ADIPEX-P® (phentermine hydrochloride) is indicated as a short-term (a few weeks) adjunct in a regimen of weight reduction based on exercise, behavioral modification and caloric restriction in the management of exogenous obesity for patients with an initial body mass index ≥ 30 kg/m2, or ≥ 27 kg/m2 in the presence of other risk factors (e.g., hypertension, diabetes, hyperlipidemia).
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 x 0.0254 = meters.

The usual adult dose is one capsule or tablet (37.5 mg) daily, administered before breakfast or 1-2 hours after breakfast. For tablets, the dosage may be adjusted to the patient's need. For some patients 1/2 tablet (18.75 mg) daily may be adequate, while in some cases it may be desirable to give 1/2 tablet (18.75 mg) two times a day.
Late evening medication should be avoided because of the possibility of resulting insomnia.
