Hirsutism, or excess hair growth in women, often stems from elevated androgen levels or increased hair follicle sensitivity. Anti-androgen medications target these hormonal imbalances, providing a medical solution for managing symptoms. Common treatments include:
- Spironolactone: Blocks androgen receptors, reduces testosterone, and slows hair growth. Results take 6–12 months, with side effects like menstrual irregularities and potential birth defects.
- Eflornithine (Topical): Slows facial hair growth by blocking specific enzymes. Works locally with fewer systemic effects but requires consistent use.
- Finasteride: Inhibits androgen production. Comparable to spironolactone but with fewer side effects.
- Flutamide: Effective but carries significant risks, like liver damage.
- Cyproterone Acetate: Available outside the U.S., reduces androgen levels and receptor activity.
Emerging therapies like SPIOMET and topical options like Fluridil show promise for future treatment. For personalized care, telehealth platforms offer expert guidance and convenient access to these treatments.

Spironolactone: Oral Anti-Androgen Treatment
How Spironolactone Works
Spironolactone stands out as a key player in the fight against hirsutism, offering a multi-faceted approach to reducing androgen effects. It works by lowering testosterone levels through several mechanisms: blocking testosterone synthesis, enhancing its clearance from the body, and preventing it from binding to receptors. This reduces the androgen-driven stimulation of hair follicles. As noted by Clinics in Endocrinology and Metabolism:
"Spironolactone generally lowers the plasma testosterone by altering its formation and metabolism as well as by decreasing its blood production rate; the medication also contributes to increase the peripheral conversion of testosterone to oestradiol. A major action is that spironolactone inhibits androgen binding to receptor molecules in the cytosol or the nucleus of target tissues such as the skin."
Additionally, spironolactone promotes the conversion of testosterone to estradiol and reduces the activity of sebocytes, which are responsible for oil production in the skin. This combination of actions makes it an effective option for managing androgen-related symptoms.
Dosage, Results, and Side Effects
The typical dosage of spironolactone ranges from 50 to 200 mg per day, with noticeable improvements often taking 6–12 months. Research supports this timeline, as one study highlights:
"With current systemic therapies for hirsutism, 6 months to a year of therapy is usually required before results are noticeable."
Long-term data reveals that 80% of patients experience good to very good outcomes over three to four years. However, the treatment isn't without challenges. In one study, 68% of women starting on 100 mg twice daily either reduced their dosage or stopped treatment altogether due to adverse effects. Furthermore, 56% reported irregular uterine bleeding on 14-day cycles. Other commonly reported side effects include menstrual irregularities, breast tenderness, fatigue, dizziness, and headaches.
Patients are advised to avoid potassium-rich foods and low-sodium salt substitutes, as these can lead to dangerously high potassium levels. These considerations highlight the need for individualized treatment plans to balance effectiveness and tolerability.
Safety Considerations
Spironolactone carries certain safety risks that require careful monitoring. One of the most serious concerns is its potential to cause birth defects, making effective contraception essential for women of childbearing age during treatment. Regular blood tests to monitor electrolytes and kidney function are also critical.
Staying hydrated is important to avoid dehydration, and taking the medication with food can help reduce gastrointestinal discomfort. Patients should be on the lookout for serious symptoms, such as muscle weakness, irregular heartbeat, or confusion, which may signal dangerous electrolyte imbalances. Additionally, while spironolactone has been linked to tumor development in animal studies, its implications for humans remain uncertain.
These safety considerations underscore the importance of a personalized approach when using spironolactone as part of a hirsutism treatment plan. Regular follow-ups and open communication between patients and healthcare providers are key to managing risks and achieving the best possible outcomes.
Eflornithine: Topical Treatment for Facial Hair
What is Eflornithine and How Does it Work?
Eflornithine cream (previously sold as Vaniqa) is a topical solution designed to slow down facial hair growth. Unlike oral anti-androgens that work throughout the body, this cream takes a more localized approach. It works by blocking the enzyme ornithine decarboxylase (ODC), which plays a key role in hair follicle activity. This doesn’t remove hair entirely but reduces the rate of growth. Plus, with less than 1% of the cream absorbed into the body, it focuses on the application area and minimizes systemic effects.
Application and Expected Results
To use, apply a thin layer of the cream to clean, dry skin on the face twice a day, keeping an 8-hour gap between applications. If you’ve just removed hair, wait 5 minutes before applying the cream, and allow it to absorb for at least 4 hours before washing or using makeup.
