Descriptions


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).

Spironolactone and hydrochlorothiazide are both diuretic medicines (water pills). They reduce the amount of water in the body by increasing the flow of urine, which helps lower the blood pressure.

This medicine is available only with your doctor's prescription.

This product is available in the following dosage forms:

  • Tablet

Make sure you know how you react to this medicine before you drive, use machines, or do anything else that could be dangerous until you know how this medicine affects you. If you feel dizzy, lie down so you do not faint. Then sit for a few moments before standing to prevent the dizziness from returning.

Check with your doctor right away if you become sick while taking this medicine, especially if you have severe or continuing nausea, vomiting, or diarrhea that does not stop. These conditions may cause you to lose too much water or salt and may lead to low blood pressure. You can also lose water by sweating, so drink plenty of water during exercise or in hot weather.
