Aldactone-A Tablet: Uses, Dosage, Side Effects, Precautions and Alternates

Quick overview

Aldactone-A Tablet contains spironolactone, a potassium-sparing diuretic that works by blocking the hormone aldosterone. It is used for high blood pressure, swelling or fluid buildup from heart, liver, or kidney conditions, primary hyperaldosteronism, and low potassium levels. It helps the body remove extra salt and water while holding on to potassium. It should be used exactly as prescribed, with attention to kidney and liver function, potassium intake, and pregnancy status.

What is Aldactone-A Tablet

Aldactone-A is a tablet medicine containing spironolactone. It is a type of water pill (diuretic) that helps your body get rid of extra salt and water without losing too much potassium.

Aldactone-A Tablet uses

• High blood pressure (hypertension)
• Swelling and fluid buildup (edema) from heart failure, liver disease, or kidney problems
• Primary hyperaldosteronism (a condition where the body makes too much of a hormone called aldosterone)
• Low potassium levels (hypokalemia)

Benefits of Aldactone-A Tablet

• Helps lower blood pressure
• Reduces swelling and fluid retention caused by heart, liver, or kidney conditions
• Helps balance potassium levels in the blood
• Can help reduce the need for hospital stays in people with severe heart failure

How Aldactone-A Tablet works

This medicine blocks the hormone aldosterone from working in the kidneys. This causes the kidneys to remove extra salt and water from the body while holding on to potassium, which helps control blood pressure and reduce swelling.

Aldactone-A Tablet dosage

This medicine can be taken with or without food, but take it the same way every time. It is usually taken once a day in the morning, or split into two doses with breakfast and lunch. Try to take your dose at the same time each day. Tablets can be split, cut in half, or crushed if your doctor approves, but should not be chewed and should be swallowed. If you miss a dose, take it as soon as you remember, but if it is almost time for your next dose, skip the missed one — do not take two doses together. Keep taking this medicine even if you feel well, especially for high blood pressure, since it often has no symptoms. Avoid salt substitutes, potassium supplements, and foods very high in potassium such as bananas, prunes, raisins, and orange juice unless your doctor tells you otherwise.
