Aldactone (spironolactone) is an aldosterone receptor antagonist that causes the kidneys to remove water and sodium from the body, with reduced losses of potassium. Aldactone is used to reduce edema caused by heart, liver or kidney problems, hypertension, and certain patients with hyperaldosteronism. Aldactone is available in a generic form named spironolactone. Common side effects of Aldactone include skin rash, headache, dizziness, and GI symptoms of nausea, vomiting, gas, and stomach pain.
Aldactone is available in 25, 50 and 100 mg tablets. Serious side effects of Aldactone include hyperkalemia, altered heart beats, confusion, tremors, decreased or no urine output, shallow breathing, muscle pain or weakness, and numbness. Because of tumor formation in experimental animals, use in pregnancy should be avoided unless the benefits outweigh the potential risks to the fetus; women who are breastfeeding are advised not to use Aldactone. In addition, the drug should not be used to decrease the normal edema of pregnancy. Aldactone has not been proved safe or effective in the pediatric population.
