Summary for the public


What is STRONGHOLD?

STRONGHOLD is a spot-on solution that contains the active substance selamectin, which belongs to a class of medicines having an antiparasitic action. Stronghold is available in 2 different concentrations (6% and 12%) and in tubes of various strengths (15, 30, 45, 60, 120 and 240 mg) .The concentration and the strength to use, depends on the weight and species of the animal being treated.


What is STRONGHOLD used for?

STRONGHOLD is used to treat and prevent infestations with parasites that live on the skin or in the fur of cats and dogs, such as fleas and mites, as well as treating worm parasites that live inside the body. It is used in the following ways:

  • to treat and prevent flea infestations in cats and dogs, by killing adult fleas, their larvae and their eggs on the animal, and in the litters of pregnant or nursing cats or dogs. It can also be used as part of treatment for flea allergy dermatitis (skin inflammation) and to help control existing flea infestations, by killing eggs and larvae in the areas to which the animal has access, so breaking the flea life-cycle.
  • to prevent heartworm disease in cats and dogs,
  • to treat ear mites in cats and dogs,
  • to treat adult intestinal roundworms and intestinal hookworms in cats,
  • to treat adult intestinal roundworms in dogs
  • to treat biting lice in dogs and cats,
  • to treat sarcoptic mange (scabies) in dogs,

The contents of the tube are squeezed onto the skin after parting the fur between the shoulder blades. This small volume of liquid is absorbed through the skin and has an effect throughout the animal’s body. The strength used and the number of administrations depend on the weight and species of the animal being treated, and the type of parasite. See the Package Leaflet for further information.


How does STRONGHOLD work?

STRONGHOLD contains selamectin, which is an antiparasitic medicine that belongs to the ‘avermectin’ class. Selamectin activates special proteins called ‘chloride channels’ on the surface of nerve and muscle cells, disrupting their normal electrical activity. This causes the paralysis or death of the parasites.


How has STRONGHOLD been studied?

STRONGHOLD has been studied in the treatment of a wide range of breeds of dog and cat for the parasitic infestations listed above.


What benefit has STRONGHOLD shown during the studies?

STRONGHOLD treatment was found to be effective after a single administration or repeated treatments at monthly intervals, depending on the type of infestation it was being used to treat or prevent.

In field studies, it reduced the flea comb counts by up to 98% in cats and 99% in dogs 90 days after treatment, as well as preventing flea eggs from hatching, and killing and preventing the development of flea larvae. Field studies also showed that STRONGHOLD was 100% effective in preventing heart worm disease in dogs and cats. It is also effective in treating ear mites in cats and dogs. In the treatment of sarcoptic mange in dogs, two treatments given 30 days apart were required to completely eliminate the mites in dogs. STRONGHOLD was also effective in the treatment of adult intestinal hookworms in cats, adult intestinal roundworms in cats and dogs, and biting lice in dogs and cats.

Shampooing or soaking the animal two hours or more after treatment did not affect the medicine’s effectiveness.


What is the risk associated with STRONGHOLD?

In rare cases, STRONGHOLD causes temporary alopecia (hair loss) at the application site in cats. Very rarely, there is also temporary irritation at the application site.

On rare occasions, STRONGHOLD may produce clumping of the hair at the application site or the appearance of a small quantity of a white powder. This does not affect the safety or effectiveness of the medicine.

STRONGHOLD must not be used in animals under six weeks of age. It must also not be used in cats that are suffering from another disease or that are debilitated and underweight for their size and age.


What are the precautions for the person who gives the medicine or comes into contact with the animal?

The Package Leaflet should be read before use. Because it is highly flammable, STRONGHOLD should be kept away from heat, sparks, any open flame or other sources of ignition. Do not smoke, eat or drink while handling STRONGHOLD. Wash hands after use and wash off any product in contact with the skin immediately with soap and water. If STRONGHOLD gets into the eyes, flush the eyes immediately with water and seek medical attention.

