This medicine is used as a single application treatment. If live lice are observed 7 or more days after initial application, a second treatment may be needed.

Head lice can be spread from one person to another by direct contact with clothing, hats, scarves, bedding, towels, washcloths, hairbrushes, and combs. All members of your household should be examined for head lice and should receive treatment if they are found to be infected. If you have any questions about this, check with your doctor or health care professional.

To prevent reinfection or spreading of the infection, the following steps should be taken: Machine wash all clothing, bedding, towels, and washcloths in very hot water and dry them using the hot cycle of a dryer for at least 20 minutes. Clothing or bedding that cannot be washed should be dry cleaned or sealed in an airtight plastic bag for 2 weeks. Shampoo any wigs or hairpieces. You should also wash all hairbrushes and combs in very hot soapy water (above 130 degrees F) for 5 to 10 minutes. Do not share your hairbrushes or combs with other people. Wash all toys in very hot water (above 130 degrees F) for 5 to 10 minutes or seal in an airtight plastic bag for 2 weeks. Also, clean the house or room by vacuuming furniture, rugs, and floors.

Keep out of the reach of children and pets.
Store at room temperature between 20 and 25 degrees C (68 and 77 degrees F). Get rid of any unused medicine after the expiration date.
To get rid of medicines that are no longer needed or have expired:

-Take the medicine to a medicine take-back program. Check with your pharmacy or law enforcement to find a location.
-If you cannot return the medicine, check the label or package insert to see if the medicine should be thrown out in the garbage or flushed down the toilet. If you are not sure, ask your health care provider. If it is safe to put it in the trash, empty the medicine out of the container. Mix the medicine with cat litter, dirt, coffee grounds, or other unwanted substance. Seal the mixture in a bag or container. Put it in the trash.
