The Full Story

PHENTERMINE

Phentermine is a prescription medication used short-term along with a doctor-approved, reduced-calorie diet, exercise, and behavior change program for weight loss.

Function

Phentermine is classified as an anorexiant and a sympathomimetic medication, meaning it stimulates the body's sympathetic nervous system to decrease appetite.

Expectations

Phentermine users can expect to lose between 5-10% of their body weight over 8 weeks, with common side effects including dry mouth, insomnia, dizziness, and elevated heart rate and blood pressure.
