Spironolactone 100 mg Tablet: Complete Guide on Uses, Benefits, Side Effects, Dosage & Price
Sep 12, 2025
Introduction
Spironolactone 100 mg, available under the brand name S LACTONE 100 by Steris Healthcare Pvt Ltd, is a widely prescribed medication belonging to the class of potassium-sparing diuretics and aldosterone antagonists. It is an essential drug in the management of hypertension, heart failure, fluid retention (edema), hyperaldosteronism, and certain hormonal disorders. Unlike many other diuretics, Spironolactone retains potassium while removing excess sodium and water from the body, making it a safer choice in long-term therapy. Its additional hormonal effects also make it useful in treating polycystic ovary syndrome (PCOS), acne, and hirsutism in women. At Steris Healthcare Pvt Ltd, we manufacture S LACTONE 100 (Spironolactone 100 mg tablet) under WHO-GMP-certified facilities, ensuring quality, efficacy, and affordability for patients across India.
