Almost a quarter of Americans over the age of 18 are now medicated for one or more of these conditions.

More specifically, according to data provided to The Times by Express Scripts, a pharmacy benefits manager, prescriptions across three categories of mental health medications — depression, anxiety and A.D.H.D. — have all risen since the pandemic began. But they have done so unevenly, telling a different story for each age group and each class of medication.

Antidepressants continue to be the most commonly prescribed of these medications in the United States, and their use has become only more widespread since the pandemic began, with an 8.7 percent rate of increase from 2019 to 2021, compared with 7.9 percent from 2017 to 2019, according to Express Scripts.

IQVIA, a global health technology and clinical research firm, found that in 2021, a total of 337,054,544 prescriptions were written for antidepressants in the United States through the course of the year, representing a steady annual increase since 2017, when that number had been 313,665,918.

But for some age groups, that change has been more pronounced. Since 2017, there has been a 41 percent increase in antidepressant use for the teenagers included in the Express Scripts data (which consists of roughly 19 million people.) For this same 13- to 19-year-old bracket, in the first two years of the pandemic, there was a 17.3 percent change in anxiety medications. It had been a 9.3 percent rate of change between 2017 and 2019.

One 13-year-old rising eighth grader in Colorado currently takes the antidepressant Paxil and the stimulant Adderall. (She also takes melatonin, a nonprescription supplement, to help her sleep.)
