DEAR DOCTOR K: I heard about a new drug that can help people lose weight. I'm overweight. Should I give it a try?
DEAR READER: You're likely referring to Contrave, a drug the FDA approved in September of 2014 to help people lose weight along with a reduced-calorie diet and exercise. Contrave combines two drugs, naltrexone and bupropion. These drugs are already approved for other uses. Naltrexone is used to help kick alcohol and narcotic addiction. Bupropion is used to treat depression and seasonal affective disorder. Many people also take bupropion to stop smoking. Neither naltrexone nor bupropion by itself has been approved for weight loss.