Keep treated animals away from fires and other sources of ignition for at least 30 minutes or until the hair coat is dry. Do not touch treated animals until the application area is dry. Keep children away from treated animals for at least 30 minutes or until the hair coat is dry. People with sensitive skin or known allergy to products of this type should handle STRONGHOLD with caution.


Why has STRONGHOLD been approved?

The Committee for Medicinal Products for Veterinary Use (CVMP) agreed that the benefits of STRONGHOLD exceed the risks for the treatment and prevention of parasitic infestations in cats and dogs. The Committee recommended that STRONGHOLD be given a marketing authorisation. The benefit-risk balance may be found in module 6 of this EPAR.

CLINICAL PARTICULARS
4.1 Target species
Dogs, cats
4.2 Indications for use, specifying the target species
Cats and dogs: treatment and prevention of flea infestations caused by Ctenocephalides spp. for one
month following a single administration. This is as a result of the adulticidal, larvicidal and ovicidal
properties of the product. The product is ovicidal for 3 weeks after administration. Through a
reduction in the flea population, monthly treatment of pregnant and lactating animals will also aid in
the prevention of flea infestations in the litter up to seven weeks of age. The product can be used as
part of a treatment strategy for flea allergy dermatitis and through its ovicidal and larvicidal action
may aid in the control of existing environmental flea infestations in areas to which the animal has
access.
Cats and dogs: prevention of heartworm disease caused by Dirofilaria immitis with monthly
administration.
2
STRONGHOLD may be safely administered to animals infected with adult heartworms, however, it is
recommended, in accordance with good veterinary practice, that all animals 6 months of age or more
living in countries where a vector exists should be tested for existing adult heartworm infections
before beginning medication with STRONGHOLD. It is also recommended that dogs should be tested
periodically for adult heartworm infections, as an integral part of a heartworm prevention strategy,
even when Stronghold has been administered monthly. This product is not effective against adult
D. immitis.
Cats and dogs: treatment of ear mites ( O. cynotis ).
Cats: treatment of adult roundworms ( Toxocara cati ) and adult intestinal hookworms ( Ancylostoma
tubaeforme).
Cats: treatment of biting lice infestations (Felicola subrostratus )
Dogs: treatment of biting lice infestations ( Trichodectes canis )
Dogs: treatment of sarcoptic mange (caused by S. scabiei ).
Dogs: treatment of adult intestinal roundworms ( Toxocara canis )
4.3 Contraindications
Do not use in animals under 6 weeks of age. Do not use in cats that are suffering from concomitant
disease, or are debilitated and underweight (for size and age).
4.4 Special warnings for each target species
Animals may be bathed 2 hours after treatment without loss of efficacy.
For ear mite treatment, do not apply directly to the ear canal.
It is important to apply the dose as indicated to minimise the quantity that the animal can lick off. If
significant licking does occur, a brief period of hypersalivation may rarely be observed in cats.
4.5 Special precautions for use
Special precautions for use in animals
This product is to be applied to the skin surface only. Do not administer orally or parenterally.
Do not apply when the animal’s hair coat is wet. However, shampooing or soaking the animal 2 or
more hours after treatment will not reduce the efficacy of the product.
Special precautions to be taken by the person administering the veterinary medicinal product to
animals
Read package leaflet before use.
This product is highly flammable; keep away from heat, sparks, open flame or other sources of
ignition.
Do not smoke, eat or drink while handling the product.
Wash hands after use and wash off any product in contact with the skin immediately with soap and
water. If accidental eye exposure occurs, flush the eyes immediately with water and seek medical
attention.
3
Keep treated animals away from fires and other sources of ignition for at least 30 minutes or until the
hair coat is dry.
Avoid direct contact with treated animals until the application area is dry. Keep children away from
treated animals for at least 30 minutes following application of the product or until the hair coat is
dry.
People with sensitive skin or known allergy to products of this type should handle the product with
caution.
Other precautions
Do not allow treated animals to bathe in water courses until at least two hours after treatment
administration.
4.6 Adverse reactions (frequency and seriousness)
Use of the product in cats has on rare occasions been associated with a mild transient alopecia at the
site of application. On very rare occasions transient focal irritation may also be observed. The
alopecia and irritation are normally self-resolving, but symptomatic therapy may be applicable in
some circumstances.
On rare occasions, application of the product may produce a local temporary clumping of the hair at
the application site and/or an occasional appearance of a small quantity of a white powder. This is
normal and will disappear typically within 24 hours of treatment administration and does not affect
either the safety or efficacy of the product.
Exceptionally, as with other macrocyclic lactones, reversible neurological signs have been observed
after use of the product.
4.7 Use during pregnancy, lactation or lay
STRONGHOLD can be used in breeding, pregnant and lactating cats and dogs.
4.8 Interaction with other medicinal products and other forms of interaction
In extensive field testing no interactions between STRONGHOLD and routinely used veterinary
medicinal products or medical or surgical procedures were observed.
4.9 Amounts to be administered and administration route
For external use only.
Apply topically to the skin at the base of the neck in front of the shoulder blades.
STRONGHOLD should be administered as a single topical application of a unit dose delivering a
minimum of 6 mg/kg selamectin. When concurrent infestations or infections in the same animal are to
be treated with the product, only one topical application of the recommended 6 mg/kg dose should be
administered at any one time. The appropriate length of the treatment period for individual parasites is
specified below.

