Ulesfia Usage

Step 1

  • Cover your face and eyes with a towel and keep your eyes closed tightly.
  • Apply Ulesfia lotion directly to dry scalp and dry hair.
  • Ulesfia lotion must cover your entire scalp and all scalp hair. Have an adult help you apply Ulesfia.

Step 2

  • Massage Ulesfia into your hair and scalp.
  • When your head is completely covered with enough Ulesfia, dripping will happen. Protect your eyes and skin from these drips with your towel.
  • Be sure to apply Ulesfia to the area behind your ears.
  • Be sure to apply Ulesfia to the back of your neck.

If not enough Ulesfia is used, some lice may escape treatment. It is important to use the full amount of Ulesfia prescribed by your healthcare provider.

  • Allow Ulesfia to stay on your hair for 10 minutes. Use a timer or clock.
  • Start timing after you have completely covered your hair and scalp with Ulesfia.

Step 4

  • After 10 minutes, completely rinse Ulesfia from your hair and scalp with water.
  • You or anyone who helps you apply Ulesfia should wash your hands after application.
  • You can shampoo your hair right after the application.
  • A lice comb may be used to remove the dead lice after both applications.

Step 5

One week (7 days) after your first application, repeat the steps above to help get rid of lice that hatched from eggs.

Ulesfia Dosage

Apply the full amount of Ulesfia prescribed by your healthcare provider for each of your 2 applications one week apart. Your doctor will prescribe a specific amount of Ulesfia based on your hair length. Be sure to cover all of your scalp area and hair.

Ulesfia gets rid of lice but does not get rid of lice eggs so a second application is needed one week (7 days) after the first application.

  • Use Ulesfia exactly as prescribed. Your healthcare provider will prescribe the treatment that is right for you. Do not change your treatment unless you talk to your healthcare provider.
  • Use Ulesfia in two applications that are one week apart. Ulesfia Lotion gets rid of lice but does not get rid of lice eggs so a second application is needed one week (7 days) after the first application.
  • Ulesfia coats the lice on your scalp and scalp hair. It is important to use enough Ulesfia to coat completely every single louse and to leave it on your scalp for the full 10 minutes. 
  • Because you need to completely cover all of the lice with Ulesfia, you may need help in applying Ulesfia to your scalp and hair. Make sure that you and anyone who helps you apply Ulesfia reads and understands the instructions for use.
  • Children need adult help in applying Ulesfia.
  • Do not get into eyes. If Ulesfia gets in the eye, flush with water right away.
  • Do not swallow Ulesfia. If swallowed, call your healthcare provider right away.
  • Wash your hands after you apply Ulesfia.

Ulesfia Overdose

If someone swallows Ulesfia, call your local Poison Control Center or seek emergency medical attention right away.

Other Requirements

  • Store Ulesfia in a dry place at room temperature between 68°F to 77°F (20°C to 25°C).
  • Do not freeze Ulesfia.
  • Keep Ulesfia and all medicines out of the reach of children.

To help prevent the spread of lice from one person to another, here are some steps you can take.

  • Avoid head-to-head contact at school, on the playground, in physical education classes, during sports activities, and while playing with other children.
  • Do not share combs, brushes, hats, scarves, bandannas, ribbons, barrettes, hair bands, towels, helmets, or other hair-related personal items with anyone else, whether they have lice or not.
  • Avoid sleepovers and slumber parties during lice outbreaks. Lice can live in bedding, pillows, and carpets that have recently been used by someone with lice.
  • After finishing treatment with lice medicine, check everyone in your family for lice after one week. Be sure to talk to your healthcare provider about treatments for those who have lice.
  • Machine-wash any bedding and clothing used by anyone having lice or thought to have been exposed to lice. Machine wash at high temperatures (150°F) and tumble in a hot dryer for 20 minutes.
