Spironolactone has caused tumors in laboratory animals. Talk to your doctor about the risks and benefits of using this medicine for your condition.
This medication should not be used when you first begin your treatment. You should take this medication only after the appropriate dosages of spironolactone and hydrochlorothiazide are individually established by your doctor.
The combination of spironolactone and hydrochlorothiazide is used to treat high blood pressure. This medication is also used to treat patients with edema (fluid retention) caused by various conditions, including heart, liver, or kidney disease. Spironolactone is in a class of medications called aldosterone receptor antagonists. It causes the kidneys to eliminate unneeded water and sodium from the body into the urine, but reduces the loss of potassium from the body. Hydrochlorothiazide is in a class of medications called diuretics (''water pills''). It works by causing the kidneys to get rid of unneeded water and salt from the body into the urine.
The combination of spironolactone and hydrochlorothiazide comes as a tablet to take by mouth. It usually is taken once or twice a day. If you are to take it once a day, take it in the morning; if you are to take it twice a day, take it in the morning and in the late afternoon to avoid going to the bathroom during the night. Follow the directions on your prescription label carefully, and ask your doctor or pharmacist to explain any part you do not understand. Take spironolactone and hydrochlorothiazide exactly as directed. Do not take more or less of it or take it more often than prescribed by your doctor.
This medication controls high blood pressure and edema, but does not cure these conditions. Continue to take spironolactone and hydrochlorothiazide even if you feel well. Do not stop taking spironolactone and hydrochlorothiazide without talking to your doctor.
This medicine is sometimes prescribed for other uses; ask your doctor or pharmacist for more information.
Follow your doctor's directions for a low-salt or low-sodium diet and daily exercise program. Avoid potassium-containing salt substitutes. Limit your intake of potassium-rich foods (e.g., bananas, prunes, raisins, and orange juice). Ask your doctor for advice on how much of these foods you may have.
Take the missed dose as soon as you remember it. However, if it is almost time for the next dose, skip the missed dose and continue your regular dosing schedule. Do not take a double dose to make up for a missed one.
