Fleas (pregnant and lactating queens and bitches to prevent flea infestations in kittens and puppies) Through a reduction in the flea population, monthly treatment of pregnant and lactating queens and bitches will aid prevention of infestations in the litter up to seven weeks of age.
For the treatment of adult roundworm infections in dogs and cats, a single dose of Stronghold should be administered. For the treatment of adult hookworm infections in cats, a single dose of Stronghold should be administered.
For the treatment of biting lice infestations in cats and dogs, a single dose of Stronghold should be administered. For the complete elimination of sarcoptic mange mites in dogs, a single dose of Stronghold should be administered for two consecutive months. For the treatment of ear mites in cats, a single dose of Stronghold should be administered.
For ear mites in dogs a single dose of Stronghold 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.
For the prevention of heartworm disease in dogs and cats, Stronghold 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 last dose should be given within one month of the last exposure to mosquitoes.
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 the 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 Stronghold and fingers. 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 Stronghold, only one topical application of the recommended 6 mg/kg dose should be administered at any one time.
For external use only. This product is to be applied to the skin surface only. Do not administer orally or parenterally. 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).
Do not apply when the hair coat is wet. However, shampooing or soaking the animal 2 or more hours after treatment will not reduce the efficacy of Stronghold. 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 allow treated animals to bathe in water courses until at least two hours after treatment.
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 Stronghold or until the hair coat is dry.
For ear mite treatment, do not apply directly to the ear canal. Use of Stronghold in cats has occasionally been associated with a mild, transient hair loss at the site of application. In a small proportion of these cases, transient focal irritation may also be observed. The hair loss and irritation are normally self-resolving, but symptomatic therapy may be applicable in some circumstances.
On rare occasions, application of Stronghold may produce a local temporary clumping of the hair at the application site and/or the appearance of a small quantity of a white powder. This is normal and will disappear typically within 24 hours of administration and does not affect either the safety of efficacy of Stronghold. Exceptionally, as with other macrocyclic lactones, reversible neurological signs have been observed after use of the product.
It is important to apply the dose to the correct site 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. 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.
People with sensitive skin or known allergy to products of this type should handle Stronghold with caution. Do not smoke, eat or drink while handling Stronghold.
Any unused product or waste material should be disposed of in accordance with local requirements. Selamectin may adversely affect fish or certain water-borne organisms on which they feed. Containers and residual contents should be disposed of along with collected domestic refuse to avoid contamination of any water courses.
Keep out of the reach and sight of children. Do not store above 30°C. Store in the unopened foil package in a dry place. Highly Flammable - Keep away from heat, sparks, open flame or other sources of ignition.
Following administration of Stronghold, adult fleas on the animal are killed and no viable eggs are produced and larvae (found only in the environment) are also killed. This stops flea reproduction, breaks the flea life cycle and may aid in the control of existing environmental flea infestations in areas to which the animal has access.
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. Stronghold is not effective against adult Dirofilaria immitis.
If a dose is missed for heartworm prevention and a monthly interval between dosing is exceeded then immediate administration of the product and resumption of monthly dosing will minimise the opportunity of a development of adult heartworms. When replacing another heartworm preventative product in a heartworm disease prevention programme, the first dose of Stronghold must be given within a month of the last dose of the former medication.
Stronghold was administered at 10 times the recommended dose to cats and dogs and no undesirable effects were observed. Stronghold 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 no undesirable effects were observed. Stronghold was also administered at 5 times the recommended dose to ivermectin-sensitive collies, and no undesirable effects were observed.
Stronghold was also administered at 3 times the recommended dose to cats and dogs infected with adult heartworms and no undesirable effects were observed. In extensive field testing, no interactions between Stronghold and routinely used veterinary medicinal products or medical or surgical procedures were observed.
