Stronghold Spot On for Dogs & Cats

Stronghold Spot On for Dogs & Cats

Stronghold provides one of the most complete parasite treatments available in one easy spot-on application. The contents of one pipette are emptied onto the skin of the back of the neck once a month. The active ingredient is absorbed through the skin and for 1 month it will kill fleas, lice, worms and mites wherever they are, either inside, or on the surface of, the body. In areas where heartworm is found, Stronghold prevents this too, which is important for dogs and cats traveling to Europe on the Pet Travel Scheme.

Fleas (cats and dogs)

For the treatment and prevention of flea infestations in dogs and cats, Stronghold should be administered at monthly intervals throughout the flea season, starting one month before fleas become active.

For use as part of a treatment strategy for flea allergy dermatitis, Stronghold should be administered at monthly intervals.

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.

Roundworm (cats and dogs older than six weeks of age)

For the treatment of adult roundworm infections in dogs and cats, a single dose of Stronghold should be administered.

Hookworm (cats older than six weeks of age)

For the treatment of adult hookworm infections in cats, a single dose of Stronghold should be administered.

Biting Lice (cats and dogs)

For the treatment of biting lice infestations in cats and dogs, a single dose of Stronghold should be administered.

Sarcoptic Mange (dogs)

For the complete elimination of sarcoptic mange mites in dogs, a single dose of Stronghold should be administered for two consecutive months.

Ear mites (cats)

For the treatment of ear mites in cats, a single dose of Stronghold should be administered.

Ear mites (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.

Heartworm (cats and dogs)

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.

Dosage and administration

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.

Contra-indications, warnings, etc

For animal treatment only.

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,including seizures, 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.

Operator warnings

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.

Environmental warning

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.

Pharmaceutical precautions

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.

Legal category

POM-V

Packaging Quantities

Stronghold is available in packs of three tubes (all tube sizes), six tubes (all tube sizes except Stronghold 15 mg) and 15 tubes (Stronghold 15 mg only).

Further information

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.

Ask Your Own Question

Pregnant cat

Katherine Turner

Can I use stronghold on my heavily pregnant cat?

John Cousins
  • Veterinary Surgeon at VioVet

Stronghold is safe to give during pregnancy or lactation. There is a general guide that all medication should be avoided if possible during the first third of pregnancy. It should however be perfectly safe, and a good idea, to use Stronghold in a heavily pregnant cat.

Can you use stronghold 45 mg on a dog?

22nd Apr 2014
Sophie Cain

Can stronghold 45 mg for cats be used on a dog. If not, why not?

John Cousins
  • Veterinary Surgeon at VioVet

Licensed medicines are strictly controlled and it is against the law for anyone other than the vet to prescribe Stronghold. If the prescribing vet considers using a medicine in some way differently from its legal authorisation, then he can do so and it is up to him to justify his decision afterwards if something goes wrong. Having said that, I expect that most vets would consider it perfectly OK to use the Cat Stronghold on a dog if it was of suitable weight, age etc.

Flea treatment in dogs

10th Aug 2013

How soon after application will the irritation stop.

John Cousins
  • Veterinary Surgeon at VioVet

This normally takes a few days. However it depends on how many fleas are present in the environment, how sensitised the dog has become to flea saliva(injected when they bite), and whether or not the irritation is caused or complicated by other things. All fleas on the dog should die, but more will jump on for a while. They too will die, but if there are lots living in the environment, it will take a while for them all to die. For this reason, it is often recommended to use a household flea spray for carpets and bedding etc as well. All fleas will go in time without, but it takes longer. Sometimes the dog's skin can have a mild, secondary bacterial infection which prolongs irritation. This can be treated as well if needs be, but you vet will have checked for this. If the irritation is persisting longer than you think is reasonable, it is best to return to your vet for advice. There will be a reason, though it is very unlikely to be the Stronghold not killing fleas, as it is generally found to be extremely effective.
