Labeled uses (from FDA prescribing information)
Benzphetamine Hydrochloride Tablets are indicated in the management of exogenous obesity as a short term (a few weeks) adjunct in a regimen of weight reduction based on caloric restriction in patients with an initial body mass index (BMI) of 30 kg/m2 or higher who have not responded to appropriate weight reducing regimen (diet and/or exercise) alone. Below is a chart of Body Mass Index (BMI) based on various heights and weights. BMI is calculated by taking the patient's weight, in kilograms (kg), divided by the patient's height, in meters (m), squared. Metric conversions are as follows: pounds ÷2.2 = kg; inches × 0.0254 = meters. The limited usefulness of agents of this class (See CLINICAL PHARMACOLOGY ) should be weighed against possible risks inherent in their use such as those described below. BODY MASS INDEX (BMI), kg/m2 Weight (pounds) | Height (feet, inches) | 5'0" | 5'3" | 5'6" | 5'9" | 6'0" | 6'3" | 140 | 27 | 25 | 23 | 21 | 19 | 18 | 150 | 29 | 27 | 24 | 22 | 20 | 19 | 160 | 31 | 28 | 26 | 24 | 22 | 20 | 170 | 33 | 30 | 28 | 25 | 23 | 21 | 180 | 35 | 32 | 29 | 27 | 25 | 23 | 190 | 37 | 34 | 31 | 28 | 26 | 24 | 200 | 39 | …
