What is phentermine?
Phentermine (Adipex-P®) is a prescription drug used for weight loss. This medication serves as an appetite suppressant. Phentermine works by aiding the release chemicals in the brain that control appetite. Phentermine should be used for only short periods (for a few weeks) as part of a physician-guided weight loss program, which includes a reduced calorie diet and exercise. Your doctor should decide if phentermine is right for you based on your weight, height, and any health problems you may have. In combination with a reduced calorie diet, the use of phentermine has been shown to produce additional weight loss. The safety and effectiveness of using phentermine with other drugs for weight loss has not been proven.
Expected weight loss with phentermine
Weight loss is greatest during the first few weeks of therapy but typically levels off with continued use. Weight loss can vary from person to person and phentermine does not work for everyone. Phentermine is typically taken in the morning or 10-14 hours before bedtime to minimize trouble sleeping.
