Permethrin, a pyrethroid, is active against a broad range of pests including lice, ticks, fleas, mites, and other arthropods. It acts on the nerve cell membrane to disrupt the sodium channel current by which the polarization of the membrane is regulated. Delayed repolarization and paralysis of the pests are the consequences of this disturbance.
Permethrin is rapidly metabolized by ester hydrolysis to inactive metabolites which are excreted primarily in the urine. Although the amount of permethrin absorbed after a single application of the 5% cream has not been determined precisely, data from studies with 14C-labeled permethrin and absorption studies of the cream applied to patients with moderate to severe scabies indicate it is 2% or less of the amount applied.

For external use only. Avoid contact with the eyes and mucous membranes. If contact occurs, wash the area thoroughly with water.
Usually 30 grams of permethrin cream is sufficient for an average adult.
Scabies rarely infest the scalp of adults, although the hairline, neck, temple, and forehead may be infested in geriatric patients and infants.
One application is generally curative. A second treatment of permethrin lotion may be given for patients that present with live lice 7 days after the initial treatment.
Patients may experience persistent pruritus after treatment for scabies. Demonstrable living mites after 14 days indicate retreatment is necessary.
Safety and efficacy in children under the age of 2 months have not been established.
