Spironolactone Q&A with Dermatologist Dr. Jenny Liu
Study Details and Goals
This 8-year study examines the long-term safety of spironolactone as an antiandrogen for treating acne and other hormonal conditions. While the medication has been used off-label for over two decades, comprehensive safety data has been lacking - until now. These findings provide a clearer picture of how spironolactone performs with prolonged use in real-world settings.
Who Was Studied and How
The study tracked 91 women over a total of 506 person-years, with an average treatment duration of 28.5 months (ranging from 0.5 to 122 months). This broad range of treatment durations mirrors everyday use, making the results more applicable to clinical practice. Such real-world evidence strengthens the reliability of the safety evaluations.
For comparison, the SAFA trial specifically studied women aged 18 and older with facial acne persisting for at least six months. Participants in this trial had a baseline mean age of 29.2 years. The SAFA trial excluded women who had previously used spironolactone, those planning to become pregnant within six months, and individuals with kidney function issues.
Why 8-Year Studies Are Important
The design of this study highlights the importance of extended research in evaluating spironolactone's long-term safety and effectiveness. Short-term studies often miss delayed side effects or benefits, making longer research periods essential.
Large-scale studies, such as the WHI, further stress the value of long-term hormonal therapy data tailored to individual needs.
"Findings from the clinical trials and study observations can vary based on multiple factors, such as age and underlying cardiovascular disease risks, so women ages 50 and older should work with their clinicians to make individualized and shared medical decisions." - National Institutes of Health (NIH)
For spironolactone, extended studies are critical in identifying the frequency and severity of side effects over time. This helps patients and doctors weigh the risks and benefits, especially for younger women who might rely on the medication for years to manage hormonal acne.
In this study, side effects were reported in 59% of cases, with 15% of participants discontinuing treatment due to these effects. However, even after 200 person-years of spironolactone exposure, no serious illnesses were linked to the medication. These findings provide valuable guidance for making informed treatment decisions.
Long-term research also aids in creating personalized treatment plans by offering insights into how different groups of women respond to spironolactone over time. This allows healthcare providers to better predict outcomes and tailor treatments to meet individual needs effectively.
Safety Results from the Study
An 8-year safety study highlights that while spironolactone can cause common side effects, it remains a reliable long-term treatment option. Serious health risks are rare, and most women are able to continue using it successfully.
Most Common Side Effects
The study provides detailed insights into the most frequently reported side effects. Menstrual irregularities - such as breakthrough bleeding, amenorrhea, and irregular cycles - were observed in roughly 22–29% of users. These findings align with a retrospective study conducted by the University of Pennsylvania Health System, which examined 110 women using spironolactone to treat acne.
In the Pennsylvania study, diuretic-related side effects like dizziness or lightheadedness were reported by 7 women, and 4 noted increased urinary frequency. Among the 51 women who experienced side effects, only 6 found them bothersome enough to stop treatment. Breast-related changes, including tenderness in 4 women and enlargement in 2, were also noted. Other less common effects included minor weight changes, sleep disruptions, and mild skin reactions.
Cancer Risk and Serious Health Concerns
The study also addresses concerns tied to the FDA's warning label regarding cancer risk. Over 506 person-years of follow-up, no serious illnesses were linked to spironolactone. Moreover, large-scale reviews involving millions of patients across multiple studies found no significant connection between spironolactone use and cancers of the breast, ovary, bladder, kidney, stomach, or esophagus. While the FDA recommends cautious use, real-world data suggests that when used at standard clinical doses, spironolactone is unlikely to increase cancer risk.
Hyperkalemia, or elevated potassium levels, remains the most serious potential side effect, especially for older women or those with kidney problems. According to the FDA's adverse event database, hyperkalemia accounted for 16.06% of reported side effects among women taking spironolactone. However, this risk can be effectively managed through careful patient selection and consistent monitoring.
Benefits vs. Risks Breakdown
The findings reveal a clear balance between the benefits and manageable risks of spironolactone.
