What should I watch for while using this medicine?
Lice infections can cause itching and irritation. This medicine may cause more itching for a short time after use. This does not mean that the medicine did not work.

Treat everyone who is infected. For cases of pubic lice, sexual partners should be treated at the same time to prevent reinfection.
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 4 weeks. Shampoo any wigs or hairpieces. You should also wash all hairbrushes and combs in very hot soapy water (above 130 F) for 5 to 10 minutes. Do not share your hairbrushes or combs with other people.
