Mild pinworm infection, or an infection with no symptoms, may not need treatment. If treatment is needed, your doctor may prescribe medication to all members of your household to prevent infection and reinfection. The most common prescription anti-parasite medications for pinworms are:

  • Mebendazole
  • Albendazole (Albenza)

You may have mild gastrointestinal side effects during the course of treatment, and you often need to take at least two doses to get rid of the pinworms completely.

Methods to help prevent the spread of pinworm eggs or to prevent reinfection include:

  • Wash in the morning. Because pinworms lay their eggs at night, washing the anal area in the morning can help reduce the number of pinworm eggs on your body. Showering may help avoid possible recontamination in bath water.
  • Change underwear and bed linen daily. This helps remove eggs.
  • Launder in hot water. Wash bedsheets, nightclothes, underwear, washcloths and towels in hot water to help kill pinworm eggs.
  • Don't scratch. Avoid scratching the anal area. Trim your child's fingernails so there's less space for eggs to collect. Discourage nail biting.
  • Clean toilet seats daily. This helps remove eggs.
  • Wash your hands. To reduce your risk of getting or spreading an infection, wash your hands thoroughly after a bowel movement or changing a diaper and before eating.
