Overview

Spironolactone is an aldosterone antagonist and potassium-sparing diuretic. It may be ordered for Blood Pressure management, heart failure support, edema or fluid retention management, low potassium support, or hyperaldosteronism depending on provider order, patient diagnosis, medication profile, discharge instructions, and pharmacy label. Common brand names may include Aldactone and Carospir.

For home health nurses, Spironolactone indication and home health teaching often focuses on Blood Pressure monitoring if ordered, edema or swelling monitoring, heart failure symptom reporting, weight monitoring if ordered, medication compliance, dizziness precautions, orthostatic safety, fall prevention, potassium safety awareness, lab appointment reminders when ordered, hydration or fluid instruction reminders per provider order, medication list review, and when to notify PCP or call 911.

DailyMed labeling for Aldactone lists Spironolactone as an aldosterone antagonist indicated for NYHA Class III-IV heart failure with reduced ejection fraction, add-on therapy for Hypertension, edema related to cirrhosis or nephrotic syndrome, and primary hyperaldosteronism. MedlinePlus lists Spironolactone for certain patients with hyperaldosteronism, low potassium levels, heart failure, edema, and high Blood Pressure.

Spironolactone may help manage Blood Pressure, fluid-related symptoms, or provider-ordered potassium-related concerns, but it does not cure the underlying condition. Patient-specific use, precautions, monitoring, diet, fluid instructions, labs, and administration instructions must always follow provider order, medication profile, pharmacy label, discharge instructions, plan of care, and agency policy.

Common Indications for Spironolactone

Common indications may include:

• Hypertension
• Blood Pressure management
• Heart failure support, when ordered
• Edema or fluid retention management, when ordered
• Edema related to liver disease or kidney disease, when ordered
• Hypokalemia support, when ordered
• Primary hyperaldosteronism, when ordered
• Provider-ordered potassium-sparing diuretic therapy

DailyMed labeling for Aldactone includes heart failure, Hypertension as add-on therapy, edema related to cirrhosis or nephrotic syndrome, and primary hyperaldosteronism. The label also includes warnings related to hyperkalemia, hypotension, worsening renal function, and electrolyte/metabolic abnormalities.

MedlinePlus notes that Spironolactone helps the kidneys remove unneeded water and sodium through urine while reducing potassium loss. It also notes that Spironolactone tablets and suspension release medication differently and should not be substituted unless the doctor says to do so.

Drug classification is not the same as patient-specific indication. For example, Spironolactone may be classified as an aldosterone antagonist or potassium-sparing diuretic, but the patient-specific indication may be Hypertension, heart failure support, edema, hypokalemia support, hyperaldosteronism, or another provider-ordered reason.

Heart failure	CHF / heart failure support
CHF with fluid retention	CHF / fluid management
Edema	Edema / fluid retention
Liver disease with edema	Cirrhosis / edema management
Nephrotic syndrome with edema	Nephrotic edema management
Hypokalemia support, when ordered	Hypokalemia support
Primary hyperaldosteronism	Hyperaldosteronism
Potassium-sparing diuretic therapy	K-sparing diuretic therapy
Ordered diuretic therapy	Diuretic therapy monitoring

Home Health Teaching Focus

For home health nursing, Spironolactone teaching often focuses on medication compliance, Blood Pressure monitoring if ordered, swelling or edema monitoring, heart failure symptom reporting, weight monitoring if ordered, dizziness and orthostatic precautions, fall prevention, potassium safety awareness, medication list review, and provider reporting.

Patients may need reinforcement if they have a new Spironolactone order, recent Hospital stay, Hypertension, heart failure, edema, fluid retention, kidney-related concerns, potassium-related precautions, abnormal Blood Pressure readings, dizziness, weakness, fall risk, weight changes if monitoring weight, medication confusion, refill problems, or PCG involvement.

Patient Teaching Points for Spironolactone

Basic teaching may include:

• Take Spironolactone exactly as ordered by PCP/provider.
• Do not stop, hold, skip, take extra, or change medication unless instructed by PCP/provider.
• Monitor Blood Pressure, weight, swelling, or fluid symptoms only if ordered or instructed.
• Report dizziness, lightheadedness, fainting, weakness, worsening swelling, shortness of breath, sudden weight gain if weight monitoring is ordered, or symptoms that continue or worsen.
• Use fall precautions and rise slowly if dizzy, weak, or unsteady.
• Ask PCP or pharmacist before using potassium supplements, salt substitutes, NSAIDs, or new over-the-counter medications.
• Follow provider instructions for diet, potassium, sodium, and fluid intake.
• Keep ordered lab appointments if labs are ordered by PCP/provider.
• Call 911 or seek emergency help for chest pain, severe shortness of breath, fainting, sudden confusion, severe weakness, trouble breathing, or symptoms that feel life-threatening.
• Keep updated medication list available for PCP, pharmacy, home health agency, and Hospital visits.
