How Aldactone 25 Tablet Works

Spironolactone is a potassium-sparing diuretic and aldosterone antagonist. It blocks aldosterone receptors in the kidney, increasing sodium and water excretion while conserving potassium, thereby reducing fluid overload and blood pressure.

Take exactly as prescribed by your doctor. Usually taken orally once daily or in divided doses; take with food to improve absorption and reduce stomach upset. Take at the same time each day; avoid potassium supplements/salt substitutes unless advised.

Always follow your doctor's prescription. Do not self-medicate.
