How should I use this medicine?

Do not get this medicine in your eyes. If you do, rinse out with plenty of cool tap water. Thoroughly rub the medicine into your hair and scalp. Make sure you get behind the ears and on the back of the neck. Leave on your hair for 10 minutes. Then rinse thoroughly with water. Dry with a clean towel. When your hair is dry, comb it with a fine toothed comb to remove any leftover nits (eggs) or nit shells. If you still have lice after one week, see your doctor or health care professional. You may need a second treatment. If you are applying this medicine to another person, wear plastic or disposable gloves to protect yourself from infestation.

What should I watch for while using this medicine?

This medicine is used as a single application treatment. If live lice are observed 7 or more days after initial application, a second treatment may be needed.

Head lice can be spread from one person to another by direct contact with clothing, hats, scarves, bedding, towels, washcloths, hairbrushes, and combs. All members of your household should be examined for head lice and should receive treatment if they are found to be infected. If you have any questions about this, check with your doctor or health care professional.

To prevent reinfection or spreading of the infection, the following steps should be taken: Machine wash all clothing, bedding, towels, and washcloths in very hot water and dry them using the hot cycle of a dryer for at least 20 minutes. Clothing or bedding that cannot be washed should be dry cleaned or sealed in an airtight plastic bag for 2 weeks. Shampoo any wigs or hairpieces. You should also wash all hairbrushes and combs in very hot soapy water (above 130 degrees F) for 5 to 10 minutes. Do not share your hairbrushes or combs with other people. Wash all toys in very hot water (above 130 degrees F) for 5 to 10 minutes or seal in an airtight plastic bag for 2 weeks. Also, clean the house or room by vacuuming furniture, rugs, and floors.
