For the 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. Stronghold is also 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 for up to seven weeks of age.
For use 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.
For the treatment of ear mites (Otodectes cynotis).

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.

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.

Method and route of administration
Spot-on use.
Remove the Stronghold pipette from its protective package. Holding the pipette 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 pipette directly to the skin without massaging. Squeeze the pipette firmly to empty the contents in one spot. Avoid contact between Stronghold and fingers.

Contra-indications, warnings, etc
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).
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 Stronghold.
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.
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. On the day of treatment, children must not handle treated animals and the animals should not be permitted to sleep with their owners, especially children. Used tubes should be disposed of immediately and not left within the sight or reach of children.
Use of Stronghold in cats has on rare occasions been associated with a mild, transient hair loss at the site of application. On very rare occasions 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 in cats and dogs, 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.
Very rarely, as with other macrocyclic lactones, reversible neurological signs, including seizures, have been observed after use of Stronghold.
The frequency of adverse reactions is defined using the following convention:
- very common (more than 1 in 10 animals displaying adverse reactions during the course of one treatment)
- common (more than 1 but less than 10 animals in 100 animals)
- uncommon (more than 1 but less than 10 animals in 1,000 animals)
- rare (more than 1 but less than 10 animals in 10,000 animals)
- very rare (less than 1 animal in 10,000 animals, including isolated reports).
