PHENTERMINE HYDROCHLORIDE- phentermine hydrochloride tablet
Phentermine hydrochloride tablets USP are 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 greater than or equal to 30 kg/m
2 , or greater than or equal to 27 kg/m
2 in the presence of other risk factors (e.g., controlled 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 limited usefulness of agents of this class, including phentermine, [see Clinical Pharmacology ( 12.1, 12.2) ] should be measured against possible risk factors inherent in their use such as those described below.
Dosage should be individualized to obtain an adequate response with the lowest effective dose.
The usual adult dose is one tablet as prescribed by the physician, administered in the morning, with or without food. Phentermine is not recommended for use in pediatric patients less than or equal to 16 years of age.
Late evening medication should be avoided because of the possibility of resulting insomnia.
With dry hands, gently remove the phentermine hydrochloride tablet from the bottle. Immediately place the phentermine hydrochloride tablet on top of the tongue where it will dissolve, then swallow with or without water.
