Adipex reduces hunger by stimulating the brain and nerves, which are part of the central nervous system. When the nervous system is stimulated, it causes:

• Heart to beat faster
• Blood pressure to rise
• Feelings of less hungriness

While the effects of Adipex do wear off after a few weeks, it can be a great help in getting a weight loss program going during those first few tough weeks. Most people take it for about 3 to 6 weeks.

Adipex belongs to a group of medications called sympathomimetic amines, which are similar to amphetamines.
