Benzphetamine, sold under the brand name Didrex among others, is an amphetamine-type stimulant and appetite suppressant used short-term for weight loss along with a doctor-approved, reduced-calorie diet, exercise, and behavioral program. It is prescribed for obesity to people who have been unable to lose weight through exercise and dieting alone. It is a prodrug of dextromethamphetamine and dextroamphetamine.[4][5][6]

It primarily promotes weight loss through reduced appetite, but also slightly increases metabolism.[citation needed]
