Spironolactone is used less often than other drugs to treat high blood pressure. It is used when other drugs have not helped bring the blood pressure down. It is also a good choice if you have swelling from water buildup, heart failure, kidney problems, or liver disease.
Some people have high blood pressure caused by a rare hormone disorder. The condition is called primary hyperaldosteronism. Spironolactone is the best drug for this condition.
It’s proven its stuff, and that’s enough!
