Adipex is a weight loss pill generally prescribed for patients who have health issues connected with their obesity. The active ingredient in Adipex is phentermine hydrochloride, which has chemical activity similar to amphetamines. Adipex has been reported to cause changes in the libido, which have been attributed to the drug's central nervous system effects.

Fight or Flight
Adipex reduces the craving for food by stimulating the central nervous system. This stimulation prompts the brain to initiate the “fight or flight,” or acute stress, response in your body. The nervous system prepares the body for action. It releases hormones, constricts the blood vessels and directs blood away from nonessential areas of the body.
Decreased Blood Flow
Decreased blood flow means decreased flow to the pelvic region, leading to changes in the libido. Adipex can decrease sexual response in men and women. Its side effects include inability to achieve orgasm.
Sexual response is a complex human mechanism, and there are many far reaching connections. Dehydration, another a side effect of taking Adipex, interferes with the body’s normal lubrication. Prolonged dehydration also leads to a decrease in the production of sex hormones, which can lead to a decreased sex drive.
Increased libido after taking Adipex has been reported. This may be a psychological effect rather than a biological occurrence. People who lose weight may feel more attractive, leading to an increase in libido.
If Adipex is taken for a prolonged period of time it can be addictive, even if you are under a doctor's care. Higher dosages and more frequent use of the medication increase the risk of experiencing side effects, including changes in sexual response. Discuss any unusual problems or symptoms with your healthcare provider.
