Selafort in the form of a 6% solution contains selamectin as the active ingredient at a concentration of 60 mg/ml, as well as excipients: isopropyl alcohol, butylhydroxytoluene, and dimethyl sulfoxide. Selafort is used in dogs and cats by a single application to dry, intact skin using pipettes of the appropriate volume. Before use, remove the pipette from the blister and hold it in an upright position, pressing the cap to pierce the tip of the pipette. Then remove the cap, part the fur at the base of the neck between the shoulder blades, and squeeze the entire contents of the pipette directly onto the animal’s skin. The dose of the product (pipette volume) is selected based on the species and body weight of the animal.
