Head Lice and Body Lice

Alternate Names : Pediculosis

What are the treatments for the disease?

Head lice are treated with shampoos containing permethrin, pyrethrin, or malathion. Nits are removed by combing the hair with a fine-tooth comb or by pulling them out one by one. Clothing should be washed in hot water that is at least 130 degrees Fahrenheit, and then dried in a hot dryer.

Carpets and upholstered furniture should be vacuumed. Combs and brushes should be soaked for an hour in a solution containing anti-lice shampoo. Items that can't be washed, such as hats, coats, and scarves, should be placed in an airtight plastic bag for three weeks.

What are the side effects of the treatments?

Resistance to head lice treatment is increasing. People need to make sure that all the lice have been killed. Shampoos containing permethrin, pyrethrin, or malathion can cause allergic reactions and rashes. It is important to use the shampoo only as directed. If a person uses the medication too many times, it can be toxic and build up in the blood system.

What happens after treatment for the disease?

After treatment, lice and nits should be gone. The healthcare provider should be contacted if any of the following conditions apply:

How is the disease monitored?

To monitor for lice, a person can recheck the hair shafts for nits. A healthcare provider should be consulted if itching or redness persists after home treatment. Any other new or worsening symptoms should also be reported to the healthcare provider.
