Spironolactone is a medication that helps manage some of the most frustrating symptoms of PCOS, such as acne, unwanted hair growth, and hair thinning. It works by reducing the effects of androgens (male hormones) in the body, which are often elevated in women with PCOS. This guide explains how spironolactone works, its benefits, potential side effects, and safety considerations. Here's what you need to know:
- How it works: Blocks androgen receptors and reduces androgen production.
- Key benefits: Improves acne (67% see results in 3-5 months), reduces unwanted hair growth (up to 95% improvement in 6 months), and slows hair thinning.
- Side effects: May include dizziness, nausea, menstrual irregularities, and increased potassium levels.
- Who should avoid it: Not suitable for pregnant women or those with certain medical conditions like kidney issues.
- Monitoring: Regular blood tests for potassium and kidney function are necessary.
Spironolactone is often combined with treatments like birth control or metformin for better results. Telehealth services, such as Oana Health, make accessing this medication more convenient by offering online consultations and affordable monthly plans.
If you're considering spironolactone, consult a healthcare provider to ensure it’s the right fit for your symptoms and health needs.

How Spironolactone Works for PCOS
Spironolactone plays a key role in managing PCOS symptoms through a twofold approach. It not only blocks the effects of androgens but also reduces their production, making it a powerful tool for addressing the hormonal imbalances associated with the condition.
Blocking Androgen Receptors
One of spironolactone’s primary actions is its ability to block androgen receptors. It competes with testosterone and dihydrotestosterone (DHT) for binding sites on these receptors, effectively preventing the androgens from exerting their effects. This mechanism is particularly helpful for women with PCOS, who often have elevated androgen levels. Research reveals that spironolactone itself has a 3.0% binding affinity compared to DHT, while its metabolites, 7α-TMS and 7α-TS, show slightly higher affinities of 4.2% and 3.1%, respectively.
This receptor-blocking action delivers noticeable benefits. By inhibiting androgen activity, spironolactone reduces sebum production and limits the proliferation of sebocytes, which are key contributors to acne development. Additionally, it prevents testosterone from binding to hair follicle receptors, resulting in reduced unwanted hair growth. Clinical studies highlight its effectiveness: a daily dose of 100 mg decreases hair shaft diameter by 19% ± 8%, while 200 mg achieves a 30% ± 3% reduction. Another study found that nearly two-thirds of approximately 400 women taking 100 mg daily saw complete acne improvement within 3 to 5 months.
Effects on Hormonal Imbalances
PCOS is often accompanied by significant hormonal disruptions, with 75% to 90% of patients experiencing hyperandrogenemia - excess androgen levels that lead to symptoms like acne and hirsutism. Beyond blocking receptors, spironolactone addresses this issue by lowering androgen production in both the ovaries and adrenal glands.
Symptom improvement varies depending on the individual. Hirsutism reduction typically begins within 2 months, peaks around 6 months, and can continue for up to a year. Acne improvement, on the other hand, is usually noticeable within 2 to 4 months. By tackling both androgen activity and production, spironolactone helps restore hormonal balance, alleviating multiple PCOS symptoms at once. This makes it a valuable option, especially for those who don’t experience sufficient relief from first-line treatments like hormonal birth control after six months.
Spironolactone Benefits for PCOS Symptoms
Spironolactone provides relief for some of the most challenging symptoms of PCOS, which can affect both daily life and self-esteem. Its ability to counteract androgens makes it particularly effective in tackling many of the physical and cosmetic issues linked to the condition. Here's a closer look at its benefits.
Reducing Hirsutism and Unwanted Hair Growth
Unwanted hair growth is a common issue, affecting up to 80% of individuals with PCOS. Spironolactone works by blocking androgen receptors on hair follicles, helping to reduce this symptom. Clinical studies have shown that taking 200 mg daily led to significant improvements in facial hair. In fact, 95% of patients with moderate to severe hirsutism reported noticeable reductions in hair diameter, density, and growth rate within two months, with maximum results seen by six months and maintained for up to a year. Dosages ranging from 50 to 200 mg have been found to lower testosterone levels, further enhancing its effectiveness. Additionally, its mild diuretic properties can benefit those dealing with hypertension or fluid retention.