Clinical studies reveal that about 58% of women notice improvements within 24 weeks, with visible changes often appearing between 4 to 8 weeks. However, if no progress is seen after 6 months, it’s a good idea to consult with a healthcare provider. Keep in mind, once you stop using the cream, hair growth typically returns to its original rate within 8 weeks. Some users may experience mild side effects like acne, razor bumps, or slight stinging.
Combining Eflornithine with Other Therapies
Eflornithine works well alongside other treatments, such as systemic medications like Spironolactone, to manage unwanted hair. Since it only slows hair growth rather than removing it, combining it with cosmetic methods like shaving, waxing, or plucking can enhance results. For a personalized approach, telehealth platforms like Oana Health offer consultations and quick prescription deliveries, making it easier to include eflornithine in your hirsutism treatment plan.
Other Anti-Androgen Medications and New Options
Additional Medication Options
There are several other anti-androgen medications available to treat hirsutism, each working in unique ways to manage unwanted hair growth.
Finasteride blocks the enzyme 5‑alpha‑reductase, which converts testosterone into dihydrotestosterone (DHT) - a more potent androgen that promotes hair growth. Studies indicate that finasteride performs on par with spironolactone, making it a solid alternative for those who experience side effects from spironolactone.
Flutamide, a selective anti-androgen, has been found effective in reducing hair growth. However, it comes with serious risks, including the potential for fatal hepatitis, and is generally more expensive.
A 12-month study revealed that combination therapy reduced hirsutism scores by 49%, while flutamide and finasteride alone resulted in reductions of 45% and 32%, respectively.
Cyproterone acetate (CPA) is another effective option for managing hirsutism. Unfortunately, CPA is not available in the United States, limiting its use for patients in the country.
These medications work by targeting androgens in different ways - whether by blocking androgen receptors, reducing androgen production, or inhibiting 5‑alpha‑reductase. This variety allows healthcare providers to customize treatments based on a patient’s specific needs.
Meanwhile, new therapies are being explored to expand treatment options further.
New Therapies for Hirsutism
The field of hirsutism treatment is advancing, with researchers investigating new combination therapies and compounds that aim to deliver better results with fewer side effects.
SPIOMET is a promising new approach currently under study. This combination therapy includes spironolactone, pioglitazone, and metformin, targeting multiple aspects of polycystic ovary syndrome (PCOS) and hirsutism. The SPIOMET4HEALTH trial - a multicenter, randomized, double-blind, placebo-controlled phase II study - is testing the safety and effectiveness of this treatment in adolescent girls and young women with PCOS. The trial plans to enroll 364 participants across seven European clinical centers. Early pilot studies suggest SPIOMET outperforms oral contraceptives in normalizing PCOS symptoms, improving ovulation rates, and reducing hepato-visceral fat.
Fluridil is another exciting development, offering a topical anti-androgen therapy. Early clinical research indicates that fluridil could be a safe and effective option for managing hirsutism and other hyperandrogenic skin conditions.
"Newer therapies directed at inhibition of 5‐alpha‐reductase or blockade of the androgen receptor may improve the ability to treat patients."
– George T Griffing, MD, Professor Emeritus of Medicine, St. Louis University School of Medicine
Additionally, plant-based treatments are being explored as supplemental options for managing hirsutism.

Comparing Anti-Androgen Treatments
Anti-Androgen Medication Comparison Table
When choosing an anti-androgen therapy for hirsutism, understanding the differences between available treatments is key. Each medication works differently, comes with its own set of benefits and side effects, and is suited to specific needs. Below is a quick comparison to help guide your decision-making.
