More than 25% of Americans who take antidepressant medicines haven't actually been diagnosed with the conditions like depression and anxiety disorders that require them to take these medicines.

A psychologist and currently a medical student at the University of Manitoba in Canada, Jina Pagura said, "We cannot be sure that the risks and side effects of antidepressants are worth the benefit of taking them for people who do not meet criteria for major depression. Although an antidepressant might help with these issues, the problems may also go away on their own with time, or might be more amenable to counseling or psychotherapy." Prescription of antidepressants has been an ongoing issue since a long time, with some doctors arguing that they are not always helpful, while some believing that they are absolutely essential in treating depression.