Treating Acne and Skin Issues
Spironolactone also addresses another frustrating symptom of PCOS: acne. Hormonal acne affects 30–40% of women with PCOS and is often resistant to standard treatments. By blocking the effects of androgens and progesterone on the skin, spironolactone reduces sebum production, helping to prevent breakouts. Research involving nearly 400 women found that 67% experienced complete improvement in acne symptoms within three to five months when treated with 100 mg daily. Another study showed that 93% of women new to acne treatments saw improvement, while 87% of those already on treatment benefited from adding spironolactone. In a separate analysis of 110 women, 55% achieved full clearance, and 30% reported significant improvement. Beyond active breakouts, spironolactone can also reduce skin oiliness, making future acne less likely.
Managing Hair Thinning and Hair Loss
Hair loss, often caused by elevated androgen levels, is another distressing symptom of PCOS. Spironolactone helps by reducing androgen production, which can slow hair thinning and even encourage regrowth. A systematic review found that 56.6% of patients experienced improvement in hair loss with spironolactone alone. When combined with minoxidil, the success rate increased to 65.8%, compared to 43.2% for spironolactone by itself. By lowering testosterone levels, spironolactone indirectly reduces dihydrotestosterone (DHT), a key factor in female pattern hair loss. While it does not directly target hair loss, its ability to balance hormones makes it a helpful option for women dealing with multiple PCOS-related symptoms.
Safety, Side Effects, and Monitoring
Spironolactone is an effective treatment for managing PCOS symptoms, but it requires close attention to safety and side effects to ensure its proper use. Like any medication, it comes with potential risks that need careful observation.
Common and Rare Side Effects
Most people taking spironolactone experience mild side effects that often improve over time. These include menstrual irregularities, breast tenderness, dizziness, headaches, increased urination, nausea, vomiting, diarrhea, dehydration, and mood changes.
One important consideration is that spironolactone can increase potassium levels, potentially leading to hyperkalemia. This risk is particularly higher for those with diabetes or kidney issues and tends to increase with age.
Rare but serious side effects include severe allergic reactions, low blood pressure with worsening kidney function, liver toxicity, and blood cell abnormalities. In studies involving heart failure patients, 2% of those on spironolactone experienced severe hyperkalemia, compared to 1% of patients on a placebo. Symptoms of dangerously high potassium levels can include muscle weakness, fatigue, nausea, vomiting, tingling sensations, breathing difficulties, heart palpitations, irregular heartbeats, and chest pain.
Safety Precautions
Pregnancy is one of the most critical contraindications for spironolactone. The medication is not recommended during pregnancy due to the potential risk of birth defects. Women of childbearing age should use reliable contraception while on spironolactone and discuss their options with a healthcare provider.
Certain individuals should avoid spironolactone entirely, including those with existing hyperkalemia, Addison's disease, or those taking eplerenone. Additionally, combining spironolactone with medications like ACE inhibitors, ARBs, NSAIDs, or potassium supplements can increase the risk of dangerous potassium levels.
Some hormonal contraceptives may help manage side effects such as breast tenderness and irregular periods. However, if nausea, vomiting, or diarrhea occurs while taking spironolactone, these contraceptives may become less effective.
These risks highlight the need for consistent monitoring and communication with healthcare providers.
Monitoring Requirements
Given the potential for side effects and drug interactions, regular monitoring is crucial. Before starting spironolactone, baseline tests should include serum creatinine (or creatinine clearance), estimated glomerular filtration rate (eGFR), urea, and electrolytes.
During the early stages of treatment or after adjusting the dose, monitoring becomes more frequent. Blood pressure should be checked before and after any dose changes, followed by a one-week assessment, and then monthly for the first three months.
Once the treatment stabilizes, ongoing monitoring every 3 to 6 months is recommended. This includes checking serum creatinine (or eGFR), urea, and electrolytes. Women over 45 should also have their potassium levels monitored regularly.
Healthcare providers may adjust the dosage based on test results. For example, the dose should be reduced if potassium levels exceed 5.5 mmol/L, creatinine exceeds 220 micromol/L, or eGFR drops below 30 mL/min/1.73m². Treatment must be stopped if potassium levels rise above 6 mmol/L, creatinine exceeds 310 micromol/L, or eGFR falls below 20 mL/min/1.73m².
Patients should also take precautions while using spironolactone. Avoid potassium-rich salt substitutes and limit high-potassium foods like bananas, avocados, pulses, nuts, and salmon. NSAIDs should only be used if prescribed, and any symptoms such as diarrhea, vomiting, or fever should be reported to a healthcare provider. If dizziness or fatigue occurs, avoid activities like driving or cycling.
