic for heartworm, the product can be used as part of a seasonal prevention
programme against fleas and gastrointestinal nematodes.
Dosage schedule for ferrets:
One 0.4 ml pipette of this product should be administered per animal. Do not exceed
the recommended dose.
The treatment schedule should be based on the local epidemiological situation.
Flea treatment and prevention (Ctenocephalides felis)
One treatment prevents future flea infestation for 3 weeks. Under heavy flea
pressure it may be necessary to repeat administration after 2 weeks.
Heartworm prevention (Dirofilaria immitis)
Ferrets in areas endemic for heartworm, or those which have travelled to endemic
areas, may be infected with adult heartworms. Therefore prior to treatment with this
product, the advice provided in section 4.5 should be considered.
For prevention of heartworm disease, the product must be applied at regular
monthly intervals during the time of the year when mosquitoes (the intermediate
hosts which carry and transmit heartworm larvae) are present. The product may be
administered throughout the year or at least 1 month before the first expected
exposure to mosquitoes. Treatment should continue at regular monthly intervals
until 1 month after the last exposure to mosquitoes.
In non-endemic areas there should be no risk of ferrets having heartworm.
Therefore they can be treated without special precautions.
Method of administration
For external use only.
Remove one pipette from the package. Then hold the pipette in an upright position,
and twist and pull off the cap. Reverse the cap and use it to twist and remove the
seal from the pipette, as shown.

Part the fur on the animal's neck at the base of the skull until the skin is visible. Place
the tip of the pipette on the skin and squeeze the pipette firmly several times to empty
its contents directly onto the skin. Application at the base of the skull will minimise
the opportunity for the animal to lick the product. Apply only to undamaged skin.
therefore the duration of effect might be shorter in these animals.
Brief contact of the animal with water on one or two occasions between monthly
treatments is unlikely to significantly reduce the efficacy of the product. However,
frequent shampooing or immersion of the animal in water after treatment may
reduce the efficacy of the product.
Parasite resistance to any particular class of anthelmintic may develop following
frequent, repeated use of an anthelmintic of that class. Therefore, the use of this
product should be based on the assessment of each individual case and on local
epidemiological information about the current susceptibility of the target species in
order to limit the possibility of a future selection for resistance.
The use of the product should be based on the confirmed diagnosis of mixed
infection (or risk of infection, where prevention applies) at the same time (see also
sections 4.2 and 4.9).

4.5
i) Special precautions for use in animals
The treatment of cats weighing less than 1 kg and ferrets weighing less than 0.8 kg
should be based on a benefit-risk assessment.
There is limited experience on the use of the product in sick and debilitated animals,
thus the product should only be used based on a benefit-risk assessment for these
animals.
Do not apply in the mouth, in the eyes or the ears of the animal.
Care should be taken that the product is not ingested by animals and does not come
into contact with the eyes or mouth of the recipient and/or other animals.
Consider carefully the correct application method described in section 4.9,
especially that the product should be applied at the base of the skull in order to
minimise the risk for the animal to lick the product.
Do not allow recently treated animals to groom each other. Do not allow treated
animals to come into contact with untreated animals until the application site is dry.
It is recommended that cats and ferrets living in, or travelling to areas endemic for
heartworm are treated monthly with the product to protect them from heartworm
disease.
Whilst the accuracy of diagnosis of heartworm infection is limited, it is recommended
that attempts be made to check the heartworm status of any cat and ferret aged
over 6 months, before beginning prophylactic treatment, as use of the product on
cats or ferrets which have adult heartworms may cause serious adverse effects,
including death. If adult heartworm infection is diagnosed, the infection should be
treated in accordance with current scientific knowledge.
In certain individual cats
cases concomitant supportive treatment is necessary as treatment with the product
alone may not be sufficient to prevent death of the animal.
The safety of the product has not been established in cats with severe clinical
signs of . Use of the product in such cases should be based on the
benefit-risk assessment of the veterinarian.
Imidacloprid is toxic for birds, especially canaries.
ii) Special precautions to be taken by the person administering the veterinary
medicinal product to animals
Avoid contact with skin, eyes or mouth.
Do not eat, drink or smoke during application.

In order to prevent children getting access to pipettes, keep the pipette in the
original packaging until ready for use and dispose of used pipettes immediately.
Wash hands thoroughly after use.
After application do not stroke or groom animals until the application site is dry.
This may be ensured by treating animals in the evening. Do not allow recently
treated animals to sleep with owners, especially children.
In case of accidental spillage onto skin, wash off immediately with soap and water.
People with known hypersensitivity to benzyl alcohol, imidacloprid or moxidectin
should administer the product with caution. In very rare cases the product may
cause skin sensitisation or transient skin reactions (for example numbness,
irritation or burning/tingling sensation).
In very rare cases the product may cause respiratory irritation in sensitive
individuals. If the product accidentally gets into eyes, they should be thoroughly
flushed with water. If skin or eye symptoms persist or if the product is accidentally
swallowed, seek medical advice immediately and show the package leaflet or the
label to the physician.
iii) Other precautions
The solvent in the product may stain or damage certain materials including leather,
fabrics, plastics and finished surfaces. Allow the application site to dry before
permitting contact with such materials.
4.6
Use of the product may result in transient pruritus in cats. On rare occasions greasy
fur, erythema and vomiting can occur. These signs disappear without further
treatment. The product may, in rare cases, cause local hypersensitivity reactions. If
the animal licks the application site after treatment, neurological signs (most of
which are transient) may be observed in very rare cases (see section 4.10).
The product tastes bitter. Salivation may occasionally occur if the animal licks the
application site immediately after treatment. This is not a sign of intoxication and
disappears within some minutes without treatment. Correct application will minimise
licking of the application site.
The product may in very rare cases cause at the application site a sensation
resulting in transient behavioural changes such as lethargy, agitation, and
inappetence.
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).
