Do not miss a dose, and do not take double doses. Intestinal worms may die slowly. Removal from the digestive tract may take up to 3 days after treatment. Laxatives are not needed. Because pinworm infestations are easily passed from person to person, your doctor may want to treat all family members at the same time.
Good hygiene is essential to avoid spreading or reinfestation.
Change undergarments, bed linens, nightclothes, and towels daily, and wash them in very hot water. Disinfect toilets daily. Do not shake clothing because the eggs are very light and can be spread in the air. Extreme cleanliness is required to eliminate this infection. Temporary abdominal pain and diarrhea have been reported in cases of massive infections and expulsion of worms.
