Natroba

This medication is used to treat head lice, tiny insects that infest and irritate your scalp. Head lice lay small white eggs (nits) at the roots of hair close to the scalp, especially on the hairline at the back of the neck and behind the ears. Spinosad works by paralyzing and killing lice and their eggs.

This medication should not be used on infants younger than 6 months due to the increased risk for serious side effects.

Read the Patient Information Leaflet and Patient Instructions for Use if available from your pharmacist before you start using spinosad and each time you get a refill. If you have any questions, ask your doctor or pharmacist.

This medication is for external use only. Shake the bottle well just before using. Apply this medication to scalp hair and scalp only. Use this medication when your hair is dry. Do not wet your hair before applying. Cover your face and eyes with a towel and keep your eyes closed tightly while applying this medication and during the time it remains on your scalp and hair. Avoid getting spinosad in your eyes. If the medication gets in or near the eye, flush with plenty of water right away. Since you should keep your eyes closed during application, you may need to have another person help you apply this medication. Children will need an adult to apply this medication for them.

Completely cover the scalp with spinosad first, and then apply outward toward the ends of the hair. If you do not use enough spinosad, some lice may escape treatment. It is important to use enough medication to cover your entire scalp and scalp hair. Leave the medication on your hair for 10 minutes. Use a timer or clock and start timing after you have completely covered your hair and scalp with medication. After 10 minutes, rinse thoroughly with warm water. You or anyone who helps you apply this medication should wash hands after application. You may shampoo your hair any time after treatment.

After treatment with this medication, you may use a fine-tooth comb or a special comb for removing treated lice and nits. However, combing is not required. If you see live lice 7 days or more after treatment, a second treatment should be given. Do not repeat treatment more than once unless otherwise directed by your doctor.

Tell your doctor if your condition persists or worsens.

Skin or eye irritation/redness may 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, machine-wash all head wear, clothing, bed linens, and towels with hot water, then dry in a dryer at high setting for at least 20 minutes. Personal articles such as pillows or stuffed animals that cannot be washed should be dry cleaned, sealed in a plastic bag for at least 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 at least 10 minutes. 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. Be sure to talk with your doctor about treatment for those who have lice.
