What is hydrochlorothiazide and hydralazine (Hydra-Zide)?
Hydrochlorothiazide is a thiazide diuretic (water pill) that helps prevent your body from absorbing too much salt, which can cause fluid retention.
Hydralazine is a vasodilator that works by relaxing the muscles in your blood vessels to help them dilate (widen). This lowers blood pressure and allows blood to flow more easily through your veins and arteries.
Hydrochlorothiazide and hydralazine is usually given after other blood pressure medications have been tried without successful treatment.
Hydrochlorothiazide and hydralazine may also be used for purposes not listed in this medication guide.
