How to treat hormonal acne with spironolactone in 2025: dermatologist and acne expert explains
What Are Anti-Androgen Therapies
Anti-androgen therapies are medications designed to reduce the effects of testosterone and dihydrotestosterone on the skin. These hormones can play a big role in triggering hormonal acne by increasing oil production in the sebaceous glands and causing inflammation.
These treatments work in two primary ways: either by blocking androgen receptors or by reducing the production of androgens. When androgens bind to receptors in sebaceous glands, they stimulate oil production and inflammation, which can lead to acne. Anti-androgen therapies interrupt this process, helping to reduce sebum production and promote clearer skin. This sets the stage for understanding how these therapies are applied in medical practice.
How They Work in Clinical Practice
In the U.S., anti-androgen therapies are prescribed based on the severity of hormonal symptoms and the specific needs of the patient. For example, topical clascoterone works by blocking androgen receptors directly on the skin, while oral spironolactone has a systemic effect throughout the body. Additionally, combined oral contraceptives work by suppressing ovarian androgen production and boosting levels of sex hormone–binding globulin, which lowers the amount of free androgens circulating in the bloodstream.
FDA Approval Status
The approval status of anti-androgen therapies differs depending on the medication. Clascoterone cream 1% (marketed as Winlevi) was approved by the FDA in August 2020 as the first topical anti-androgen specifically for acne treatment. Several combined oral contraceptives are also FDA-approved for treating acne in women. However, spironolactone is commonly used off-label for acne management in the U.S. Meanwhile, flutamide and cyproterone acetate are not FDA-approved for acne treatment, and cyproterone acetate is unavailable in the U.S. due to safety concerns. Understanding these distinctions is key to tailoring treatments for individual patients.
Typical Patient Profiles
Anti-androgen therapies are most often recommended for women dealing with moderate to severe hormonal acne, especially when other treatments haven’t worked or when there are clear signs of androgen excess, such as in polycystic ovary syndrome (PCOS). These women might also experience symptoms like irregular menstrual cycles or excessive facial hair. Screening for contraindications is a critical step before starting treatment.
For women seeking personalized hormonal care, providers like Oana Health offer science-based, customized treatment plans that often include anti-androgen therapies as part of a broader strategy to manage PCOS-related symptoms.
The effectiveness of these therapies is supported by clinical research. For instance, two phase 3 clinical trials involving 1,440 patients showed that clascoterone cream 1% significantly reduced acne lesion counts with minimal side effects, most of which were mild and comparable to those seen with a placebo. In areas where it is available, cyproterone acetate has been shown to improve symptoms in about 70% of patients with hirsutism and other androgen-driven skin conditions.
1. Spironolactone
Spironolactone stands out as a leading anti-androgen therapy for hormonal acne, thanks to its established safety and effectiveness over long-term use. Originally introduced as a blood pressure medication, this potassium-sparing diuretic has become a go-to treatment for women dealing with hormonal acne, especially those with symptoms linked to PCOS.
Safety Profile
Spironolactone is generally well-tolerated, with most side effects being mild. These include menstrual irregularities, breast tenderness, increased urination, and, occasionally, fatigue, dizziness, or headaches.
Although rare, serious side effects do exist and require attention. The most notable is hyperkalemia (elevated potassium levels), which, in severe cases, can disrupt heart rhythm.
For women of childbearing age, spironolactone carries a teratogenic risk, making reliable contraception a must during treatment.
FDA Approval Status
While spironolactone has not received FDA approval specifically for acne, it is frequently used off-label for this purpose. The American Academy of Dermatology endorses it for cases of resistant or hormonally driven acne.
Route of Administration
Spironolactone is taken as a daily tablet, offering a convenient option for long-term treatment. Dosages for acne typically range from 25 to 200 mg per day. Most dermatologists start with a lower dose, gradually increasing it based on the patient's response and tolerance. Taking the medication with food is recommended to reduce the chance of stomach upset.
For those seeking a tailored approach, Oana Health includes spironolactone in their hormonal care packages. Their "Metformin & Spironolactone pack" is available for $32 per month, complete with professional medical oversight. A satisfied patient, Margaret K., shared her experience:
"Thanks to Oana, my menstrual cycles are more regular, and my skin has never looked better!"
