Struggling with hormonal acne or unwanted hair growth? Spironolactone could be the solution.
Spironolactone is a prescription medication commonly used to treat acne and hirsutism, especially in women with PCOS. It works by blocking androgen hormones that cause excess oil production and unwanted hair growth. Here's what you need to know:
- For acne: Typical doses range from 50–100 mg/day, with results often visible after 3–6 months.
- For hirsutism: Higher doses of 100–200 mg/day are used, with noticeable effects taking 6–12 months.
- Safety monitoring: Regular blood tests for potassium and kidney function are essential, especially during the first few months.
- Combination treatments: Pairing spironolactone with birth control pills or topical treatments can enhance results.
Spironolactone is especially effective for PCOS-related symptoms, offering clear skin and reduced hair growth when other treatments fail. Always consult your doctor to find the right dosage and ensure safe use.

Emmy M. Graber, MD - What dose of spironolactone do you typically use in your acne patients?
Spironolactone Dosage Guidelines
Determining the right dose of spironolactone depends on whether it’s being prescribed for acne, hirsutism, or both. Healthcare providers usually start with a low dose and gradually adjust it based on how well you respond and tolerate the treatment. The dosage approach varies by condition, with hirsutism often requiring higher doses than acne.
Dosage for Acne Treatment
For acne, initial doses typically fall between 25–50 mg per day, with many providers starting at 50 mg. Dr. Patrick Mahar, a dermatologist, explains:
"The lowest dose of spironolactone for acne is usually 50 mg per day."
Most patients see results with daily doses ranging from 50–100 mg, though some resistant cases may require up to 200 mg. Dr. Mahar adds:
"The typical spironolactone dose recommended for acne patients varies from 50 to 200 mg per day."
Research shows that nearly two-thirds of participants experienced complete acne improvement with 100 mg daily. Women often report a 50% to 100% reduction in acne on the face and body after 12 weeks of treatment. For most acne cases, providers recommend doses between 50 and 150 mg daily for 1–2 years, sometimes including periodic breaks in treatment.
Higher doses are more common for treating hirsutism.
Dosage for Hirsutism Treatment
Hirsutism generally requires larger doses, with common recommendations ranging from 100 to 200 mg daily. Treatment often starts at 100 mg per day. One study found that this dosage improved excessive hair growth and reduced the Ferriman-Gallwey score by an average of 38.4%.
Treatment for hirsutism typically lasts around two years, with dosages maintained between 100–200 mg daily. While higher doses may yield better results for some, individual responses can vary significantly.
| Condition | Initial Dose | Maintenance Dose | Treatment Duration |
|---|---|---|---|
| Acne | 25–50 mg/day | 50–100 mg/day | 1–2 years |
| Hirsutism | 100 mg/day | 100–200 mg/day | 2 years |
How to Adjust Doses for Best Results
Doses are usually adjusted gradually - every 2 weeks or, in some cases, every 6–8 weeks - to monitor how well the treatment is working. Spironolactone tablets come in strengths of 25, 50, and 100 mg, allowing for precise dose adjustments.
Improvements in acne are often noticeable within 6–8 weeks, while hirsutism may take 6–12 months to show significant changes. Even then, only 50% to 75% of patients report improvement with current hirsutism treatments.
Other factors, such as age, kidney function, overall health, and medications, influence dosing decisions. For instance, women over 45 may need more frequent potassium monitoring. If potassium levels rise or kidney issues develop, dose reductions might be necessary.
Safety is a priority when adjusting doses. Providers aim to find the smallest effective dose for long-term use. Side effects like irregular periods, which affect 15–30% of patients, may lead to dose adjustments or changes in the treatment plan.
Patience and consistent communication with your healthcare provider are critical for successful spironolactone treatment. Always consult your doctor before making any changes to your dosage, and never stop taking spironolactone without medical guidance.
Monitoring and Safety Requirements
When it comes to spironolactone, keeping a close eye on your health ensures the treatment works effectively while minimizing risks. Regular check-ins with your healthcare provider help catch potential issues early. Your monitoring schedule will be tailored to factors like kidney function, age, and any other medications you're taking.
