Medical Weight Loss: FDA Approved Prescription Medications

The word “diet” typically conjures up thoughts of starvation, bland foods and an overall unpleasant experience that may or may not result in weight loss.  Since sticking to the diet is such an ordeal, many dieters reward themselves by satisfying their appetite with their favorite foods once the weight is lost and, you guessed it, the weight comes right back.  The cycle can easily be avoided through the use of an effective appetite suppressant.

Appetite suppressants work in two ways.  They lessen the user’s cravings for food, so that the dieter is less likely to snack in between meals.  They also help the dieter to feel full sooner during a meal, so the user is less likely to eat as much food per meal.  Overall, appetite suppressants work to lower an individual’s caloric intake while keeping him satisfied.

INDICATIONS:  Management of exogenous obesity as an adjunct in a regimen of weight reduction based on caloric restriction in patients with an initial BMI (body mass index) of greater than 25 and PBF (percent body fat) of greater than 28% in females and 20% in males who have not responded to appropriate weight reducing regimen  (diet and/or exercise) alone.  To be used in conjunction with supplements, diet and exercise.

Phentermine/phendimetrazine/diethylpropion are stimulants that are similar to an amphetamine.  These are appetite suppressants which affect the central nervous system. 

Phentermine/phendimetrazine/diethylpropion are used together with diet and exercise to treat obesity (overweight) in people with risk factors such as high blood pressure, high cholesterol, or diabetes.  They may also be used for other purposes not listed in this medication guide.
