Do not use this medicine on your child unless approved by your doctor.

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

To prevent spread of lice to other people, good health habits are also required. These include the following:

  • Dry-clean or wash all clothing, bedding, and personal items (including washcloths, towels, hats, scarves, combs, brushes, hairpieces, and wigs) in hot, soapy water.
  • Clean the house or room by thorough vacuuming.

Skin irritation may occur while using the medicine. If it occurs, wash scalp and hair right away and check with your doctor.

Call your doctor right away if you have burns (including second-degree burns) and stinging sensation after using this medicine.

Breathing in even small amounts of carbamate- or organophosphate-type insecticides or pesticides (e.g., carbaryl [Sevin®], demeton [Systox®], diazinon, malathion, parathion, or ronnel [Trolene®]) may add to the effects of this medicine. Farmers, gardeners, residents of communities undergoing insecticide or pesticide spraying or dusting, workers in plants manufacturing such products, or other persons exposed to such poisons should protect themselves by wearing a mask over the nose and mouth, changing clothes frequently, and washing hands often while using this medicine.

Do not use this medicine for a hair or scalp problem that has not been checked by your doctor.
