Weight loss tablets



Mysimba is used as an aid to people needing to lose weight. The prolonged release tablets contain a combination of naltrexone hydrochloride and bupropion hydrochloride, which reduces the appetite and changes the taste of food.

What is Mysimba?

Mysimba is a weight loss treatment solution for anyone over the age of 18 who has a body mass index (BMI) of over 30 (which indicates obesity). If you have a BMI over 27 and suffer from co-morbidities such as type 2 diabetes or controlled hypertension then Mysimba could be the right weight loss medication for you to take.

A combination of naltrexone hydrochloride and bupropion hydrochloride, Mysimba has been developed to help people who want to lose weight by helping the brain to regulate your appetite and change the feelings you may have when eating food.

What are the key benefits of Mysimba?

Mysimba has been shown to help people lose an average of 5% of their total body weight after 16 weeks, compared to 1% without using the medicine, when taken with a reduced calorie diet and increased exercise.

Mysimba can also help you to reduce triglycerides and LDL (bad) cholesterol. Diabetics taking Mysimba also noted improvements in their blood sugar control.

Mysimba is a tablet which can be taken with or without food. For the first week you take 1 tablet each morning. During the second week you take one tablet in the morning and 1 tablet in the evening. During the third week the dose is 2 tablets in the morning and 1 tablet in the evening. In the fourth week you should be taking 2 tablets both in the morning and in the evening.
