Spironolactone: Uses, Side Effects, Safety, Recalls and More

What is Spironolactone?

Spironolactone is a medication primarily used to treat high blood pressure, heart failure, and edema (fluid retention) caused by various conditions such as liver disease, kidney disease, or heart failure. It belongs to a class of medications known as potassium-sparing diuretics, which help the body get rid of excess salt and water while retaining potassium.

In addition to its use as a diuretic, spironolactone is also prescribed off-label for certain dermatological conditions, particularly acne and hirsutism (excessive hair growth), due to its anti-androgenic properties. It works by blocking the effects of the hormone aldosterone, leading to decreased sodium and water retention and increased potassium retention. It also has anti-androgenic effects by blocking the action of androgens (male hormones) on the skin's oil glands and hair follicles, which can be beneficial in treating acne and hirsutism in some individuals.

However, it's important to note that spironolactone should only be taken under the supervision of a healthcare professional, as it can have potentially serious side effects and interactions with other medications.
