You may have to provide several samples to your health care provider for examination. Since scratching of the anal area is common, samples taken from under the fingernails may also contain eggs. Eggs are rarely found during lab examinations of stool or urine. At night, the adult worms can sometimes be seen directly in bedclothes or around the anal area. You should consult your health care provider before treating a suspected case of pinworm.
Treatment involves a two-dose course.
The second dose should be given 2 weeks after the first. The infected person should be treated with the same two-dose treatment. Close family contacts should also be treated. If the infection occurs again, you should search for the source of the infection. Playmates, schoolmates, close contacts outside the house, and household members should be considered.
