What is Mysimba used for?
Mysimba is used for weight management in adults who are overweight or living with obesity. It is part of a broader treatment plan that includes lifestyle changes.
- Supports weight management in adults

The medicine is not a stand-alone solution. Its role is to support a structured weight-management programme.

Mysimba combines naltrexone and bupropion. The original content describes this as a dual-action approach that affects appetite control and energy expenditure.
- Naltrexone is described as helping to suppress appetite.
- Bupropion is described as helping to reduce cravings and increase energy expenditure.
Because it is a prolonged-release tablet, the medicine is formulated to be absorbed gradually.

If any side effect is worrying, persistent, or severe, a healthcare professional should be contacted for advice.
