Aldactone (spironolactone) for hormonal acne


Aldactone ( spironolactone ) is a drug used to treat many different medical conditions. This includes things like high blood pressure and fluid retention.

Aldactone is also used to treat hormonal acne in adult women.

For people who break around the time of their menstrual cycle , this drug may be helpful. It can also be beneficial for adult women who have acne with other problems, such as unwanted facial hair.

The FDA does not officially recognize aldactone as an acne remedy. However, for this purpose it is often prescribed off-label. It is only available with a prescription.

This article explores the use of aldactone to treat hormonal acne. It also looks at how to take it and the possible side effects.

How Aldactone Works

Aldactone belongs to a group of drugs called antiandrogens. Androgens are often called male hormones, but both men and women have them.

Androgens like testosterone are present in the female body, but at a lower level. However, some women produce more androgen hormones than necessary.

Hormones, especially androgens, have been linked to the development of acne. Aldactone works by blocking androgen receptors in the body. This prevents cells from responding to androgen hormones.

Aldactone simply limits the hormonal fluctuations that can cause breakouts. Therefore, it is only effective against hormonal acne.

In some women, acne is caused by fluctuations in hormones. These patients can have good results with Aldactone.

How is aldactone used?

Unlike most acne treatments, Aldactone is not applied to the skin. Instead, it is taken orally. When Aldactone is used to treat acne, the most common dose is 50 to 100 milligrams (mg) per day.

Your dermatologist may prescribe a lower dose. Usually start with 25 mg per day and gradually increase to your target dose over several weeks. Your healthcare professional will prescribe the dosage based on your personal situation.

If the rash only occurs during your menstrual cycle , you may need Aldactone just one week before your period. It can help smooth out the hormonal spikes that cause acne.

Aldactone is often given together with oral contraceptives or birth control pills . You will likely continue to use topical acne medications while using Aldactone. It generally works best in conjunction with other acne treatments rather than as a single remedy.


Aldactone is taken by mouth. Most people start with a lower dose and increase until they reach their goal.

You may need to take aldactone just one week before your period. It works best with other acne treatments.
