Patient/Family Teaching

  • Instruct patient/parent on correct application technique and not to change treatment without consulting health care professional. Use suspension in 1 or 2 treatments that are 1 wk apart. If live lice are seen 7 days after first application, repeat application. Shake bottle well. Cover face and eyes with a towel and keep eyes tightly closed. Use suspension only on dry scalp and dry hair. Completely cover scalp first, then apply outwards towards ends of hair. Use enough suspension to coat completely every single louse. Leave it on scalp for a full 10 min. Continue to keep eyes covered to prevent dripping into eyes. Because all lice must be covered, help with application is advised. After 10 mins, completely rinse suspension from hair and scalp with warm water. Wash hands after application. Hair may be shampooed any time after treatment.
  • Instruct patient to avoid swallowing suspension or getting suspension in eyes. If suspension gets in eyes, flush eyes thoroughly with water.
  • Advise patient/parent that others residing in the home should be examined for lice.
  • Instruct patient/parent on methods of preventing re-infestation. All clothes, including outdoor apparel and household linens, should be machine-washed using very hot water and dried for at least 20 min in a hot dryer. Soak brushes and combs in hot (130° F), soapy water for 5–10 min. Remind patient that brushes and combs should not be shared. Shampoo wigs and hairpieces. Vacuum rugs and upholstered furniture. Wash toys in hot, soapy water. Items that cannot be washed should be sealed in a plastic bag for 2 wks.
  • If patient is a child, instruct parents to notify school nurse or day care center so that classmates and playmates can be checked.
  • Advise female patient to notify health care professional if pregnancy is planned or suspected, or if breastfeeding. Lactating women may choose to pump and discard breast milk for 8 hrs after use to avoid infant ingestion.

Evaluation/Desired Outcomes

  • Absence of lice and nits.