Flea treatment and prevention (cats and dogs)
Following administration of the product, the adult fleas on the animal are killed, no viable eggs are
produced, and larvae (found only in the environment) are also killed. This stops flea reproduction,
breaks the flea lifecycle and may aid in the control of existing environmental flea infestations in areas
to which the animal has access.
For the prevention of flea infestations, the product should be administered at monthly intervals
throughout the flea season, starting one month before fleas become active. Through a reduction in the
flea population, monthly treatment of pregnant and lactating animals will aid prevention of flea
infestations in the litter up to seven weeks of age.
For use as part of a treatment strategy for flea allergy dermatitis the product should be administered at
monthly intervals.
Prevention of heartworm disease (cats and dogs)
The product may be administered year-round or at least within one month of the animal’s first
exposure to mosquitoes and monthly thereafter until the end of the mosquito season. The final dose
must be given within one month after the last exposure to mosquitoes. If a dose is missed and a
monthly interval between dosing is exceeded then immediate administration of the product and
resumption of monthly dosing will minimise the opportunity for the development of adult heartworms.
When replacing another heartworm preventive product in a heartworm disease prevention programme,
the first dose of the product must be given within a month of the last dose of the former medication.
Treatment of roundworm infections (cats and dogs)
A single dose of the product should be administered.
Treatment of biting lice (cats and dogs)
A single dose of the product should be administered.
Treatment of ear mites (cats)
A single dose of the product should be administered.
5
 
Treatment of ear mites (dogs)
A single dose of the 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.
Treatment of hookworm infections (cats)
A single dose of the product should be administered.
Treatment of sarcoptic mange (dogs)
For complete elimination of the mites, a single dose of the product should be administered for two
consecutive months.
Remove the STRONGHOLD tube from its protective package
Holding the tube upright, firmly depress the cap to puncture the applicator
seal, then remove the cap
Part the hair at the base of your animal’s neck in front of the shoulder blades
to expose a small area of skin
Apply the tip of the STRONGHOLD tube directly to the skin without
massaging. Squeeze the tube firmly to empty the contents in one spot. Avoid
contact between the product and your fingers.
4.10 Overdose (symptoms, emergency procedures, antidotes), if necessary
STRONGHOLD was administered at 10 times the recommended dose, and no undesirable effects
were observed. The product was administered at 3 times the recommended dose to cats and dogs
infected with adult heartworms and no undesirable effects were observed. The product was also
administered at 3 times the recommended dose to breeding male and female cats and dogs, including
pregnant and lactating females nursing their litters and at 5 times the recommended dose to
ivermectin-sensitive collies, and no undesirable effects were observed.

