To avoid fainting do not stand quickly and avoid standing or exercising for long periods of time. This combination product must not be the first treatment used to control high blood pressure.
USES: Guanethidine helps to widen arteries and veins so blood flows better. Hydrochlorothiazide (HCTZ) is a diuretic "water pill", that rids the body of excess fluid. This combination medication is used to treat hypertension (high blood pressure).
