Generic Name: reserpine (re SER peen)
What is reserpine?
Reserpine lowers blood pressure by slowing down your nervous system. This allows your blood vessels to relax and dilate (widen), which helps your heart beat more slowly and improves blood flow.
Reserpine is used to treat hypertension (high blood pressure).
Reserpine is also used to treat agitated psychotic conditions such as schizophrenia.
Reserpine may also be used for purposes not listed in this medication guide.