This ease of use and personalized care contributes to spironolactone's popularity as a first-line treatment for hormonal acne.
Monitoring Requirements
Regular monitoring is essential to ensure the safe and effective use of spironolactone. Initial tests typically include kidney function and electrolyte levels, with a focus on potassium. Follow-up tests are conducted about a month into treatment and then periodically, depending on individual risk factors and progress.
Patients should also be monitored for menstrual changes and blood pressure fluctuations, particularly if they have pre-existing cardiovascular conditions. During the first year, healthcare providers often schedule check-ins every three to six months to assess the treatment's effectiveness and manage any side effects.
It's worth noting that spironolactone is banned in athletic competitions unless a therapeutic use exemption is obtained. These monitoring practices reinforce its reputation as a safe and effective choice for managing hormonal acne.
2. Combined Oral Contraceptives with Anti-Androgenic Progestins
Combined oral contraceptives (COCs) with anti-androgenic progestins offer a dual benefit: they serve as effective contraception while addressing hormonal acne. These pills work by reducing ovarian androgen production and increasing levels of sex hormone-binding globulin, which helps lower free testosterone - two key factors in managing acne.
The most effective COCs for this purpose contain progestins like drospirenone, norgestimate, or norethindrone acetate. These ingredients target acne by reducing both sebum production and free testosterone levels. While generally safe, patient selection is crucial to minimize risks.
Safety Profile
COCs with anti-androgenic progestins are generally well-tolerated, with side effects such as nausea, breast tenderness, headaches, and breakthrough bleeding often improving after the first few months of use.
However, there are rare but serious risks. These include an increased chance of blood clots (venous thromboembolism), stroke, and high blood pressure. Women who smoke or are over 35 are at a higher risk for these complications. COCs are not recommended for individuals with a history of thromboembolic disorders, hormone-sensitive cancers, uncontrolled hypertension, or migraines with aura.
Additionally, women who are pregnant, breastfeeding, or over 35 and smoke should avoid using COCs due to heightened cardiovascular risks. Some progestins may cause fewer side effects like weight gain or mood changes, making them preferable for certain patients.
FDA Approval Status
Four COCs have received FDA approval specifically for acne treatment in females aged 15 and older who also need contraception. These include:
- Ethinyl estradiol/norgestimate (Ortho Tri-Cyclen)
- Ethinyl estradiol/norethindrone acetate/ferrous fumarate (Estrostep FE)
- Ethinyl estradiol/drospirenone (Yaz)
- Ethinyl estradiol/drospirenone/levomefolate (Beyaz)
This approval distinguishes these COCs from other anti-androgen therapies often prescribed off-label for acne. Clinical trials have shown these pills significantly reduce both inflammatory and non-inflammatory acne lesions.
Route of Administration
COCs are taken as a daily oral pill, with consistent timing each day ensuring stable hormone levels and optimal effectiveness. This straightforward dosing schedule makes them easier to integrate into daily routines, improving adherence compared to more complex treatments.
Prescriptions now tend to favor COCs with lower androgenic progestins and reduced estrogen doses. A dose of 20 μg of ethinyl estradiol is commonly chosen to minimize side effects while maintaining efficacy.
Monitoring Requirements
Before starting COCs, healthcare providers conduct a detailed medical history review and check blood pressure to rule out contraindications. Regular follow-ups, including annual visits, are standard to monitor blood pressure, review side effects, and reassess treatment effectiveness. Women with cardiovascular risk factors or other concerns may require more frequent check-ins.
COCs, like spironolactone, offer a tailored hormonal approach, providing both acne relief and contraception. Their dual functionality makes them an attractive option for women looking to address both concerns simultaneously.
3. Topical Clascoterone
Topical clascoterone has introduced a new approach to anti-androgen therapy for acne treatment. Clascoterone cream, 1%, stands out as the first and only topical androgen receptor inhibitor approved specifically for acne. It provides an alternative to oral medications by focusing solely on the skin. Its localized action targets androgen receptors in the skin, reducing sebum production and inflammation without affecting the rest of the body. Since the medication is quickly inactivated after application, the risk of systemic side effects is significantly minimized. This localized approach is a key difference compared to the broader, systemic effects of oral therapies.
