Adipex is a brand name for the medication phentermine, which is a prescription weight loss medication. It is primarily used as a short-term adjunct therapy to a reduced-calorie diet and increased physical activity for the management of obesity.
Phentermine works by suppressing appetite and increasing energy expenditure, which can help people with obesity to eat less and burn more calories. It is believed to work by increasing the release of neurotransmitters such as norepinephrine, which stimulate the sympathetic nervous system and reduce hunger.
