About

Mysimba is a prescription weight-loss treatment that works by reducing your appetite. It is available to those with a BMI of 30 or more, or to those with a BMI of 27 and over and have medical complications exacerbated by their weight. This medication should be taken in combination with a low-calorie diet and regular exercise to ensure treatment success.

How it works

Mysimba contains two active ingredients, 8 mg of naltrexone and 90 mg of bupropion. The combination of the two alters the way the brain interprets hunger by reducing your appetite and increasing your energy expenditure. This means you can maintain a low-calorie diet without feeling cravings or hunger pains and the food you do eat is burnt off more easily during exercise. This is why it’s important to use this medication alongside a healthy diet and exercise plan.

Who can take Mysimba

You can only be prescribed this medication if you are 18 or over and have a BMI of 30 and above, or 27 and above if you have other medical conditions exacerbated by your weight such as diabetes, high blood pressure or high cholesterol.

You should not take this medication if you are pregnant or breastfeeding, or are allergic to any of the ingredients.This medication is also not recommended for those over the age of 75.
