Treatment
The first line of treatment is usually an over-the-counter lotion or shampoo containing 1% permethrin (Nix). Stronger prescription only remedies include malathion (Ovide) or lindane. All of these medications must be used exactly as directed. The nits must be removed from the hair by combing the hair with a specially made comb, dish soap may help loosen the glue of the nits and hasten removal. The clothes and bedding must be washed in hot water and soap as well. Consult a doctor before treating children less than 6 months of age or anyone weighing less than 100 pounds. Retreatment may be necessary in one week.
