Some side effects related to the use of mental-health medications represent special risks for young people. For example, a rare but dangerous kind of liver damage associated with the concomitant use of several different medications is much more common in children than in adults. Doctors are now given highlighted warnings to be alert for suicidal behavior that can occur in young people (adults, too) soon after they are started on antidepressants—perhaps because the medicine can energize a patient and stimulate action before the drug acts to decrease the depression and impulse to suicide.
