Reserpine lowers blood pressure by decreasing the levels of certain chemicals in your
blood. This allows your blood vessels (veins and arteries) to relax and your heart to beat more
slowly and easily.
Hydrochlorothiazide is a thiazide diuretic (water pill). It helps to lower your blood
pressure and decrease edema (swelling) by increasing the amount of salt and water you lose in
your urine.
Together, hydrochlorothiazide and reserpine are used to treat high blood pressure
(hypertension).
Hydrochlorothiazide and reserpine may also be used for purposes other than those listed
in this medication guide.
