Spironolactone is a medication primarily used to treat conditions like high blood pressure and heart failure. It belongs to a class of drugs known as diuretics, which help the body get rid of excess fluid by increasing urine production. This can be particularly helpful for people with swelling or fluid retention due to various health issues. Additionally, spironolactone is often prescribed for hormonal imbalances, such as those seen in polycystic ovary syndrome (PCOS). It works by blocking the effects of the hormone aldosterone, which can lead to improved symptoms like acne and excessive hair growth. Overall, spironolactone is a versatile medication with multiple uses.