Benefits | Risks |
---|---|
Effective for long-term acne treatment | Menstrual irregularities in 22–29% of users |
No increased cancer risk in large-scale studies | Diuretic effects like dizziness or frequent urination in some users |
Low discontinuation rate (15%) | Breast tenderness or enlargement in a small number of cases |
Proven safety over 8 years of use | Risk of hyperkalemia, especially in patients with kidney issues |
Helps with other hormonal conditions | Requires regular blood monitoring |
Most side effects are manageable | Some women may experience fatigue or mood changes |
With an 85% continuation rate in the 8-year study, most women found the benefits of spironolactone outweighed the drawbacks. For those struggling with persistent hormonal acne, this evidence offers valuable guidance. The treatment's combination of effectiveness, manageable side effects, and reassuring long-term safety makes it a compelling option for achieving hormonal balance.
How Well Spironolactone Works for Acne and Other Conditions
Spironolactone has a well-documented safety record and is widely recognized for its effectiveness in treating acne and other hormone-related conditions. Many women dealing with persistent acne, unwanted hair growth, or hair loss have reported noticeable improvements when using this treatment.
Acne Improvement Results
Spironolactone is particularly effective at managing hormonal acne, with studies showing that it helps about 60% to 65% of women experiencing this condition. The results become even more striking when focusing on specific groups of patients.
In a 2017 study, 93% of women new to acne treatment and 87% of those already on other therapies experienced improvements. Among these women, 55% achieved completely clear skin, while another 30% saw significant improvement.
Its benefits extend beyond facial acne. For example, the medication cleared acne on the chest in 84% of cases and on the back in 80.2% of cases, highlighting its effectiveness for acne across different areas of the body.
"Spironolactone is an effective acne treatment with clinical trial data to support its use as a first-line acne treatment for women with acne." - Courtney A. Smith, Emily Gosnell, Turkan Banu Karatas, Howa Yeung
Results for Different Groups of Women
Spironolactone’s success spans a wide range of age groups and hormonal profiles. It’s especially helpful for women in their 20s and 30s dealing with hormonal acne, as well as for women going through perimenopause or menopause. This versatility makes it a practical option for women at different stages of life.
For women with polycystic ovary syndrome (PCOS), the medication often delivers excellent results. By targeting the elevated androgen levels typical of PCOS, spironolactone helps manage symptoms like cystic acne, comedones, and excessive body hair.
The medication is effective both as a standalone treatment and when combined with other therapies. Beyond acne, it also addresses other androgen-driven conditions, such as female pattern hair loss and hirsutism (excessive body hair). By blocking the effects of androgens and progesterone, spironolactone reduces hormonal activity in hair follicles and sebaceous glands, addressing these issues at their source.
"Spironolactone helps with skin and hair conditions that are caused by androgens including: Hormonal acne for women in their 20's and 30's, Acne during the perimenopause, Acne caused by HRT or Testosterone as part of HRT, Female pattern hair loss, Excessive body hair." - Midland Skin
How Long Before You See Results
While spironolactone is highly effective, it’s important to understand the treatment timeline to set realistic expectations. Some women may notice early changes within a few weeks, but full results typically take several months.
Most women see significant improvements between 3 to 6 months, with the medication reaching peak effectiveness by around 5 months. Dr. Joshua Zeichner, director of cosmetic and clinical research in dermatology at Mount Sinai Hospital, explains:
"Spironolactone results typically appear within a few weeks, but the drug reaches 'peak effect' at around three months."
The British Association of Dermatologists echoes this, noting that most women begin to see improvement after about 3 months of treatment.
Consistency is key during this period. Taking the medication daily as prescribed, even if results aren’t immediately visible, allows it to build up to therapeutic levels in the body. Regular follow-ups with healthcare providers are essential to monitor progress and make any necessary adjustments to the dosage.
This gradual approach reflects how spironolactone works at the hormonal level, reducing androgen activity over time. While slower than some treatments, its steady and sustained effects often lead to longer-lasting improvements compared to quick but short-lived solutions.

Medical Guidelines and Recommendations
Starting spironolactone requires close medical supervision and regular check-ups to ensure both its safety and effectiveness. Healthcare professionals follow established protocols for dosing, monitoring, and managing potential risks, particularly for women of reproductive age.
Dosing and Medical Monitoring
Spironolactone is available in 25mg, 50mg, and 100mg tablets, allowing doctors to tailor the dose to each patient’s needs. Most treatments begin with a conservative dose of 25–100mg daily, which is gradually increased every 6 to 8 weeks until noticeable acne improvement occurs. Research suggests that even lower doses, such as 25–50mg daily, can be effective for adult female acne. The typical dosing range falls between 50 and 200mg per day, with 200mg daily being the maximum recommended dose.
