Hydrochlorothiazide/Spironolactone


Pronunciation: spir-ON-oh-LAK-tone/HYE-droe-KLOR-oh-THYE-a-zide
Generic Name: Spironolactone/Hydrochlorothiazide
Brand Name: Aldactazide

Spironolactone, an ingredient in Hydrochlorothiazide/Spironolactone, has been shown to cause tumors in laboratory animals. Hydrochlorothiazide/Spironolactone should be used for the conditions for which it is indicated. Avoid unnecessary use of Hydrochlorothiazide/Spironolactone.


Hydrochlorothiazide/Spironolactone may not be appropriate for all patients. Tell your doctor if you have never taken any medicine for high blood pressure or for swelling or fluid retention.


Be sure to keep all doctor and lab appointments while you are taking Hydrochlorothiazide/Spironolactone.





Hydrochlorothiazide/Spironolactone is used for:

Treating swelling and fluid retention in patients who have congestive heart failure, cirrhosis of the liver, or a certain kidney problem (nephrotic syndrome) when other treatments are not effective or appropriate. It is also used to treat high blood pressure in patients for whom other treatments are not effective or appropriate. It may also be used for other conditions as determined by your doctor.


Hydrochlorothiazide/Spironolactone is a combination of a potassium-sparing diuretic (spironolactone) and a thiazide diuretic (hydrochlorothiazide). It works by making the kidneys eliminate sodium (salt) and water from the body, which helps to lower blood pressure. The spironolactone component helps minimize potassium loss.


Do NOT use Hydrochlorothiazide/Spironolactone if:


  • you are allergic to any ingredient in Hydrochlorothiazide/Spironolactone, to thiazide diuretics (eg, indapamide), or to any other sulfonamide (eg, sulfamethoxazole)

  • you are unable to urinate, have severe kidney problems, severe liver problems, or high blood potassium levels

  • you are taking another potassium-sparing diuretic (eg, amiloride, triamterene), another aldosterone-blocker (eg, eplerenone), or dofetilide

Contact your doctor or health care provider right away if any of these apply to you.



Before using Hydrochlorothiazide/Spironolactone:


Some medical conditions may interact with Hydrochlorothiazide/Spironolactone. Tell your doctor or pharmacist if you have any medical conditions, especially if any of the following apply to you:


  • if you are pregnant, planning to become pregnant, or are breast-feeding

  • if you are taking any prescription or nonprescription medicine, herbal preparation, or dietary supplement

  • if you have allergies to medicines, foods, or other substances

  • if you have cirrhosis or other liver problems, diabetes, gout, kidney problems (eg, kidney stones), asthma, heart problems (eg, heart failure), menstrual problems, or systemic lupus erythematosus (SLE or lupus)

  • if you have high cholesterol or triglyceride levels, elevated blood acid, low folic acid levels, or electrolyte problems (eg, low blood sodium levels), or are dehydrated

  • if you have a history of high blood potassium levels

  • if you have recently had a certain type of nerve surgery (sympathectomy)

  • if you have never taken medicines for high blood pressure or for swelling or fluid retention

Some MEDICINES MAY INTERACT with Hydrochlorothiazide/Spironolactone. Tell your health care provider if you are taking any other medicines, especially any of the following:


  • Angiotensin-converting enzyme (ACE) inhibitors (eg, enalapril), angiotensin II receptor antagonists (eg, valsartan), cyclosporine, macrolide immunosuppressives (eg, tacrolimus), other aldosterone-blockers (eg, eplerenone), other potassium-sparing diuretics (eg, amiloride, triamterene), potassium supplements, or salt substitutes containing potassium because the risk of high blood potassium levels may be increased

  • Nonsteroidal anti-inflammatory drugs (NSAIDs) (eg, indomethacin) because they may decrease Hydrochlorothiazide/Spironolactone's effectiveness, and the risk of high blood potassium or kidney problems may be increased

  • Corticosteroids (eg, prednisone), corticotrophin (ACTH), or loop diuretics (eg, furosemide) because the risk of low blood potassium levels may be increased

  • Cholestyramine or colestipol because they may decrease Hydrochlorothiazide/Spironolactone's effectiveness

  • Barbiturates (eg, phenobarbital), diazoxide, digoxin, dofetilide, ketanserin, lithium, narcotic pain medicines (eg, codeine), or medicines for high blood pressure because the risk of their side effects may be increased by Hydrochlorothiazide/Spironolactone

  • Insulin or other diabetes medicines (eg, glipizide) because their effectiveness may be decreased by Hydrochlorothiazide/Spironolactone

This may not be a complete list of all interactions that may occur. Ask your health care provider if Hydrochlorothiazide/Spironolactone may interact with other medicines that you take. Check with your health care provider before you start, stop, or change the dose of any medicine.

Untreated angle-closure glaucoma can lead to permanent vision loss. If these eye problems occur, symptoms usually occur within hours to weeks of starting Hydrochlorothiazide/Spironolactone.
