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 animal
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
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.
AN: 03610/2024Page 8 of 13
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 (skinworm) (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 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 application 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 stenocephalaoxascaris 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 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
Spot-on use.
For external use only.
Remove one pipette from the package. Tap the narrow part of the pipette to ensure
the contents are within the main body of the pipette. Snap back the tip of the pipette
to enable the contents to be expelled.
For dogs up to 25 kg:
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.
For dogs of more than 25 kg:
For easy application the dog should be standing. The entire contents of the pipette
should be applied evenly as 3 or 4 spots along the top of the back, from between the
shoulders to the base of the tail. At each spot, part the coat until the skin is visible.
Wherever possible apply to undamaged skin. Place the tip of the pipette on the skin
and gently squeeze the pipette to expel a portion of its contents directly onto the skin.
Do not apply an excessive amount of solution at any one spot, as that could cause
some of the product to run down the animal’s side.
AN: 03610/2024Page 10 of 13
Do not use in case 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
product has not been evaluated in this animal group.
For cats, the corresponding “Imoxat for cat” product, which contains 100 mg/ml
imidacloprid and 10 mg/ml moxidectin, must be used
For ferrets: do not use Imoxat for dogs. Only “Imoxat for small cats and ferrets” (0.4
ml) must be used.
Do not use on canaries.

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 the package leaflet for
respective contact details.
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 risk-benefit 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.
In case of accidental oral uptake, symptomatic treatment should be administered.
There is no known specific antidote. The use of activated charcoal may be beneficial.
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.
AN: 03610/2024Page 4 of 13
This veterinary medicinal product contains moxidectin (a macrocyclic lactone),
therefore special care should be taken with Collies, Old English Sheepdogs 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
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.
People with a known hypersensitivity to benzyl alcohol, imidacloprid or moxidectin
should administer the veterinary medicinal product with caution. 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.
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 the
label to the physician.
AN: 03610/2024Page 5 of 13
Special precautions for the protection of the environment:
The veterinary medicinal product should not enter water courses as this may be
dangerous for fish and other aquatic organisms: moxidectin is highly toxic to aquatic
organisms. Dogs should not be allowed to swim in surface waters for 4 days after
treatment.
Other precautions:
The solvent in Imoxat 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.
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 25°C.
