Phentermine was designed to work as a treatment for obese patients and can control your weight. Since it was first released on the market in 1959, it has slowly become a common drug pill for overweight patients, but was specifically made for the obese. However, for Phentermine to work effectively the patient must attempt to lead a much healthier lifestyle during and after the treatment.

Taking Phentermine regularly in conjunction with diet therapy with a nutritionist or doctor, and an exercise program supervised by a professional will lead to the best weight loss results. Once Phentermine treatment is completed, which is usually after 8-12 weeks, the nutritious diet and exercise must be continued if the patient wants to continue to lose weight or at least maintain their weight loss.
