Phentermine 37.5 mg

Overview

Phentermine 37.5 mg is a prescription weight-loss medication used as a short-term aid in the management of obesity. It is typically prescribed for individuals who are overweight or obese and have not achieved adequate weight loss through diet and exercise alone.

Phentermine acts as an appetite suppressant and belongs to a class of drugs known as sympathomimetic amines, which are similar to amphetamines. It should be used alongside a reduced-calorie diet, exercise, and lifestyle modification program under medical supervision.

How It Works

Phentermine stimulates the release of norepinephrine in the brain, which helps suppress appetite and reduce hunger.
By activating the sympathetic nervous system, it increases energy expenditure and decreases food intake, aiding weight loss when combined with proper diet and exercise.

It works best as part of a comprehensive weight management program supervised by a healthcare provider.
