Do not share this medication with others.

To avoid spreading lice to other people or getting them again, all recently worn/used (within 2 days before treatment) head wear, scarves, clothing, towels, pillow cases, and bed linens should be machine-washed with hot water and dried in a dryer (at high setting) for at least 20 minutes. For items that cannot be washed, the items may instead be dry cleaned, sealed in a plastic bag for 2 weeks, or sprayed with a disinfectant that kills lice. Brushes, combs, and hair clips 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 family members in the same household) should also be checked for lice and nits. Treatment may be considered to prevent lice in these people.
