Lice - Medications

Medicine choices continued...

If these OTC or prescription medicines aren't working, your doctor may prescribe a different medicine to help get rid of lice. These include ivermectin (Sklice or Stromectol), permethrin 5% (Elimite), and spinosad (Natroba). In rare cases, lindane may be prescribed. But lindane is falling out of favor because of the potential for serious nervous system side effects. The American Academy of Pediatrics no longer recommends lindane as a treatment for head lice.

Antihistamines (both prescription and nonprescription) can help relieve the itching that often occurs with lice. These medicines may cause drowsiness. Don't give antihistamines to your child unless you've checked with the doctor first.

If there is a serious skin infection, antibiotics may be needed.

What to think about

It is not necessary to remove lice eggs camera.gif from hair after treatment with topical medicines, but some people may wish to remove them for cosmetic reasons.

Most products used to treat lice may cause side effects if they are not used properly. Never use a product more than two times (with less than 7 days between uses) without first consulting a doctor.

There is some concern that lice are becoming resistant to (can no longer be killed by) permethrin or other medicine used to treat lice infestations. It is also possible that lice may persist after treatment because the medicine was not used properly or because the person was reinfected by someone else who was still infected with lice.

Wet combing is an option for infants who can't use lice medicines.