Blood Tests and Blood Pressure Checks
Keeping tabs on kidney function and potassium levels is a top priority while using spironolactone. Before starting treatment, your doctor will run baseline tests for kidney function and electrolytes. Once treatment begins or your dose changes, expect weekly checks for blood pressure and kidney health during the first month. After that, monitoring typically shifts to monthly for the next three months. For those on low doses (12.5–25 mg), potassium and creatinine levels should be tested 5–7 days after starting, then weekly until the results stabilize. Once stable, testing can be reduced to every 3–6 months, as hyperkalemia (high potassium levels) can develop without obvious symptoms.
"Appropriate monitoring during treatment of hypertension allows potentially serious underlying conditions to be identified and adverse events avoided", says Una Martin, Senior Lecturer in Clinical Pharmacology.
The risk of serious hyperkalemia depends on the individual. For instance, patients with early-stage chronic kidney disease have a less than 1% chance of developing severe hyperkalemia (potassium levels over 6 mmol/L). However, those with a baseline creatinine of ≥1.5 mg/dL face a much higher risk, with 35% experiencing hyperkalemia. Alarmingly, one study found that 34% of patients didn’t have their potassium or creatinine levels checked within three months of starting treatment, leaving them vulnerable.
Here’s how serum potassium levels guide treatment adjustments:
| Serum Potassium Level | Action to Take |
|---|---|
| <5.4 mmol/L | No changes needed |
| 5.5–5.9 mmol/L | Reduce dose to 25 mg every other day |
| 6.0–6.4 mmol/L | Stop for one week, then restart at 25 mg every other day |
| ≥6.5 mmol/L | Stop treatment immediately and seek medical help |
These steps help ensure safe dosing and reduce risks.
Managing Side Effects
Beyond lab tests, it’s important to watch for side effects. Women may experience menstrual irregularities, which often require dose adjustments. Signs of hyperkalemia - like muscle weakness, irregular heartbeat, or other heart-related symptoms - should prompt immediate medical attention.
Diet also plays a role in managing risks. Avoid potassium supplements, salt substitutes with potassium, and high-potassium foods. If blood pressure drops too much, it could cause dizziness or lightheadedness. To minimize this, rise slowly from sitting or lying positions and stay hydrated.
Drug interactions are another key concern. Spironolactone interacts with over 100 medications, so it’s crucial to share a complete list of your prescriptions and supplements with your healthcare provider. Special caution is needed when combining spironolactone with ACE inhibitors, ARBs, NSAIDs, or other potassium-sparing drugs.
Seek immediate medical help if you notice symptoms like yellowing skin or eyes, reduced urination, confusion, severe allergic reactions, or signs of high potassium. Additionally, stop taking spironolactone and contact your doctor if you experience vomiting, diarrhea, or fever with sweating.
Certain groups need extra care. Women over 45, individuals with diabetes, those with kidney issues, and patients taking multiple medications should have more frequent follow-ups. Women of childbearing age should use reliable contraception, as spironolactone can affect fetal development.
Combining Spironolactone with Other Treatments
Spironolactone's ability to block androgens makes it a powerful tool, but its benefits can be amplified when paired with other therapies. For those managing acne or hirsutism, especially when linked to PCOS, combining spironolactone with additional treatments often leads to more effective results. Depending on your specific symptoms and health profile, your healthcare provider may suggest a multi-faceted approach to address hormonal imbalances and related issues.
Using Birth Control Pills with Spironolactone
Estrogen-progestin birth control pills are a natural partner for spironolactone in treating acne and PCOS symptoms. While spironolactone blocks androgen receptors, these pills tackle the problem from another angle by regulating menstrual cycles and reducing overall androgen levels. A 2017 study showed that women with PCOS who combined these therapies saw better improvements in hirsutism, lower testosterone levels, and more regular menstrual cycles compared to those using metformin alone.
