Combination products such as Zestoretic are usually not prescribed until therapy is already under way.
Hydrochlorothiazide, a diuretic, prompts your body to produce and eliminate more urine, which helps in lowering blood pressure.
It combines an ACE inhibitor drug with a diuretic.
Lisinopril, the ACE inhibitor, works by limiting production of a substance that promotes salt and water retention in your body.
Since blood pressure declines gradually, it may be several weeks before you get the full benefit of Zestoretic and you must continue taking it even if you are feeling well.
You must take Zestoretic regularly for it to be effective.
Zestoretic does not cure high blood pressure it merely keeps it under control.
Zestoretic is prescribed in the treatment of high blood pressure.
