What Medications Are Commonly Used in Medical Weight Loss Programs?

By stimulating the release of neurotransmitters like norepinephrine in the brain, phentermine helps reduce hunger and cravings. It is typically prescribed for a few weeks to jumpstart weight loss efforts, and is often used in conjunction with a reduced-calorie diet and exercise program. Phentermine is generally recommended for individuals who are obese or significantly overweight and have not had success with lifestyle changes alone.
