What is Mysimba® and how does it work?

What is Mysimba®?

Mysimba® is a prescription-only, weight-loss medicine, for adults over 18 years of age. It contains two active substances:

• naltrexone hydrochloride; and
• bupropion hydrochloride.

You have been prescribed Mysimba® to help you manage your weight; together with a reduced calorie diet, and physical exercise.

Body Mass Index (BMI)
Your body mass index (BMI) is used to find out if you need to lose weight. For most adults, a BMI of:³

• 25 to 29.9 means you’re overweight;
• 30 to 39.9 means you’re obese; and
• 40 or above means you’re severely obese.

The body mass index is calculated as your body weight in kilograms (kg) divided by your height squared in metres (m2).
You often see this formula written as BMI = weight in kg/height m²

Mysimba® is believed to reduce hunger and help control cravings by working on two areas of your brain. These areas are involved in controlling how much:

• food you eat; and
• energy you use.
