What Is Mysimba - Slimming Pills for Weight Loss

Mysimba is a weight loss medicine which contains the active ingredients naltrexone and bupropion. When combined with a low-calorie diet and physical exercise, Mysimba can help you shed unhealthy weight.

According to the NHS, approximately 29% of adults in England are obese and more than a third of the population is overweight.

Classification of whether a person is overweight or obese is defined by their body mass index (BMI).

A BMI of 25 - 30 is overweight, while a BMI greater than 30 is obese.

You can work out your BMI using the NHS Online BMI Calculator.


How does Mysimba work?

How Mysimba UK works is not yet fully understood. According to European Medicine Agency, the two active substances, naltrexone and bupropion, act on the parts of the brain that control food intake and energy balance, as well as reducing the effect of the part of the brain that controls the pleasure associated with eating food.

So far, studies have indicated that Mysimba can reduce body weight by at least 5% over the course of 28 to 56 weeks when taken alongside a healthy diet and regular exercise.

How diet and exercise affect Mysimba

While taking any weight loss treatment, it is essential to eat a healthy, balanced and nutritious diet low in saturated fat.

Regular exercise is also key to weight loss goals. Taking up a sport or any recreational activity which requires physical exertion, such as running or dancing, can help immensely.

You should consider keeping a food diary to track your eating habits and exercise regime. This can help you and your doctor to identify areas of your lifestyle you need to improve. For instance, you could be eating too much of a specific food group or not exercising enough.

It's best to speak to our online prescriber or a nutritionist for advice on dieting and exercising.

What should I do if I forget to take Mysimba?

Do not take more Mysimba to make up for the missed dose.

What should I do if I take too much Mysimba?

If you take more Mysimba than you should, contact your doctor or go straight to your nearest A&E department.

Taking more Mysbima than is recommended can increase your risk of experiencing severe side effects, such as seizures.
