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. . Some studies suggest pyrethrins can affect cognitive development in children. More research is needed. Brand names include Rid, Triple X, Pronto, A-200. For best results, follow the directions exactly.
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.
Pubic lice can be treated with over-the counter medications containing pyrethrins or permethrin lotion 1%. Your sexual partners will also have to be treated. Crabs are also sometimes found on eyelashes or eyebrows. A nit comb or fingernails may be used if there are only a few live nits on them. Otherwise a special prescription eye ointment may be prescribed.
To treat body lice, wash the entire body with soap and water. If this is not effective, you may have to use pediculocide preparation -- either over-the-counter or prescription. As with a head lice infestation, you'll have to wash all clothing, towels, and bedding in hot water and dry in a hot dryer.
What Is the Treatment for Scabies?
Scabicides that kill mites -- and some also kill eggs -- are available by prescription only. Permethrin cream 5% (also known as Elimite) is a common treatment that kills mites and eggs. It is approved for use in adults and children at least two months old.
Lindane lotion is approved for use as scabies treatment, but should not be used as first-line therapy. If used improperly, it can attack and damage the brain and other parts of the nervous system.
