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.

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.
==Mechanism of Action== Benzphetamine promotes weight loss by reducing appetite and slightly increasing metabolism. It is the parent compound of clobenzorex, the latter of which is not subject to the Federal Analogue Act, nor scheduled per the Controlled Substances Act of 1970.