Safety Profile
Clascoterone has shown a strong safety record for both male and female patients. In two phase 3 clinical trials (CB-03-01/25 and CB-03-01/26), the cream demonstrated a safety profile comparable to placebo, with most side effects being mild and temporary, such as redness, itching, or scaling as the skin adjusts. Importantly, no systemic side effects have been observed in studies, and serious adverse reactions are rare. There were no significant changes in reproductive hormones or lab parameters reported. This localized action significantly reduces the systemic risks often associated with oral anti-androgen treatments.
FDA Approval Status
The FDA has approved clascoterone cream, 1%, for treating acne vulgaris in patients aged 12 and older. While clinical trials also showed its safety and effectiveness in patients as young as 9 years old with facial acne vulgaris, the official approval currently applies to those 12 and older. This approval sets clascoterone apart from other anti-androgen treatments, which are often prescribed off-label for acne.
Route of Administration
After its approval, clascoterone is administered by applying the cream directly to clean, dry skin on acne-affected areas. Typically, this is done twice daily. This simple application method allows the medication to work exactly where it's needed while avoiding systemic exposure.
Monitoring Requirements
Routine monitoring isn’t usually necessary. Unlike oral anti-androgens, which often require regular lab tests to check for systemic side effects, clascoterone’s minimal absorption into the bloodstream eliminates the need for such tests. Healthcare providers may monitor for mild local skin reactions during the early stages of treatment and check on the treatment’s effectiveness and skin tolerance during follow-up visits.
The combination of ease of use, minimal side effects, and lack of intensive monitoring makes topical clascoterone an appealing choice for patients seeking effective anti-androgen therapy without the complexities of oral alternatives.

4. Flutamide
Flutamide offers a systemic approach to managing acne, but it comes with serious safety concerns that limit its use, especially in the United States.
Flutamide is a non-steroidal anti-androgen that works by blocking androgen receptors. This reduces androgen-driven sebum production, a key factor in acne development. At a dose of 250 mg/day, about 80% of patients experience improvement. However, its safety risks mean flutamide is typically reserved for off-label use in cases where other treatments have failed or are unsuitable.
Safety Concerns
Flutamide's safety profile raises significant red flags. The most alarming risk is hepatotoxicity, which can be fatal. This liver toxicity is influenced by both dosage and patient age, making it especially risky for certain groups. Other common side effects include gastrointestinal discomfort, hot flashes, breast tenderness, and reduced libido. Rare but severe conditions like hemolytic anemia and methemoglobinemia have also been reported. Additionally, flutamide is contraindicated for women who are pregnant or may become pregnant due to potential teratogenic effects and insufficient safety data.
FDA Approval Status
In the United States, flutamide is FDA-approved only for treating prostate cancer. Its use for acne or other androgen-related skin conditions is off-label and not recommended as a first-line option. Expert guidelines suggest flutamide should only be considered in carefully selected cases, with close monitoring and a thorough discussion of its risks with the patient.
Administration and Dosage
Flutamide is taken orally in tablet form. For acne treatment, doses ranging from 62.5 to 500 mg/day have been studied, with 250 mg/day showing an 80% improvement rate. However, its use demands strict safety monitoring due to the associated risks.
Monitoring Guidelines
Given the high risk of liver toxicity, baseline liver function tests (LFTs) are essential before starting flutamide. Monthly monitoring is required during the initial months of treatment, and the medication should be discontinued if liver enzyme levels rise significantly. Patients must be educated on the symptoms of liver damage and the importance of following the monitoring schedule. These stringent requirements underscore flutamide's lower safety profile compared to other anti-androgen therapies for acne.
5. Cyproterone Acetate
Cyproterone acetate holds the lowest position in our safety rankings due to its notable risks and the absence of FDA approval. While it can be effective in managing hormonal acne, the potential for severe side effects makes it a less favorable option. Here's a closer look at how it works and the clinical concerns it raises.
Cyproterone acetate is a synthetic steroid that acts as both an anti-androgen and a progestin. It works by blocking androgen receptors, reducing the influence of male hormones on the skin. This leads to lower sebum production, with European studies reporting up to a 70% improvement in severe acne and hirsutism. However, these benefits come with considerable safety concerns.