Third- and fourth-generation pills containing agents like desogestrel, norgestimate, or drospirenone are particularly effective for acne and provide the added benefit of contraception. However, progestin-only pills are generally avoided, as they may worsen acne symptoms. Another plus? Spironolactone’s mild diuretic effect can counteract the potential blood pressure increases sometimes associated with oral contraceptives. Research suggests that combining these treatments for at least 24 weeks yields optimal results.
Beyond hormonal contraceptives, other treatments can further improve outcomes.
Adding Topical Treatments and Metformin
When hormonal therapies alone aren't enough, additional treatments can help achieve better results. Topical treatments remain a cornerstone of acne care and work well alongside oral spironolactone. For instance, pairing spironolactone with topical retinoids or benzoyl peroxide offers a multi-layered approach to tackling acne. Experts Miriam Santer and Alison Layton note, “For women with acne that persists despite topical treatment, prescribing oral spironolactone alongside topical treatment can reduce long-term oral antibiotic use”. Topical spironolactone can also be combined with ingredients like tretinoin or niacinamide for enhanced results. Studies comparing topical spironolactone with clindamycin have shown that spironolactone significantly reduces comedones and pustules.
While topical treatments address acne externally, metformin targets a key internal factor in PCOS: insulin resistance. This is especially crucial, as more than half of women with PCOS are at risk of developing diabetes by age 40. As an insulin sensitizer, metformin complements spironolactone by addressing hyperandrogenism. Research highlights that combining metformin with spironolactone can lead to improved BMI, reduced androgen levels, and better fasting blood glucose and insulin sensitivity - especially when treatment lasts six months or more. Timing matters, as spironolactone is particularly effective for managing hirsutism and menstrual irregularities, while metformin serves as a first-line therapy for addressing insulin resistance in PCOS patients.

When to Expect Results
Once you've established the right dosage and ensured safety through proper monitoring, it’s important to understand how long it might take to see results. This helps set realistic expectations. The time it takes for spironolactone to work varies depending on the condition being treated - acne and hirsutism follow different timelines due to their unique biological processes.
Acne Improvement Timeline
For acne, initial improvements often begin within the first three months of treatment, with noticeable reductions (ranging from 50% to 100%) typically seen by the 12-week mark. Some people may even notice less oiliness in their skin within just a few weeks. However, the most significant effects usually occur between 4 and 6 months.
The British Association of Dermatologists notes: "Most women find that their acne starts to improve after about 3 months of treatment". Clinical guidelines echo this, highlighting that it can take 3 to 6 months for acne improvement to become apparent. For some, it may require up to three months for initial results and up to five months for full effectiveness.
Research supports spironolactone’s effectiveness. In a study involving 400 women, 93% of those who had never tried acne treatments before saw improvement, and 87% of those who had previously used other treatments also experienced benefits.
Consistency is absolutely key during this process. Peak results are typically seen between 4 and 6 months of treatment. Even if results aren’t immediate, sticking to your prescribed regimen daily offers the best chance for success.
Now, let’s look at how spironolactone works for hirsutism.
Hirsutism Improvement Timeline
Hirsutism takes longer to respond. Initial signs of improvement often appear around the 6-month mark, with the most noticeable benefits occurring between 6 and 18 months. This is because hair follicles respond more slowly to treatment.
It can take up to six months to see a significant reduction in hair growth, which aligns with the natural life cycle of hair follicles. Medical experts agree that drug therapy for hirsutism typically requires 6 to 18 months for the best results. This underscores the importance of patience and long-term commitment.
The process of improvement usually follows a predictable pattern. With daily doses of 100-200mg over two years, the first change is a slower rate of hair growth, followed by finer hair texture, and eventually, a decrease in the overall amount of hair. You may notice subtle changes before more dramatic improvements become evident.
Long-Term Treatment Plans
For lasting results, it’s important to continue treatment even after achieving clear skin or reduced hair growth. Regular follow-ups with your healthcare provider help fine-tune the dosage, minimize side effects, and reduce the risk of relapse.
In acne treatment, healthcare providers recommend maintaining the effective dose for at least two months after clear skin is achieved. After this stabilization period, you and your provider can discuss whether to reduce the dose or stop treatment, depending on your risk of symptoms returning.
