Depression is a serious medical condition, which can lead to suicidal thoughts and behavior. A combined analysis of 9 antidepressants showed an increased risk from 2% to 4% in people under 18. This risk must be balanced with the medical need. Those starting medication should be watched closely for suicidal thoughts, worsening of depression, or unusual changes in behavior. In children and teens, Zoloft is only approved for use in those with obsessive-compulsive disorder.
