Question 1

What is the treatment of lice and scabies infestations and what tips would you give the patient or patient's family?

Accepted Answer

The preferred drug for lice and scabies infestation is permethrin. This drug is considered the safest agent, especially for infants and children. Pyrethrin is a related product which is also widely used to kill lice and their eggs on contact.
Tips: Apply the permethrin cream to the entire skin surface and allow it to remain for eight to 14 hours before bathing. Itching may continue for several weeks as the dead mites are removed from the skin. A newer entry to the market, dimethicone, is applied to dry hair, massaged in until hair is completely wet, and left on for 30 minutes, and then the hair is combed with a lice comb. The solution is allowed to dry on the hair for at least eight hours and then the hair is washed. All scabicides and pediculicides must be used strictly as directed because excessive use has the potential to cause serious systemic effects and skin irritation. While applying the drugs for the treatment of lice or mites, care must be taken to avoid the mouth, open skin lesions, or eyes because exposure the drug will cause severe irritation. Lice lay eggs, which are called nits. Fine-toothed nit combs are useful in removing nits after the lice have been killed. Patients should comb the infested area after the hair has been dried. To ensure that drug therapy is effective, patients should inspect hair shafts daily for at least one week after treatment. Because nits may be present in bedding and other upholstery material, all material coming in close contact with the patient should be washed in hot water or treated with the appropriate agent. Advise patients to inform family members, sexual partners, school personnel, and any other persons with whom close contact has occurred about skin infestations. Clothes, bed linens, and personal items should be treated properly to avoid reinfestation. Ensure that patients using pediculicides repeat the treatment in seven to 10 days to increase its effectiveness.
