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 veterinary
medicinal product treatment 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 veterinary medicinal product should be administered
at monthly intervals when used as part of a treatment strategy for flea allergy
dermatitis.
Treatment of biting lice (Trichodectes canis)
A single dose should be administered. A further veterinary examination 30 days after
treatment is recommended as some animals may require a second treatment.
Treatment of ear mite infestation (Otodectes cynotis)
A single dose of the veterinary medicinal product should be administered. Loose
debris should be gently removed from the external ear canal at each treatment. A
further veterinary examination 30 days after treatment is recommended as some
animals may require a second treatment. Do not apply directly to the ear canal.
Treatment of sarcoptic mange (caused by Sarcoptes scabiei var. canis)
A single dose should be administered twice 4 weeks apart.
Treatment of demodicosis (caused by Demodex canis)
The administration of a single dose every 4 weeks for 2 to 4 months is efficacious
against
particularly in mild to moderate cases. Especially severe cases may require more
prolonged and more frequent treatment. To achieve the best possible response in
these severe cases, at the discretion of the veterinarian, the veterinary medicinal
product can be applied once a week and for a prolonged time. In all cases it is
essential that the treatment should be continued until skin scrapings are negative on
at least 2 consecutive monthly occasions. Treatment should be stopped in dogs that
show no improvement or do not respond in mite count after 2 months treatment.
Alternative treatment should be administered. Seek the advice of your veterinarian.
As demodicosis is a multi-factorial disease, where possible, it is advisable to also
treat any underlying disease appropriately.
Prevention of heartworm disease (D. immitis)
Dogs in areas endemic for heartworm, or those which have travelled to endemic
areas, may be infected with adult heartworms. Therefore prior to treatment with the
veterinary medicinal product, the advice provided in section 4.5 should be
considered.
For prevention of heartworm disease, the veterinary medicinal product must be
applied at regular monthly intervals during the time of the year when mosquitoes (the
intermediate hosts which carry and transmit D. immitis larvae) are present. The
veterinary medicinal product may be administered throughout the year. The first dose
may be given after first possible exposure to mosquitoes, but not more than one
month after this exposure. 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 the veterinary medicinal 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 dogs having heartworm. Therefore,
they can be treated without special precautions.
Prevention of cutaneous dirofilariosis (skin worm) (D. repens)
For prevention of cutaneous dirofilariosis, the veterinary medicinal product must be
applied at regular monthly intervals during the time of the year when mosquitoes (the
intermediate hosts which carry and transmit D. repens larvae) are present. The
veterinary medicinal 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.
Treatment of microfilariae (D. immitis)
The veterinary medicinal product should be administered monthly for two consecutive
months.
Treatment of cutaneous dirofilariosis (skin worm) (adult stages of Dirofilaria repens)
The veterinary medicinal product should be administered monthly for six consecutive
months.
Reduction of microfilariae (skin worm) (D. repens)
The veterinary medicinal product should be administered monthly for four
consecutive months.
Treatment and prevention of Angiostrongylus vasorum
A single dose should be administered. A further veterinary examination 30 days after
treatment is recommended as some animals may require a second treatment.
In endemic areas regular monthly applications will prevent angiostrongylosis and
patent infection with Angiostrongylus vasorum.
Treatment of Crenosoma vulpis
A single dose should be administered.
Prevention of spirocercosis (Spirocerca lupi)
The veterinary medicinal product should be administered monthly.
Treatment of Eucoleus (syn. Capillaria) boehmi (adults)
The veterinary medicinal product should be administered monthly for two consecutive
months. It is advisable to prevent auto-coprophagia between the two treatments in
order to prevent possible reinfection.
Treatment of the eye worm Thelazia callipaeda (adults)
A single dose of the veterinary medicinal product should be administered.
Roundworm, hookworm and whipworm treatment Toxocara canis, Ancylostoma
caninum, Uncinaria stenocephalaToxascaris leonina and Trichuris vulpis)
In areas endemic for heartworm, monthly treatment may significantly reduce the risk
of re-infection caused by the respective round-, hook- and whipworms. In areas non-
endemic for heartworm, the veterinary medicinal product can be used as part of a
seasonal prevention programme against fleas and gastrointestinal nematodes.
Studies have shown that monthly treatment of dogs will prevent infections caused by
Uncinaria stenocephala.
Method of administration
External use.
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.

With the dog in a standing position, part the coat between the shoulder blades until
the skin is visible. Wherever possible apply to undamaged skin. Place the tip of the
pipette on the skin and squeeze the pipette firmly several times to empty its contents
directly onto the skin.
Do not use in puppies under 7 weeks of age.
Do not use in cases of hypersensitivity to the active substances or to any of the
excipients.
Do not use in dogs classified as Class 4 for heartworm disease as the safety of the
veterinary medicinal product has not been evaluated in this animal group.
Do not use in cats. Instead, the corresponding “Advocate for cats” product (0.4 or 0.8
ml), which contains 100 mg/ml imidacloprid and 10 mg/ml moxidectin, must be used
for cats.
Do not use in ferrets. Only “Advocate for small cats and ferrets” (0.4 ml) must be
used for ferrets.
Do not use on canaries.

