  • PINWORM CHECKS: Check your child for pinworms. * Examine the area around the anus, using a flashlight. * Look for a ¼-inch (6 mm), white, threadlike worm that moves. * Do this a few hours after your child goes to bed. Check him 2 nights in a row. Also, check him first thing in the morning for 2 days.
  • SCOTCH TAPE TEST: * If no adult pinworm is seen, call your doctor's office. Ask for instructions on doing a Scotch-tape test for pinworm eggs. You can also use the technique below: * Take a piece of clear Scotch tape (with the sticky side down). Touch it to the skin on both sides of the anus. Do this in the morning soon after your child has awakened. Also, do this before any bath or shower. * Put the sticky tape side that touched the skin on a slide. If you don't have a slide, put it on a second piece of tape. * Do it 2 mornings in a row. * Bring the 2 samples in to be looked at under a microscope.
  • STEROID CREAM: * For the itching, wash the skin around the anus with warm water. * For severe itch, use 1% hydrocortisone cream 2 times per day. Use for 1 or 2 days. No prescription is needed.
  • CALL YOUR DOCTOR IF: * Pinworm is seen * Skin around the anus gets red or tender * Anal itching lasts more than 1 week * Your child becomes worse 
  • LOW RISK: * Your child has had contact with a child with pinworms, but no symptoms now. Your child probably won't get them. This is especially likely if over a month has passed. * If contact is within the last month, your child may get pinworms. This risk is small. * Pinworms are harmless. They are never present very long without being seen or causing anal itching.
  • SCOTCH TAPE TEST: * If you're still worried, call your doctor's office. Ask for instructions on doing a Scotch tape test. This can be done to look for pinworm eggs. * Do this about 1 month after contact. * Reason: The swallowed egg will not become an adult pinworm for 3 or 4 weeks.

  • WASH HANDS: * Have your child scrub the hands and fingernails well before each meal. Also, wash the hands well after each use of the toilet. * Keep the fingernails cut short, because eggs can collect here. * Help your child give up thumb sucking and nail biting.
  • SHOWER: * Each morning give your child a shower. * Always rinse the anal area. * Do this for 3 days after taking the pinworm medicine.
  • VACUUM: * Vacuum or wet-mop your child's bedroom once a week. * Any eggs left on the floor can still infect others for 1 or 2 weeks.
  • WASH CLOTHES: * Wash clothes and bedding at a hot temperature. This will kill any eggs left in them.

  • PINWORM MEDICINE: * If a pinworm was seen, your child's doctor will suggest a special pinworm medicine. Take as directed. * Give a repeat dose of the pinworm medicine in 2 weeks. Reason: To prevent the pinworms from coming back. * The repeat dose is needed because eggs can live for 1 to 2 weeks. Temperature and humidity levels also affect how long the eggs can stay alive.
  • TREATING CLOSE CONTACTS: * There is a slight risk that Pinworms may spread to others. * Treat family members only if they have symptoms. * If another child sleeps with the infected child, they also should be treated. * If any of your child's friends have symptoms, be sure to tell their parents.
