Bupropion / naltrexone
"I am a 40yo female and took this drug for 3 mos for undesired weight gain as a side effect of another medication. I  lost only 3 lbs and the entire time it was up/down lose 3 lbs gain 3 lbs. I stopped taking this medicine because it does not work. I exercise daily and watch my diet and the results are no different than if you don't do anything differently. Side effects at first were nausea and headache but they subsided. Maybe this drug works if the reason for your weight gain is excess caloric intake and/or lack of exercise but it doesn't help you lose weight when you're already trying to and nothing is working. Also the $ is conflicting. My first prescription was the price it should've been if you have insurance thereafter it was 3x cost."