These signs are common in heartworm positive dogs with microfilaraemia, and
there is a risk of gastrointestinal signs and severe respiratory signs that may require
prompt veterinary treatment.
These signs disappear without further treatment.
Transiently noted and related to sensation at application site.
This is not a sign of intoxication and disappears within minutes without treatment.
Correct application will minimise licking of the application site.
Most neurological signs occur transiently.
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 the national competent authority via the
national reporting system. See the package leaflet for respective contact details.
Brief contact of the animal with water on one or two occasions between monthly
treatments is unlikely to significantly reduce the efficacy of the veterinary medicinal
product. However, frequent shampooing or immersion of the animal in water after
treatment may reduce the efficacy of the veterinary medicinal product.
The possibility that other animals in the same household can be a source of re-
infection with fleas, mites, gastrointestinal nematodes, heartworm and/or lungworm
should be considered, and these should be treated as necessary with an appropriate
product.
Unnecessary use of antiparasitics or use deviating from the instructions given in the
SPC may increase the resistance selection pressure and lead to reduced efficacy.
The decision to use the product should be based on confirmation of the parasitic
species and burden, or of the risk of infestation based on its epidemiological features,
for each individual animal.
Efficacy against adult Dirofilaria repens has not been tested under field conditions.

Special precautions for safe use in the target species:
The treatment of animals weighing less than 1 kg should be based on a benefit-risk
assessment.
There is limited experience on the use of the veterinary medicinal product in sick and
debilitated animals, thus the veterinary medicinal 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 veterinary medicinal 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 3.9, especially
that the veterinary medicinal product should be applied to the site specified in order
to minimise the risk for the animal to lick the veterinary medicinal 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.
When the veterinary medicinal product is applied in 3 to 4 separate spots (see
section 3.9), specific care should be taken to prevent the animal licking the
application sites.
This veterinary medicinal product contains moxidectin (a macrocyclic lactone),
therefore special care should be taken with Collie or Old English Sheep dogs and
related breeds or crossbreeds, to correctly administer the veterinary medicinal
product as described under section 3.9; in particular, oral uptake by Collie or Old
English Sheep dogs and related breeds or crossbreeds should be prevented.
The safety of the veterinary medicinal product has only been evaluated in dogs
classified as either Class 1 or 2 for heartworm disease in laboratory studies and in a
few Class 3 dogs in a field study. Therefore the use in dogs with obvious or severe
symptoms of the disease should be based on a careful benefit-risk assessment by
the treating veterinarian.
Although experimental overdosage studies have shown that the veterinary medicinal
product may be safely administered to dogs infected with adult heartworms, it has no
therapeutic effect against adult Dirofilaria immitis. It is therefore recommended that
all dogs 6 months of age or more, living in areas endemic for heartworm, should be
tested for existing adult heartworm infection before being treated with the veterinary
medicinal product. At the discretion of the veterinarian, infected dogs should be
treated with an adulticide to remove adult heartworms. The safety of the veterinary
medicinal product has not been evaluated when administered on the same day as an
adulticide.
Imidacloprid is toxic for birds, especially canaries.
Special precautions to be taken by the person administering the veterinary medicinal
product to animals
This veterinary medicinal product can cause skin, eye, or mouth irritation.
In very rare cases the veterinary medicinal product may cause skin sensitisation or
transient skin reactions (for example numbness, irritation or burning/tingling
sensation).
In very rare cases the veterinary medicinal product may cause respiratory irritation in
sensitive individuals.
People with a known hypersensitivity to benzyl alcohol, imidacloprid or moxidectin
should administer the veterinary medicinal product with caution.
Avoid contact with skin, eyes or mouth.
Do not eat, drink or smoke during application.
Wash hands thoroughly after use.
After application do not stroke or groom animals until the application site is dry.
In case of accidental spillage onto skin, wash off immediately with soap and water.
If the veterinary medicinal product accidentally gets into eyes, they should be
thoroughly flushed with water.
If skin or eye symptoms persist, or the veterinary medicinal product is accidentally
swallowed, seek medical advice immediately and show the package leaflet or label to
the physician.
Special precautions for the protection of the environment:
The veterinary medicinal product should not enter water courses as imidacloprid and
moxidectin may be dangerous for fish and other aquatic organisms. Dogs should not
be allowed to swim in surface waters for 4 days after treatment.
Other precautions:
The solvent in the veterinary medicinal 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.
During treatment with the veterinary medicinal product no other antiparasitic
macrocyclic lactone should be administered.
No interactions between the veterinary medicinal product and routinely used
veterinary medicinal products or medical or surgical procedures have been observed.
Safety of the veterinary medicinal product when administered on the same day as an
adulticide to remove adult heartworms has not been evaluated.
Do not store above 30 °C.
Not applicable.
