This medication is used to treat head lice, tiny insects that infest and irritate your scalp. Permethrin is also used to help avoid infestation in people who have close contact with someone who has head lice. It belongs to a class of drugs known as pyrethrins. Permethrin works by paralyzing and killing lice and their eggs (nits).
Apply this medication as soon as possible after it is prescribed. When treating head lice, apply this medication to the hair and scalp only. First wash hair with your regular shampoo, but do not use conditioner. Thoroughly rinse the shampoo out with water, and towel-dry hair. Shake this medication well before using. Cover your eyes with a towel while applying this medication. Completely cover the hair and scalp with the medicine (especially behind the ears and on the hairline at the neck). Avoid getting permethrin in your nose, ears, mouth, vagina, or eyes. If the medicine gets in any of these areas, flush with plenty of water. Do not use more medication than prescribed. Leave the medication on your hair for 10 minutes or as directed by your doctor, then rinse with warm water. Towel-dry your hair and comb out any tangles. A single permethrin treatment can help prevent lice from coming back for 14 days. If eyebrows or eyelashes are infested, do not apply this medication to those areas without first consulting your doctor.
Head lice lay small white eggs (nits) at the base of hair close to the scalp, especially on the hairline at the back of the neck and behind the ears. After treatment with this medication, the infected person should be checked by another person for lice and nits using a magnifying glass and bright light. To remove nits, use the special comb provided, and follow the instructions on the package. After combing, re-check the entire head every day for nits you might have missed. Remove any nits by combing, by hand using a disposable glove, or by cutting them out. If live lice are seen 7 days or more after treatment, a second treatment with permethrin or another drug may be needed.
Inform your doctor if your condition persists or worsens.
Scalp irritation, including itching, swelling, or redness may occur with head lice and temporarily worsen after treatment with permethrin. Mild burning, stinging, tingling, or numbness may also occur. If any of these effects persist or worsen, tell your doctor or pharmacist promptly.

One application is usually all that is needed. To avoid giving lice to another person or getting them again, all head wear, scarves, coats, and bed linens should be machine-washed with hot water and dried in a dryer (at high setting) for at least 20 minutes, dry cleaned, sealed in a plastic bag for 2 weeks, or sprayed with a disinfectant that kills lice. Brushes or combs should be soaked in hot water (hotter than 130 degrees F/54 degrees C) for 10 minutes, soaked in alcohol for 1 hour, or thrown away. Furniture and floors should be thoroughly vacuumed.
People who are in close contact with the infected person, such as members of the same household, should also be checked for lice and nits. Treatment may be considered to prevent infestation even if live lice are not found on them.
