Spironolactone is a medication that helps improve insulin resistance, particularly in women with PCOS and metabolic syndrome. It works by targeting three key pathways: blocking aldosterone, improving glucose uptake in fat and muscle, and reducing inflammation. These actions help break the cycle of insulin resistance and hormonal imbalances, which often lead to symptoms like acne, unwanted hair, and menstrual irregularities.
Key Takeaways:
- How it works: Blocks aldosterone, enhances glucose transport, and reduces inflammation.
- Who benefits: Women with PCOS (affects 65–70% of patients) and individuals with metabolic syndrome.
- Combination therapy: Works best when paired with metformin for improved insulin sensitivity.
- Safety: Regular monitoring of potassium levels and kidney function is essential.
Spironolactone not only addresses physical symptoms but targets the root causes of insulin resistance, offering a comprehensive approach to metabolic health.

How Spironolactone Improves Insulin Resistance
Spironolactone helps combat insulin resistance through three main pathways: blocking aldosterone binding, improving insulin activity in fat and muscle, and reducing inflammation. Let’s break down how each of these mechanisms works.
Blocking Aldosterone Effects
Increased levels of aldosterone, often seen in obesity, can worsen insulin resistance. When aldosterone binds to its receptors, it triggers the production of reactive oxygen species (ROS), which degrade IRS1 and IRS2 proteins - key players in insulin signaling. Spironolactone steps in by blocking this binding, effectively disrupting the harmful chain reaction. For instance, research involving obese individuals showed that spironolactone not only blocked aldosterone binding but also lowered systolic blood pressure.
Improving Insulin Function in Fat and Muscle
Fat and muscle tissues are vital for glucose uptake, making them critical targets for managing insulin resistance. Spironolactone promotes glucose absorption by boosting the activity of GLUT4, a glucose transporter protein. In a study on transgenic Ren2 rats, a low dose of spironolactone (0.24 mg/day via time-release pellets over 21 days) improved insulin signaling in the soleus muscle and enhanced overall insulin sensitivity. This was achieved by reducing NADPH oxidase activity and ROS production, even without affecting blood pressure. Similarly, in mice fed a Western diet, spironolactone improved both insulin signaling and glucose tolerance.
Reducing Inflammation and Oxidative Stress
Chronic inflammation and oxidative stress are major drivers of insulin resistance. Spironolactone has been shown to lower ROS production and regulate inflammatory markers associated with metabolic disorders. For example, in a letrozole-induced rat model of PCOS, low-dose spironolactone (0.25 mg/kg over 21 days) reduced inflammation, oxidative stress, and cell death in fat tissue. This included lowering markers like NF-kB, TNF-α, and IL-6. Additionally, studies on diabetic mice revealed that spironolactone boosted the activity of antioxidant enzymes such as superoxide dismutase-1 and catalase, enhancing the body’s defense against free radicals. The drug also improved glucose and lipid metabolism by reducing liver fat buildup, inflammation, and excessive gluconeogenesis caused by high-fat and high-fructose diets.
Research on Spironolactone for Insulin Resistance
Clinical studies highlight spironolactone's potential in addressing insulin resistance, particularly in women with PCOS and individuals with metabolic syndrome. The research shows encouraging results for improving glucose metabolism and insulin sensitivity.
PCOS Study Results
From 2014 to 2016, a study at the Third Affiliated Hospital of Guangzhou Medical University examined 189 women with PCOS. Participants were divided into three groups: those receiving metformin alone (1,500 mg/day), spironolactone alone (40 mg/day), and a combination of both medications. After 12 weeks, the combination therapy showed the most significant improvement, with the lowest HOMA-IR score at 1.71 ± 0.91. This was compared to 1.92 ± 1.07 for metformin alone and 2.38 ± 1.14 for spironolactone alone.
"Both metformin and spironolactone decreased HOMA-IR in patients with PCOS but without differences between the two monotherapies. The combined therapy decreased HOMA-IR to a greater extent than monotherapy." - Tao Long et al.
Additionally, a meta-analysis of six randomized controlled trials revealed that combining metformin and spironolactone over six months led to reductions in BMI, testosterone levels, fasting glucose, and HOMA-IR. These findings underscore the potential of spironolactone in combination therapies for managing PCOS symptoms and related metabolic issues.
Metabolic Syndrome Research Findings
Spironolactone's benefits extend beyond PCOS, showing promise in reducing insulin resistance in metabolic syndrome. For instance, in a study involving 17 patients with untreated stage I hypertension, those treated with chlorthalidone alone experienced improved blood pressure (from 135±3/84±2 to 124±2/78±2 mm Hg). However, this came with adverse effects, including higher fasting plasma glucose, increased insulin levels, and elevated HOMA-IR, alongside a reduction in QUICKI. When spironolactone was added to the treatment, HOMA-IR and serum insulin levels returned to baseline, significantly improving insulin sensitivity compared to chlorthalidone alone.
The study also identified strong links between sympathetic nervous system activity and glucose changes, with correlation coefficients of r = 0.64 (p = 0.01) for bursts per minute and r = 0.76 (p = 0.001) for bursts per 100 RR intervals. These findings highlight spironolactone's role in counteracting aldosterone's effects and enhancing insulin action.
Comparison Studies with Other Treatments
Direct comparisons provide further insights into spironolactone's effectiveness. The Guangzhou Medical University study noted no significant differences between metformin and spironolactone monotherapies in improving glucose metabolism or reducing total testosterone levels. However, spironolactone outperformed metformin in addressing hirsutism, menstrual irregularities, and other hormonal imbalances in women with PCOS.
A systematic review of placebo-controlled trials found that spironolactone increased HbA1c by 0.16% (95% confidence interval, 0.02 to 0.30). While spironolactone can improve short-term insulin sensitivity (measured by HOMA-IR), this suggests that long-term glucose control may require careful monitoring. Combining spironolactone with other treatments often yields the best results, emphasizing its role as a complementary therapy for managing PCOS and metabolic health challenges effectively.

