MedDataToolAldactone is a medication used to treat conditions like heart failure, high blood pressure, and fluid retention due to liver or kidney issues. It works by blocking a hormone that causes your body to hold onto salt and water, which helps you get rid of excess fluid and lowers your blood pressure. You typically start with a dose of 25 mg to 100 mg daily, depending on your condition, and your doctor may adjust it as needed. It's important to know that Aldactone can raise potassium levels in your blood, so it should not be taken if you have high potassium levels. Additionally, be cautious if you're taking other medications that can also increase potassium, such as certain blood pressure drugs.
