Understanding Lice and Scabies -- Treatment
What Is the Treatment for Lice?
To get rid of head lice, the most common treatment is to kill the adults with a pediculocide and to clear out the nits with a special fine-toothed comb.
Pyrethrins are a common treatment that is available over the counter. Brand names include Rid, Triple X, Pronto, A-200. For best results, follow the directions exactly. Repeat treatment in nine to 10 days to kill any new lice that may have hatched since the first treatment.
Permethrin lotion 1% (also known as Nix) is another over the counter product which also only kills lice, but not eggs, and will require repeat treatment in nine to 10 days.
Malathion lotion 0.5% (also known as Ovide) is a prescription medication that is approved for head lice and can kill some eggs. Directions and precautions for use must be strictly followed.
Lindane shampoo 1% is approved for lice treatment, but shouldn't be used as first line treatment. If used improperly, especially in young children, it can attack and damage the brain and other parts of the nervous system.
A treatment for lice approved by the FDA in early 2011 called spinosad (Natroba) is topical and applied to the scalp. It is not approved for use on children under age 4.
Another treatment is a topical lotion called Sklice. A comb is not required with Sklice and one treatment may be all that's needed. The active ingredient is ivermectin, a powerful parasite killer. Sklice can be used in children as young as 6 months.
For those who prefer to avoid the use of insecticides, try a "combing only" technique. Wash the hair with ordinary shampoo and conditioner, and leave wet. With a fine-toothed comb, stroke slowly outward from the roots through one lock of hair at a time. Lice will land on the back of the comb, get caught between the teeth, or fall off. Space at least 30 strokes over the head. Repeat every three days. Because newborn lice do not lay eggs for the first week, all the lice should disappear after about two weeks of combing.
