Summary
Spironolactone is used to ease fluid buildup in the body caused by conditions like heart failure, liver disease, or kidney problems. It also helps lower high blood pressure and is used for certain types of high blood pressure related to the adrenal glands.
Spironolactone works by blocking a hormone that makes your body hold onto salt and lose potassium. This action helps lower blood pressure and reduces swelling. It also helps your body keep potassium, an important mineral.
The dosage of Spironolactone varies depending on what it's treating. For heart problems and high blood pressure, the dose might start low and be adjusted based on your response. For swelling from liver disease, the dose starts higher and can be increased. It's usually taken orally.
Common side effects of Spironolactone include high potassium levels, low blood pressure, and kidney problems. It can also cause imbalances in other salts in your body and high blood sugar. In men, it might cause breast growth.
Spironolactone can raise your potassium levels, especially if you have kidney problems or take other medicines that also raise potassium. You shouldn't take it if you have high potassium, Addison's disease, or are taking a similar medicine called eplerenone. Pregnant women also shouldn't take it.
Indications and Purpose
How does Spironolactone work?
Spironolactone works by blocking a hormone called aldosterone, which helps your body retain sodium and water. By blocking this hormone, Spironolactone helps your body remove excess fluid and sodium while retaining potassium. Think of it like a sponge that releases water but keeps important minerals. This action helps lower blood pressure and reduce swelling. Spironolactone is effective for conditions like hypertension, which is high blood pressure, and heart failure, which is when your heart can't pump blood effectively.
