Apply the shampoo exactly according to the instructions, taking care not to get it in the child's eyes or mouth. - If necessary, apply a vinegar rinse to loosen the nits, then comb the child's hair with a fine-tooth comb until all the nits have been removed. - Clean combs and brushes with the shampoo, launder pillowcases, and have caps or hats washed or dry-cleaned. PRECAUTIONS - If one member of the family has head lice, it is often necessary to treat the rest of the family as well (except infants and pregnant women). - The ingredient gamma benzene hexachloride prescribed in shampoo form for head lice is poisonous if swallowed or absorbed through the skin. It can also harm the eyes. Use it exactly as directed. Do not repeat the application more than twice, at the stated intervals. Do not leave the shampoo within reach of the child. - Consult your doctor if head lice are accompanied by infected sores on the scalp or enlarged lymph nodes at the base of the skull. Head lice are tiny parasites (less than one-eighth inch long). They are grayish-white, almost transparent, six-legged creatures that live exclusively on humans--not on pets. The lice pass easily from one person to another. Head lice live on or close to the scalp, where they bite and suck blood. Their eggs, which are called nits, are milk-white and about the size of a flake of dandruff. During the past few years, infestation with head lice has become common among school-age children. SIGNS AND SYMPTOMS Head lice cause itching of the scalp and sometimes a red, scaly rash on the back of the neck at the hairline. Scratching may cause sores on the scalp. The lymph nodes at the base of the skull may be enlarged. Unless hundreds are present, it is difficult to see lice in a child's hair. Look for the small but easily visible nits attached to the shafts of the hairs. Although nits are about the same color and size as flakes of dandruff, they can be easily distinguished from dandruff: flakes of dandruff can be blown or brushed away; nits can be removed with the fingernails only with difficulty. HOME CARE Apply the recommended amount of a 1-percent gamma benzene hexachloride shampoo (which your doctor will prescribe) to your child's dry hair. Work it into a lather, and leave it on for four minutes. Then rinse well with water. Be very careful not to get this shampoo into the child's eyes or mouth. After rinsing, comb the child's hair with a fine-tooth comb to remove the nits. If necessary, use a vinegar rinse to loosen the nits before combing. Repeat the shampoo and combing only once, four to seven days later. This procedure kills both the lice and the eggs. Clean combs and hairbrushes with the gamma benzene hexachloride shampoo. To kill stray lice, clean hats and pillowcases by washing and ironing or by dry cleaning. Lice can also be killed by using one of several special shampoos containing pyrethrins. These shampoos are available without a prescription. Always follow the package instructions carefully. PRECAUTIONS Gamma benzene hexachloride is lindane, a white powder used chiefly as an insecticide. It is poisonous if swallowed or absorbed through the skin. It can also harm the eyes. Do not let it come in contact with the eyes or mouth. Do not leave it within your child's reach. Do not apply it more than twice. If one person has head lice, all family members except infants and pregnant women should be treated with the shampoo. If the lice are accompanied by infected sores on the scalp or enlarged, tender lymph nodes at the base of the skull, consult your doctor. MEDICAL TREATMENT If there are infected sores or infected lymph nodes, your doctor may culture the sores and prescribe an oral antibiotic for five to ten days. RELATED TOPICS: Glands, swollen; Scabies
