What is Didrex
Didrex
is a sympathomimetic amine, which is similar to an amphetamine.
It is also known as an "anorectic" or "anorexigenic"
drug. Didrex stimulates your central nervous system (nerves
and brain), which increases your heart rate and blood pressure
and decreases your appetite.
Didrex
is used as a short-term supplement to diet and exercise in
the treatment of obesity.
Didrex
may also be used for purposes other than those listed in this
medication guide.
