Adipex-P is chemically related to amphetamines. It works by suppressing the appetite, and it may also increase the metabolism.
Only very short studies have evaluated the effectiveness of medications like Adipex-P. In these studies, people taking these medications lost more weight than those not taking them, but the difference was small (only a fraction of a pound more per week for the people taking the weight loss medication). Studies also suggest that the effects of these medications for weight loss decrease after the first few weeks.