PHARMACOLOGICAL PROPERTIES
Pharmacotherapeutic group: therapeutic antiparasitic agent, ATCvet code: QP54A A05 selamectin
5.1 Pharmacodynamic properties
Selamectin is a semi-synthetic compound of the avermectin class. Selamectin paralyses and/or kills a
wide range of invertebrate parasites through interference with their chloride channel conductance
causing disruption of normal neurotransmission. This inhibits the electrical activity of nerve cells in
nematodes and muscle cells in arthropods leading to their paralysis and/or death.
Selamectin has adulticidal, ovicidal and larvicidal activity against fleas. Therefore, it effectively
breaks the flea life cycle by killing adults (on the animal), preventing the hatching of eggs (on the
animal and in its environment) and by killing larvae (environment only). Debris from selamectin-
treated pets kills flea eggs and larvae not previously exposed to selamectin and thus may aid in the
control of existing environmental flea infestations in areas to which the animal has access.
Activity has also been demonstrated againstheartworm larvae.
5.2 Pharmacokinetic particulars
Following topical administration selamectin is absorbed from the skin reaching maximum plasma
concentrations approximately 1 and 3 days after administration in cats and dogs respectively.
Following absorption from the skin selamectin distributes systemically and is slowly eliminated from
plasma as manifested in detectable plasma concentrations in dogs and cats 30 days after
administration of a single topical dose at 6 mg/kg. The prolonged persistence and slow elimination of
selamectin from plasma is reflected in the terminal elimination half-life values of 8 and 11 days in
cats and dogs respectively. The systemic persistence of selamectin in plasma and the lack of extensive
metabolism provide effective concentrations of selamectin for the duration of the inter-dosing interval
(30 days).

INDICATION(S)
Cats and dogs:
Treatment and prevention of flea infestations caused by Ctenocephalides spp. for one month
following a single administration. This is as a result of the adulticidal, larvicidal and ovicidal
properties of the product. The product is ovicidal for 3 weeks after administration. Through a
reduction in the flea population, monthly treatment of pregnant and lactating animals will also
aid in the prevention of flea infestations in the litter up to seven weeks of age. The product can
be used as part of a treatment strategy for flea allergy dermatitis and through its ovicidal and
larvicidal action may aid in the control of existing environmental flea infestations in areas to
which the animal has access.
39
Prevention of heartworm disease caused by Dirofilaria immitis with monthly administration.
STRONGHOLD may be safely administered to animals infected with adult heartworms,
however, it is recommended, in accordance with good veterinary practice, that all animals 6
months of age or more living in countries where a vector exists should be tested for existing adult
heartworm infections before beginning medication with STRONGHOLD. It is also recommended
that dogs should be tested periodically for adult heartworm infections, as an integral part of a
heartworm prevention strategy, even when Stronghold has been administered monthly. This
product is not effective against adult D. immitis.
Treatment of ear mites ( Otodectes cynotis ).
Cats:
Treatment of biting lice infestations (Felicola subrostratus )
Treatment of adult roundworms ( Toxocara cati)
Treatment of adult intestinal hookworms ( Ancylostoma tubaeforme).
Dogs :
Treatment of biting lice infestations ( Trichodectes canis )
Treatment of sarcoptic mange (caused by Sarcoptes. scabiei ).
Treatment of adult intestinal roundworms ( Toxocara canis )
5.
CONTRAINDICATIONS
Do not use in animals under 6 weeks of age. Do not use in cats that are suffering from concomitant
disease, or are debilitated and underweight (for size and age).
6.
ADVERSE REACTIONS
Use of the product in cats has on rare occasions been associated with a mild transient alopecia at the
site of application. On very rare occasions transient focal irritation may also be observed. The
alopecia and irritation are normally self-resolving, but symptomatic therapy may be applicable in
some circumstances.
On rare occasions, application of the product may produce a local temporary clumping of the hair at
the application site and/or an occasional appearance of a small quantity of a white powder. This is
normal and will disappear typically within 24 hours of treatment administration and does not affect
either the safety or efficacy of the product.
Exceptionally, as with other macrocyclic lactones, reversible neurological signs have been observed
after use of the product.
It is important to apply the dose as indicated to minimise the quantity that the animal can lick off. If
significant licking does occur, a brief period of hypersalivation may rarely be observed in cats.
Other information
STRONGHOLD has been tested with no other adverse reactions in over 100 different pure and mixed
breeds of dogs including collies, and in mixed breeds and 16 pure breeds of cats.
40
The product was administered at 10 times the recommended dose, and no undesirable effects were
observed. The product was administered at 3 times the recommended dose to cats and dogs infected
with adult heartworms and no undesirable effects were observed. The product was also administered
at 3 times the recommended dose to breeding male and female cats and dogs, including pregnant and
lactating females nursing their litters and at 5 times the recommended dose to ivermectin-sensitive
collies, and no undesirable effects were observed.
In extensive field testing no interactions between the product and routinely used veterinary medicinal
products or medical or surgical procedures were observed.
If you notice any other side effects, please inform your veterinary surgeon.

