Never stop, pause, reduce, or change a prescribed medicine because of anything on this page. Some of the medicines listed here are dangerous to stop suddenly, and the condition being treated does not pause while you experiment. Everything here exists to make your next conversation with a prescriber more specific — not to replace it.

Aldactone and sexual side effects
Aldactone is a brand name for spironolactone, which belongs to the class this site calls Spironolactone. Everything below describes that class.
This page exists because people search for a medicine by name, not by drug class. Everything below describes the class this medicine belongs to. Nothing here says this particular medicine is better, worse, or different from the others in its class — this site does not rank medicines against each other, and that is a conversation for whoever prescribed it.
How this class affects sex
Spironolactone blocks androgen receptors as a side activity, which is exactly why it is also prescribed for acne, hirsutism, and as part of feminising hormone therapy. That same anti-androgen action commonly reduces desire and, in people with testosterone-driven erectile function, causes erection difficulty and breast tenderness. The effect is intended in some prescriptions and unwanted in others.
What the rating means: Sexual effects are among the better-documented effects of this class. Frequent does not mean inevitable — plenty of people take these with no change at all.
What is reported
Editorial categories for the class, not percentages, and not a prediction about you. Published rates vary enormously depending on study design and on whether anyone thought to ask the question.
Wanting sex less often, or losing the spontaneous interest that used to arrive on its own. This is the effect people most often assume is psychological and most often is not only psychological.
Erections that are slower, softer, or do not hold. Because this depends on blood vessels and nerves, it can also be an early signal of something cardiovascular — which is why it is worth a clinical conversation rather than only a product.
Less natural lubrication, a tight or raw feeling, or discomfort that arrives during rather than before sex. Medicines cause this either by drying mucous membranes generally or by lowering oestrogen.
The body responds less, or much more slowly, even when the interest is there. Blood flow, nerve signalling, and hormone levels all feed this, and medicines can act on any of the three.
When it tends to show up
Builds over weeks to months and is dose-related. It generally reverses after supervised discontinuation.
What helps without touching the medicine
A regular vaginal moisturiser plus a glycerin-free lubricant if dryness is the main symptom.
If it was prescribed for skin or hair rather than for heart failure, the trade-off is a legitimate thing to reweigh at review.

Can spironolactone affect your sex life?
Frequently reported for this class. Spironolactone blocks androgen receptors as a side activity, which is exactly why it is also prescribed for acne, hirsutism, and as part of feminising hormone therapy. That same anti-androgen action commonly reduces desire and, in people with testosterone-driven erectile function, causes erection difficulty and breast tenderness. The effect is intended in some prescriptions and unwanted in others.
Which sexual side effects are most reported with spironolactone?
The effects reported most often are lower sexual desire and difficulty getting or keeping an erection. Reported does not mean guaranteed — plenty of people take these medicines with no change at all, and published rates vary widely depending on whether anyone asked the question.
How soon would spironolactone cause a change, and does it reverse?
Builds over weeks to months and is dose-related. It generally reverses after supervised discontinuation.
What should I do if I notice this while taking spironolactone?
No. Never stop, pause, or reduce a prescribed medicine on your own because of a side effect — several medicines on this site are dangerous to stop suddenly, and the condition being treated does not pause while you experiment. Bring the observation to the person who prescribed it; a dose review, a different preparation, or a different approach may all be options, and only they can weigh them against what the medicine is doing for you.
What should I ask about spironolactone at my appointment?
A specific question gets a better answer than a general one. For this class: What is this treating for me specifically — heart, blood pressure, skin, or hair? Is the dose I am on the lowest that achieves that? Is the anti-androgen effect wanted here, or is it a side effect in my case?

Educational information about categories of medicine only — not medical advice, not a diagnosis, and not a statement about your prescription. It does not cover doses, interactions between medicines, or alternatives, and it cannot know what else is going on with your health. Sexual symptoms often have more than one cause at once. Pain, bleeding, or a symptom that is new and unexplained always deserves assessment.