Using Spironolactone for Insulin Resistance
When using spironolactone to address insulin resistance, it’s crucial to understand how the treatment works, what to expect, and how to use it safely. Healthcare providers rely on established protocols for dosing, monitoring, and combining therapies to achieve the best outcomes while minimizing potential risks.
Dosage and Timeline
Most treatments start with a daily dose of 25 mg, which is adjusted based on how the patient responds. The time it takes to see results can vary, depending on factors like the severity of insulin resistance, other treatments being used, and any lifestyle changes implemented. Any adjustments to the dosage should always be made under medical supervision.
Safety Monitoring Requirements
Once the dosage is determined, regular monitoring becomes essential. Blood tests are used to check key markers, such as potassium and sodium levels, as well as kidney function. This is particularly important because hyperkalemia (high potassium levels) is a common side effect. Healthcare providers also monitor blood pressure, urine output, and any swelling. While increased urination is common at the start of treatment, excessive urination can lead to dehydration, low blood pressure, or kidney issues.
Follow-up appointments are typically more frequent during the first few months of treatment. Over time, they may occur at regular intervals, with closer monitoring for patients at higher risk of complications. Dietary adjustments can also help reduce risks. For example, people prone to hyperkalemia should limit foods high in potassium, such as bananas, oranges, avocados, potatoes, beans, and certain salt substitutes. Additionally, patients should avoid NSAIDs unless prescribed and should contact their healthcare provider if they experience symptoms like diarrhea, vomiting, or signs of infection (e.g., fever and sweating).
Combining with Other Treatments
Combining spironolactone with other medications can improve outcomes. Research shows that pairing spironolactone with metformin enhances insulin sensitivity more effectively than using either medication alone, without increasing adverse effects. For instance, in a 12-week study involving 189 women with PCOS, the group receiving both medications achieved a HOMA-IR score of 1.71 ± 0.91, compared to 1.92 ± 1.07 for metformin alone and 2.38 ± 1.14 for spironolactone alone.
This combination works well because the two medications target insulin resistance through different mechanisms. Spironolactone blocks androgen receptors and reduces inflammation by interfering with aldosterone’s effects on mineralocorticoid receptors. Meanwhile, metformin improves insulin sensitivity through its own pathways.
Of course, lifestyle modifications are a key part of treatment.

Conclusion: Spironolactone's Role in Metabolic Health
Spironolactone provides a multi-faceted approach to tackling insulin resistance by addressing key pathways linked to metabolic dysfunction. As highlighted earlier, its ability to block aldosterone and reduce inflammation makes it particularly helpful for women with PCOS, where hormonal imbalances and insulin resistance often overlap.
Clinical research backs its effectiveness across various patient groups. For instance, a 2014 study in the International Journal of Cardiology demonstrated that a daily dose of 25 mg of spironolactone significantly improved insulin sensitivity in patients with chronic heart failure over 16 weeks. The study showed reductions in plasma insulin levels and HOMA-IR scores, alongside decreases in inflammatory markers like TNF-α, IL-6, and MCP-1 - changes that aligned with better insulin resistance outcomes.
For women with PCOS, combining spironolactone with metformin offers additional benefits. Studies reveal that pairing a low dose of spironolactone (25 mg/day) with metformin (1,700 mg/day) results in greater reductions in both clinical and biochemical signs of hyperandrogenism compared to metformin alone. This combination effectively tackles the dual challenges of insulin resistance and excess androgen production.
Safe and effective use of spironolactone requires a tailored approach. Starting with a low dose, such as 25 mg per day, allows healthcare providers to monitor tolerance and adjust treatment as needed, particularly by keeping an eye on potassium levels. When paired with lifestyle changes like a balanced diet and regular exercise, spironolactone becomes part of a well-rounded strategy for improving metabolic health.
Accessing this personalized care has become easier with telehealth platforms like Oana Health, which provide affordable, specialized hormonal treatments. These services make it simple to adjust treatment plans based on individual responses, removing traditional barriers and supporting comprehensive metabolic care.
FAQs
How does spironolactone help improve insulin resistance in women with PCOS or metabolic syndrome?
Spironolactone plays a role in addressing insulin resistance in women with PCOS or metabolic syndrome by tackling key hormonal issues.