Flea treatment and prevention (cats and dogs)
Animals older than six weeks of age:
Following administration of the product to the animal, adult fleas and larvae are killed and no viable
eggs are produced. This stops flea reproduction and may aid in the control of existing environmental
flea infestations in areas to which the animal has access.
41
 
For the prevention of flea infestations, the product should be administered to the animal at monthly
intervals throughout the flea season, starting one month before fleas become active. This ensures that
fleas infesting the animal are killed, no viable flea eggs are produced by these fleas, and larvae (found
only in the environment) are also killed. This breaks the flea life cycle and prevents flea infestations.
For use as part of a treatment strategy for flea allergy dermatitis the product should be administered at
monthly intervals.
Treatment of pregnant and lactating animals to prevent flea infestations in puppies and kittens:
Through a reduction in the flea population, monthly treatment of pregnant and lactating animals will
aid prevention of flea infestation in the litter up to seven weeks of age.
Prevention of heartworm disease (cats and dogs)
The product may be administered year-round or at least within one month of the animal’s first
exposure to mosquitoes and monthly thereafter until the end of the mosquito season. The final dose
must be given within one month after the last exposure to mosquitoes. If a dose is missed and a
monthly interval between dosing is exceeded then immediate administration of the product and
resumption of monthly dosing will minimise the opportunity for the development of adult heartworms.
When replacing another heartworm preventive product in a heartworm disease prevention programme,
the first dose of the product must be given within a month of the last dose of the former medication.
Treatment of roundworm infections (cats and dogs)
A single dose of the product should be administered.
Treatment of biting lice (cats and dogs)
A single dose of the product should be administered.
Treatment of ear mites (cats)
A single dose of the product should be administered.
Treatment of ear mites (dogs)
A single dose of the 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.
Treatment of hookworm infections (cats)
A single dose of the product should be administered.
Treatment of sarcoptic mange (dogs)
For complete elimination of the mites, a single dose of the product should be administered for two
consecutive months.
For external use only.
Apply topically to the skin at the base of the neck in front of the shoulder blades.
42
STRONGHOLD should be administered as a single topical application of a unit dose delivering a
minimum of 6 mg/kg selamectin. When concurrent infestations or infections in the same animal are
to be treated with the product, only one topical application of the recommended 6 mg/kg dose should
be administered at any one time. The appropriate length of the treatment period for individual
parasites is specified in section DOSAGE FOR EACH SPECIES.
9.
ADVICE ON CORRECT ADMINISTRATION