Proper monitoring and precautions can help ensure the safe and effective use of spironolactone.

Who Should Consider Spironolactone for PCOS?
Spironolactone can be a game-changer for managing certain symptoms of PCOS, but it’s not the right fit for everyone. Some individuals are better suited for this treatment, and understanding who benefits most can help you decide if it aligns with your health needs. It’s also worth noting that spironolactone often works best when combined with other therapies.
Best Candidates for Spironolactone
Spironolactone is particularly helpful for women dealing with cyclical hormonal acne. According to Dr. Emmy M. Graber, women whose acne flares up before or after their menstrual cycles are excellent candidates for this medication. It’s especially effective for women in their 20s, 30s, and those experiencing perimenopause or menopause who face hormonally driven acne.
For women struggling with persistent hirsutism (excess hair growth), spironolactone has shown better results than finasteride, making it a strong option for this symptom.
Women using progesterone-only contraception may also benefit from spironolactone, as it helps address hormonal imbalances. Additionally, it can be effective for those experiencing female pattern hair loss alongside other PCOS symptoms.
Age can influence how well the medication is tolerated. Younger women typically have a lower risk of developing hyperkalemia, a condition involving elevated potassium levels, while older women require more careful monitoring. However, spironolactone is not suitable for women who are pregnant, planning to become pregnant, or breastfeeding, as it poses risks to the developing baby.
In many cases, spironolactone isn’t used on its own but as part of a broader treatment strategy to maximize its benefits.
Combining with Other Treatments
Spironolactone’s effectiveness often improves when paired with other therapies, especially since PCOS involves a combination of hormonal and metabolic issues.
One common pairing is with oral contraceptives, which not only enhance spironolactone’s ability to treat acne but also help minimize hormonal side effects.
Another effective combination is spironolactone and metformin. Metformin improves insulin sensitivity, while spironolactone reduces androgen effects, tackling two key aspects of PCOS. Studies show that this combination yields better results than either medication alone. For example, one study found that combining oral contraceptives and spironolactone over a year resulted in greater androgen reduction and symptom relief compared to metformin alone.
Topical treatments can also complement spironolactone, though users should be aware of potential skin dryness as a side effect.

FAQs
Can I take spironolactone with other PCOS medications like birth control or metformin?
Yes, spironolactone is often safely used alongside other medications to help manage PCOS symptoms. For instance, it’s commonly paired with birth control pills to address acne and reduce excess facial or body hair (hirsutism). Birth control can also regulate menstrual cycles and minimize side effects like irregular bleeding, which spironolactone might trigger when taken alone.
As for metformin - a medication frequently prescribed to improve insulin sensitivity in PCOS patients - spironolactone typically doesn’t cause significant interactions. That said, everyone’s body reacts differently to medications, so it’s essential to work closely with your healthcare provider to determine the right combination for your individual needs.
What should I know before starting spironolactone for PCOS, including possible side effects and monitoring needs?
Before beginning spironolactone for PCOS, it’s crucial to understand the possible side effects. These can include elevated potassium levels, breast tenderness, dizziness, dehydration, and irregular menstrual cycles. To ensure safety, regular checks on potassium levels, kidney function, blood pressure, and electrolyte balance are necessary throughout treatment.
It’s also important to note that spironolactone is unsafe during pregnancy due to the risk of birth defects. For this reason, using reliable contraception is strongly advised. Always work closely with a healthcare provider to address any side effects, track your progress, and make sure the treatment is effectively managing your symptoms.
Is it safe to use spironolactone long-term for managing PCOS symptoms?
Yes, spironolactone can be taken long-term to help manage PCOS symptoms like acne and unwanted hair growth (hirsutism), provided it's done under regular medical supervision. While long-term use is generally considered safe, it’s crucial to watch for possible side effects such as elevated potassium levels, changes in menstrual cycles, breast tenderness, or hair thinning. To stay on the safe side, routine blood tests are typically recommended to monitor potassium levels and other important health markers.
Most side effects tend to improve over time or with adjustments to the dosage. However, more serious concerns, like electrolyte imbalances, can arise if proper monitoring isn’t in place. That’s why ongoing medical oversight is key to ensuring the treatment remains both safe and effective over the long haul.