Several factors can influence your timeline, including other treatments you’re using, how often you attend follow-ups, your dosage, and the overall duration of treatment. Women combining spironolactone with birth control pills or topical treatments may experience different timelines compared to those using spironolactone alone.
Taking your medication daily as directed, even if results aren’t immediate, significantly increases your chances of success. Staying consistent with follow-ups and following additional recommendations from your healthcare provider, such as using specific cleansers or complementary treatments, can further improve your outcomes.

Conclusion
Spironolactone stands out as a solid long-term option for women managing hirsutism and acne tied to PCOS. Its ability to target hormonal imbalances - by blocking androgens and reducing testosterone production - addresses the root cause of these symptoms. Research involving nearly 400 women revealed that almost two-thirds experienced a complete resolution of acne symptoms within 3–5 months when taking a daily dose of 100 mg.
The benefits don’t stop at acne. Spironolactone is also effective against hirsutism, with noticeable results typically emerging between six and 12 months. This dual action makes it especially helpful for women with PCOS, who often face multiple androgen-related issues at the same time.
Another key advantage is its safety for long-term use. Studies have shown that extended treatment with spironolactone does not negatively affect glucose metabolism or lipoprotein levels. When paired with lifestyle changes like weight loss, its positive effects can be even greater.
Access to this treatment has also been made easier through telehealth platforms. With PCOS affecting up to one in 10 women of reproductive age and 70% of cases remaining undiagnosed, the ability to access care remotely is vital. Services like Oana Health provide personalized prescriptions, making spironolactone more accessible than ever.
Dr. Sara Martinez, a board-certified endocrinologist specializing in women’s health, highlights the importance of telemedicine:
"Telemedicine is bridging the gap where PCOS specialists were once out of reach."
Telehealth has even been shown to improve medication adherence by 45% for PCOS patients compared to traditional care. For women dealing with unwanted hair growth and persistent acne, spironolactone offers a reliable, science-supported solution that’s both effective and accessible.
FAQs
Why does spironolactone dosage differ when treating acne versus hirsutism in women with PCOS?
Spironolactone is a medication that works as an anti-androgen, making it effective for managing both acne and hirsutism by counteracting the effects of androgens like testosterone. When it comes to acne, lower doses - typically between 50–100 mg per day - are often sufficient. This is because it helps reduce oil (sebum) production and blocks androgens from triggering breakouts.
On the other hand, treating hirsutism usually requires higher doses, ranging from 100–200 mg per day. This is due to the more intense androgen activity involved in unwanted hair growth, which calls for a stronger suppression of androgen receptors. The dosage differences highlight the unique biological mechanisms and severity of each condition.
For tailored, science-based care addressing PCOS-related symptoms, Oana Health provides expert telehealth services and prescription treatments conveniently delivered to your home.
What precautions should I take when starting spironolactone, and how often do I need blood tests?
When starting spironolactone, keeping an eye on your potassium levels and kidney function is key to making sure the medication works safely and effectively. Typically, your doctor will suggest a blood test about one week after starting the treatment. For the first three months, you’ll likely have monthly tests, and after that, the schedule will depend on your specific situation and what your doctor advises.
These regular checks are essential to catch any potential side effects early and to ensure your treatment stays on course. Always stick to your healthcare provider's recommendations and let them know right away if you notice anything unusual.
Can spironolactone be used with other treatments to improve results for hirsutism and acne?
Yes, spironolactone can be used alongside other treatments to improve its effectiveness in managing hirsutism and acne, particularly for women dealing with PCOS. One popular combination is spironolactone paired with oral contraceptive pills (OCPs). OCPs not only enhance the effects of spironolactone but also help regulate menstrual cycles and reduce androgen levels, which can further alleviate symptoms.
Another effective pairing is spironolactone with metformin. Metformin can address insulin resistance, lower androgen levels, and support weight management, making it a valuable addition for a more well-rounded approach to managing PCOS-related symptoms. These combinations often lead to better results for many women. Always consult your healthcare provider to create a treatment plan tailored to your needs.
