How should I use Ulesfia Lotion?
Use Ulesfia Lotion exactly as prescribed. Your health care provider will prescribe the treatment that is right for you. Do not change your treatment unless you talk to your health care provider. Use Ulesfia Lotion in 2 treatments that are 1 week apart. Ulesfia Lotion gets rid of lice, but does not get rid of lice eggs, so a second treatment is needed 1 week (7 days) after the first treatment.
