How does Mysimba work?

Mysimba features a combination of two active ingredients, namely bupropion hydrochloride and naltrexone hydrochloride. Bupropion helps you feel less hungry by making you satisfied with less food. Naltrexone in the Mysimba weight loss tablets, helps curb food cravings reducing your desire to eat. 

The two ingredients of Mysimba help patients curb their appetite and control the size of the food portions. Using Mysimba tablets also boosts energy, so they stay active and follow a healthy and controlled diet to lessen their body weight.
