Spironolactone and hydrochlorothiazide combination is used to treat high blood pressure (hypertension). It may also be used to treat water retention (edema) in patients with congestive heart failure, liver cirrhosis, or a kidney disorder called nephrotic syndrome.
Spironolactone helps prevent your body from absorbing too much salt and keeps your potassium levels from getting too low. It can be used to prevent or treat hypokalemia (low potassium levels in the blood).
This medicine is available only with your doctor's prescription.
In addition to the use of this medicine, treatment for your high blood pressure may include weight control and changes in the types of foods you eat, especially foods high in sodium (salt) and potassium. Your doctor will tell you which of these are most important for you. You should check with your doctor before changing your diet.

You may have to take high blood pressure medicine for the rest of your life. If high blood pressure is not treated, it can cause serious problems such as heart failure, blood vessel disease, stroke, or kidney disease.
