title: Comparative study of permethrin 1% creme rinse and lindane shampoo for the treatment of head lice.
abstract: The efficacy and safety of permethrin 1% creme rinse and lindane shampoo were compared for the treatment of head lice (Pediculus humanus var. capitis). A total of 1040 patients in the Nezahualcoyotl community of Mexico City representing 296 family groups were enrolled and randomized to treatment, with one patient in each family designated as the index patient. Among index patients 98% treated with permethrin and 76% treated with lindane were louse-free 2 weeks after treatment (P less than 0.001). Comparable results were found with nonindex patients as well. Mild dermal reactions, such as pruritus or erythema, occurred in 1.2% of permethrin-treated patients and 2.6% of lindane-treated patients. There were no reports of central nervous system adverse effects or conjunctivitis.
