Permethrin is a synthetic pyrethroid active against lice, ticks, mites, and fleas. It acts on neural cellmembranes, delaying repolarization and causing paralysis. The compound has no reported adverse properties, is heat and light stable, has 70% to 80% ovicidal activity, and leaves an active residue on the scalp. Permethrin is 26 times less toxic than lindane and 3 times less toxic than pyrethrins. A 1% permethrin cream rinse (Nix) preparation with a single application was determined to be more effective than treatment with RID. Permethrin-treated military uniforms are effective against human body lice. Apply the cream rinse for 10 minutes and rinse off with water. Localized pruritus may be reported with use of this product.