Patients on spironolactone require periodic blood tests to monitor potassium levels and kidney function. The British Association of Dermatologists advises checking potassium levels before starting treatment and conducting occasional follow-ups during the course of therapy. More frequent testing may be necessary for individuals with heart or kidney conditions or those taking medications that affect potassium levels.
Monitoring is essential because spironolactone can cause hyperkalemia (elevated potassium levels), which is its most common electrolyte-related side effect. Additionally, the medication may lead to a drop in blood pressure when transitioning from sitting to standing, causing dizziness, lightheadedness, or fainting. These risks underscore the importance of careful dosing and monitoring, especially for women of reproductive age.
Important Notes for Women Who Can Get Pregnant
For women of reproductive age, spironolactone presents specific concerns. The medication can affect male fetal development if taken during pregnancy, making effective pregnancy prevention a priority.
The British Association of Dermatologists advises:
"Do not take this medication if you are pregnant or planning to become pregnant as it can affect the normal development of your unborn child. Women taking spironolactone should use effective contraception to prevent pregnancy."
Women taking spironolactone must use effective contraception, and it is common for healthcare providers to prescribe spironolactone alongside oral contraceptives, as the two are safe to use together.
For those planning to conceive, spironolactone can typically be discontinued a month before trying to get pregnant, minimizing delays in family planning. However, women should be aware that spironolactone may occasionally disrupt menstrual cycles or, at higher doses, cause temporary infertility. These effects usually resolve after stopping the medication.
Breastfeeding mothers should consult their healthcare provider before starting or continuing spironolactone, as individualized advice is crucial in these cases. With proper planning and monitoring, spironolactone treatment can be safely managed for women at different life stages.
Long-Term Treatment Plans
Effective treatment with spironolactone relies on a personalized, evolving approach. Regular check-ins with healthcare providers help determine the lowest effective dose while minimizing side effects. Patients should never adjust their dosage without consulting their doctor, and any missed doses should be managed according to medical advice.
Managing spironolactone treatment often involves collaboration among various specialists. For instance, endocrinologists can assist with managing diabetes, while nephrologists may monitor kidney health in patients with compromised renal function. Since spironolactone interacts with over 100 medications, pharmacists play a key role in reviewing and reconciling a patient’s medication list to avoid harmful interactions.
Communication between healthcare providers is essential for safe and effective treatment. Doctors and pharmacists must work together to identify and address any potential interactions or contraindications.
The decision to continue or stop spironolactone depends on individual factors such as treatment response, side effects, and life changes. While some women may require long-term use to maintain clear skin, others may be able to reduce their dosage or discontinue the medication after achieving their desired results.

What should women know about taking spironolactone if they're planning to get pregnant?
If you're planning to become pregnant and are currently taking spironolactone, there are a few critical steps you need to take. First and foremost, talk to your healthcare provider to determine if continuing this medication is safe for you. Spironolactone is generally not recommended during pregnancy due to the potential risks it poses to fetal development, particularly for male fetuses.
Second, ensure you're using reliable birth control while on spironolactone to avoid an unplanned pregnancy. If you do find out you're pregnant, stop taking the medication immediately and reach out to your doctor. They can help you transition to safer alternatives that will protect both your health and your baby during pregnancy.
It's important to note that spironolactone is classified by the FDA as a category C drug during the first trimester and category D in later stages. This means the potential risks to the fetus become more concerning as the pregnancy progresses. Always rely on professional medical guidance to make informed decisions about managing hormonal conditions while planning for pregnancy.
How does spironolactone help with hormonal issues beyond acne, and what should long-term users watch out for?
Spironolactone is widely recognized for its role in treating hormonal acne, but its benefits extend beyond that. By blocking androgen receptors and lowering testosterone levels, this medication can help manage conditions like PCOS, hirsutism (excessive hair growth), and alopecia (hair loss). This makes it a helpful option for women dealing with symptoms linked to hormonal imbalances.
That said, long-term use can sometimes lead to side effects. Common issues include menstrual irregularities, breast tenderness, and elevated potassium levels, which can occasionally become serious. More rarely, severe side effects like dizziness or an irregular heartbeat may arise. To use spironolactone safely, it's important to have regular check-ins with a healthcare provider to monitor for any potential risks.
