Group Health researchers have found that bupropion (marketed as Wellbutrin) is the only antidepressant that tends to be linked to long-term modest weight loss.
Previously, Group Health researchers showed a two-way street between depression and body weight: People with depression are more likely to be overweight, and vice versa. These researchers also found that most antidepressant medications have been linked to weight gain.
Prior research on antidepressants and weight change was limited to one year or shorter. But many people take antidepressants--the most commonly prescribed medications in the United States--for longer than a year. So for up to two years the new study followed more than 5,000 Group Health patients who started taking an antidepressant. TheJournal of Clinical Medicine published it: "Long-Term Weight Change after Initiating Second-Generation Antidepressants."
"Our study suggests that bupropion is the best initial choice of antidepressant for the vast majority of Americans who have depression and are overweight or obese," said study leader David Arterburn, MD, MPH. He's a senior investigator at Group Health Research Institute (GHRI), a Group Health physician, and an affiliate associate professor in the University of Washington (UW) School of Medicine's Department of Medicine. But in some cases, an overweight or obese patient has reasons why bupropion is not for them--like a history of seizure disorder--and it would be better for them to choose a different treatment option.
