Precautions

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.

Other Comments

Concomitant treatment of individuals in the household is recommended to avoid reinfestation. Thorough cleaning of all clothing and bedding is required once treatment has begun.

For proper head lice management, nits should be removed with a nit comb.
