Method of application
Selamectin is administered externally as a topical/spot-on solution.
Dosage and administration
Selamectin is available in separate canine and feline formulas, with the specific dosage based on the animal’s body weight. It is important that you weigh your pet prior to treatment and only use the product intended for their type and size.
For the prevention of heartworm disease, Selamectin should be applied every month. The first application should within 30 days of the animal’s initial exposure to mosquitoes and the final application within 30 days of their last exposure.
For the treatment and control of flea infestations, Selamectin should be applied once a month.
For the treatment of ear mites, biting lice, sarcoptic mange (in dogs) and roundworms (in cats), a single dose of Selamectin should be applied.
Do not apply to wet hair and do not allow the treated animal to get wet for 2 hours after treatment.
Follow the package directions carefully to ensure maximum product efficacy, and to ensure the product is applied in a position that the animal cannot lick it off.
