Head Lice: FDA Approves New Treatment

Good news for parents, teachers, pediatricians, and others engaged in the ongoing battle against lice: The Food and Drug Administration (FDA) just approved a new treatment for head lice in children age four and older. Called Natroba, it’s a liquid that is rubbed into the hair and allowed to sit for 10 minutes before being rinsed off. Natroba is a useful addition to the anti-lice arsenal, since some head lice have become resistant to permethrin and pyrethrins, the active ingredients in over-the-counter anti-lice products such as Nix and Rid.

Head lice are tiny insects that go by the big name Pediculus humanus capitis. They thrive in the warm tangle of human hair, feeding off blood in the scalp and breeding with abandon. A female lays eggs called nits that she attaches to strands of hair. Nits hatch after about eight days, become adults in another week or so, feed for awhile, then begin to make more lice.

What To Do

First off, here’s what not to do: Don’t shave your or your child’s head, or coat it with petroleum jelly or mayonnaise or anything else designed to “suffocate” the parasite. You’ll probably end up with greasy, smelly, lice-infested hair.

Current guidelines from the American Academy of Pediatrics call for the use of an over-the-counter product containing permethrin or pyrethrins as a first salvo against head lice. Shampoos and rinses made with these substances are generally effective. Most treatments for head lice need to be used twice, seven to 10 days apart, along with combing wet hair with a fine-toothed nit comb. Some lice are resistant to pyrethrin and permethrin. Stronger prescription drugs, such as malathion and lindane, also work but aren’t as safe for humans. That’s where Natroba comes in. Read more »

Eat To Save Your Life: Another Half-True Diet Book
