What is Phentermine?

Oral Phentermine Hydrochloride (HCL) is sold for weight loss. It is in the Sympathomimetic family of appetite suppressants (used for the short-term management of exogenous obesity.) When used in conjunction with diet, exercise, and behavior therapy, Phentermine may help you to lose weight while you are learning new ways to eat and to exercise.

Three forms of Phentermine are available:

TABLETS
CAPSULES
RESIN CAPSULES

How does Phentermine work?

Phentermine works by stimulating the hypothalamus gland and affecting certain neurotransmitters to decrease appetite. The hypothalamus is the region of the brain that controls the autonomic nervous system, regulating sleep cycles, body temperature, appetite, etc.

Proper Use of Phentermine

Phentermine should be taken on an empty stomach, once daily, prior to breakfast. If in tablet form, the tablet may be broken or cut in half. Do NOT break, crush, or chew tablets.

As Phentermine may disrupt normal sleep patterns, avoid taking a dose late in the day. If taking more than one dose a day, take the last dose approx. 4-6 hours prior to going to bed.

The following information is specific only to the average doses of Phentermine. The recommended dose of Phentermine may be different for different patients. If your dose is different, do NOT change it unless your doctor tells you to do so.
