Meridia Oral

Uses
This medication is used along with a low-calorie diet to help people with obesity lose weight. Reducing excess weight helps to prevent or control complications such as heart disease, diabetes, and joint pain. Sibutramine works by affecting the area in your brain that controls hunger, providing you with a sense of fullness and satisfaction.
