It is best to take the worming medicine at night before going to bed. Before going to bed at night, the body will be in a state of fasting, and the parasites will be hungry at this time. If you take worming medicine at night before going to bed, the concentration of the medicine in the intestine will be relatively high because there is no food in the stomach to neutralize it, and the deworming effect will be more obvious. The parasites are not particularly active at night when they are sleeping. When the medication acts on the parasites, the parasites will be less active, so the pain and discomfort in the abdomen will be less severe and the impact on the human spirit will be avoided. It is best to go to the hospital for a routine stool examination after using worming medication to understand the treatment effect of eliminating worms, and for patients whose parasites are not completely cleared, they can take medication again after an interval.
