Why am I using Duromine? What is it used for?
For those who are overweight, the anorectic medication Duromine may be helpful as a short-term supplement to behavioural modification, physical activity, and calorie restriction. A Body Mass Index (BMI) of 30 or over is widely recognized as an indication of obesity. People with a body mass index (BMI) of 25 to 29.9 who are overweight and at an increased risk of morbidity may also begin taking Duromine. A doctor should rule out any underlying organic secondary causes of obesity before giving the medicine.
