Phentermine is an oral medication used for short-term weight loss and as an appetite suppressant. When used in conjunction with diet, exercise, and behavior therapy, Phentermine may help you lose weight while you are learning new ways to eat and exercise.
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. Phentermine should NOT be used as a substitute for proper diet or exercise. For maximum effects, it must be used in conjunction with a reduced-calorie diet and/or exercise. Any modifications in your diet, activity level, and behavior must be developed and continued long-term in order to continue losing weight and prevent the lost weight from returning.
How long should I take Phentermine?
Phentermine is usually prescribed for short periods of three months, as the effects of Phentermine tend to wear off after some time, while side effects remain.