Safety Profile
The drug is associated with a range of side effects, from common ones like menstrual irregularities, breast tenderness, weight changes, mood swings, and decreased libido, to more severe risks. Serious complications include liver toxicity, blood clots (venous thromboembolism), and a heightened risk of developing meningioma with prolonged use. The risk of meningioma is particularly linked to doses of 10 mg or higher per day, prompting experts to caution against extended use at such levels. These risks significantly limit its appeal and place it firmly as the least safe option in this ranking.
FDA Approval Status
Cyproterone acetate has not been approved by the U.S. Food and Drug Administration (FDA) for any use, including acne treatment. This lack of approval stems from safety concerns, and as a result, the medication is not available for prescription in the United States. However, it is used in Europe and other regions where regulatory bodies have different evaluations of its risks and benefits.
Route of Administration
This medication is typically taken orally and is often combined with ethinylestradiol in a combined oral contraceptive pill. For acne and hirsutism, doses between 2–10 mg daily are common, while higher doses - up to 100 mg daily - may be prescribed for more severe androgen-dependent conditions. Due to these dosing regimens, careful monitoring is crucial to ensure safe use.
Monitoring Requirements
Close medical supervision is essential when using cyproterone acetate. Regular liver function tests are necessary to watch for hepatotoxicity, and healthcare providers must remain vigilant for signs of blood clots. For patients on long-term or high-dose treatments, periodic neurological evaluations are recommended to monitor for symptoms that could indicate meningioma. Frequent follow-ups are vital to catch any adverse effects early and manage them effectively.

The table underscores key differences in safety profiles. For instance, topical clascoterone stands out with minimal systemic risks and no routine monitoring requirements, making it a convenient option for many patients. In contrast, therapies like flutamide and cyproterone acetate demand regular liver function tests due to their potential for serious liver toxicity.
Pregnancy risks also vary significantly. Most oral therapies either require caution or are contraindicated, while topical clascoterone, with its localized action and minimal systemic absorption, presents a more favorable option, though its pregnancy safety profile remains uncertain.
These distinctions play a critical role in guiding healthcare providers to choose a therapy that aligns with both the patient's safety needs and treatment goals. By comparing these therapies, clinicians can weigh factors such as monitoring requirements, systemic risks, and long-term safety considerations to make informed decisions.
Long-Term Use Safety
When considering treatments for extended periods, safety becomes a critical factor. Long-term use requires consistent monitoring and personalized dosing to ensure effectiveness while minimizing risks.
Spironolactone has shown reliable safety for long-term use when monitored appropriately. A retrospective study involving 85 women taking 50–100 mg daily for up to two years found that nearly 67% experienced more than 50% improvement in their symptoms. Regular checks of blood pressure, potassium levels, and kidney function are essential. Common side effects, such as menstrual irregularities and breast tenderness, can usually be managed by adjusting the dose. Other anti-androgen therapies also benefit from tailored oversight to ensure safety over time.
Combined oral contraceptives with anti-androgenic progestins maintain their safety profiles even with prolonged use. However, regular monitoring of blood pressure and cardiovascular risk is crucial, especially for women over 35 or those who smoke.
Topical clascoterone stands out for its long-term safety due to minimal systemic absorption. Phase 3 trials reported no systemic side effects during extended use. This reduces the need for routine lab tests, with monitoring focused mainly on local skin reactions.
Systemic treatments like spironolactone require periodic blood tests and cardiovascular assessments. In contrast, topical therapies demand only localized monitoring. For women of childbearing age, effective contraception is vital when using systemic anti-androgens to avoid complications.
Long-term treatment plans should be tailored to the individual. Factors such as age, reproductive status, medical history, and personal preferences play a significant role in determining the best approach. For example, a 25-year-old woman with no cardiovascular risks may safely use combined oral contraceptives over the long term. Meanwhile, a 40-year-old with hypertension might find topical treatments more suitable. These considerations highlight the importance of working closely with a specialist to ensure safety and effectiveness.
Platforms like Oana Health simplify the process of ongoing safety monitoring. Their approach includes thorough medical history reviews, personalized treatment plans, and regular follow-ups.
