This is one of the most important questions to ask about Spironolactone, and the answer matters: Spironolactone is not safe during pregnancy.
Here's the core of it. Spironolactone can interfere with the development of a male fetus — specifically, it can affect the normal development of male reproductive tissues during pregnancy. Because of this, Spironolactone is contraindicated during pregnancy and should be stopped before you start trying to conceive.
A few specifics:
- Stop Spironolactone before trying to conceive. There's no required waiting period after stopping — meaning you don't need to wait weeks or months between your last dose and starting to try. Many women stop the day they decide they're ready to try. That said, your Oana clinician will give you specific guidance based on your case.
- Spironolactone does not affect your ability to get pregnant. It's a medication you stop because of fetal safety concerns — not because it impairs fertility. Many women have conceived shortly after stopping Spironolactone with no issues.
- There are no documented long-term effects on reproduction. After stopping, Spironolactone clears your body relatively quickly, and there's no evidence of persistent effects on future pregnancies once you've stopped.
- The symptoms Spironolactone was treating will likely return. This is the harder part of stopping. Acne, unwanted hair, and hair loss patterns are typically driven by the same hormonal picture that was there before treatment — and they often return when treatment stops. Your clinician can help you plan for this, including pregnancy-safe alternatives where they exist.
If you're considering pregnancy in the next 12 months, mention this in your medical intake. Your Oana clinician may discuss whether Spironolactone is still the right starting point, whether to wait, or how to plan a transition off treatment when you're ready to try. There's no rush — but the planning conversation matters.
If you're already taking Spironolactone and unexpectedly become pregnant, message your clinician immediately. The standard guidance is to stop Spironolactone right away and discuss next steps with both your Oana clinician and your OB-GYN.
