Mysimba is a prescription-only weight-loss medication containing naltrexone and bupropion. You take 1-2 tablets once or twice a day up to a maximum of 4 tablets per day. Bupropion helps to reduce your appetite so that you do not feel as hungry and are satisfied with less food. Naltrexone is thought to curb your food cravings which reduces your desire to eat.

Mysimba is approved to help you lose weight in conjunction with an active lifestyle and a calorie-controlled balanced diet.

Mysimba should be taken alongside a calorie-controlled diet and exercise to help you lose weight. Exercise and a balanced diet will help you to maintain a healthy weight even when you stop taking your medication.
