Antidepressants are among the most prescribed medications in the United States. This is, in part, because the number of people diagnosed with depression and anxiety has been on the rise, and prescriptions jumped sharply among some age groups during the pandemic.

About 80 percent of antidepressants are prescribed by primary care doctors who have not had extensive training in managing mental illness.
Dr. Paul Nestadt, an associate professor of psychiatry at the Johns Hopkins School of Medicine, said patients tell him, “‘You know, Doc, I’ve tried everything.’” But often, he said, “they never got to a good dose, or they were only on it for a week or two.”