| Medication | Mechanism | Primary Use | Results | Side Effects | Safety Considerations | Approximate Cost |
|---|---|---|---|---|---|---|
| Spironolactone | Prevents androgens from binding to receptors | Hirsutism, acne | Modest improvement after 6+ months; ~19% reduction in hair growth score | Menstrual irregularities | Requires contraception to avoid birth defects | $17–$25/month for 100mg tablets |
| Eflornithine (Topical) | Slows new hair growth | Facial hair in women | Reduces new growth (~30% improvement); does not remove existing hair | Skin irritation at application site | No need for contraception | $64 per 30g tube (lasts 3–5 months for upper lip) |
| Flutamide | Blocks androgen receptors directly | Severe hirsutism, acne | Up to 40% reduction in hair growth; 80% acne improvement in 3 months | Fewer side effects than spironolactone; risk of liver damage | Requires liver function monitoring | Higher cost than spironolactone |
| Finasteride | Inhibits the 5-alpha reductase enzyme | Hirsutism, hair loss | Comparable to spironolactone; ~17% reduction in hair growth score | Fewer side effects than receptor blockers | Contraception needed to prevent birth defects | Similar pricing to spironolactone |
| Cyproterone Acetate | Blocks receptors and reduces hormone production | Moderate to severe hirsutism | Similar to spironolactone when combined with estradiol | Weight gain, fatigue, depression, breast symptoms | Not available in the U.S. | N/A in U.S. market |
This table provides a snapshot to help evaluate which medication might work best for you. While most treatments show similar overall effectiveness in reducing hair growth, the side effects and safety measures often determine the best fit for an individual.
Oral medications like spironolactone and finasteride are systemic, making them ideal for managing more widespread hirsutism. On the other hand, eflornithine is a topical option that specifically targets facial hair without affecting the rest of the body.
For mild facial hirsutism, eflornithine alone may suffice. Pairing it with laser therapy can boost success rates to as much as 95%. For moderate to severe cases, oral anti-androgens such as spironolactone - known for its established track record - are often the go-to choice.
Keep in mind that results take time. It typically takes 6 to 8 months to see noticeable changes, with maximum benefits appearing after up to 2 years. On average, these treatments reduce hair growth scores by about 20%, though some, like flutamide, can achieve reductions of up to 40%. Cost is another factor: spironolactone is among the more affordable options at $17–$25 per month, while eflornithine involves a higher upfront cost but lasts several months per tube.

Personalized Treatment and Telehealth Solutions
The Importance of Individualized Care
Hirsutism presents itself in various ways, making a one-size-fits-all approach ineffective. Treatment decisions depend on factors like the severity of symptoms, underlying causes, and whether the patient has specific reproductive goals. Since many women with hirsutism also have PCOS, managing this condition often involves addressing multiple hormonal imbalances at once.
The spectrum of hirsutism ranges from mild facial hair growth to more pronounced patterns on areas like the chest, back, and abdomen. Regardless of how subtle the symptoms may seem, healthcare providers should evaluate concerns about unwanted hair growth thoroughly. A patient-centered approach that combines medical treatments with cosmetic hair removal options often delivers the best results. This kind of individualized care not only addresses the root causes but also improves quality of life, offering a pathway to more accessible and specialized care through telehealth solutions.

FAQs
What’s the difference between oral and topical anti-androgen treatments for hirsutism?
Oral anti-androgen medications, like spironolactone, help reduce androgen levels throughout the body. These are commonly prescribed for moderate to severe cases of hirsutism. However, they can lead to side effects such as hormonal shifts, irregular menstrual cycles, and potential risks during pregnancy. Because of this, using contraception alongside these medications is often recommended.
For a more localized approach, topical treatments like eflornithine are applied directly to the skin to manage hair growth in specific areas. These treatments generally have fewer body-wide side effects, making them a suitable option for mild or localized hirsutism. That said, they may not be as effective for more extensive cases.
Choosing the right treatment depends on how severe your symptoms are, your preferences, and how well you handle potential side effects. Be sure to consult a licensed healthcare provider to find the best solution for your situation.
What are the benefits of new treatments like SPIOMET and Fluridil for managing hirsutism compared to traditional options?
Emerging treatments like SPIOMET and Fluridil are gaining attention as potential alternatives to conventional therapies for hirsutism. SPIOMET, a combination of spironolactone, pioglitazone, and metformin, has shown in early studies to potentially reduce hirsutism symptoms more effectively than metformin alone. On the other hand, Fluridil, a topical antiandrogen, has been noted for its ability to significantly reduce hair growth and improve the hair growth cycle, making it a non-invasive option worth considering.
While traditional treatments such as spironolactone and eflornithine remain effective, these newer options could offer additional advantages, including better outcomes and fewer systemic side effects. As research progresses, these therapies might play a key role in creating more tailored approaches to managing hirsutism.
What precautions should I take when using spironolactone to treat hirsutism?
When using spironolactone to manage hirsutism, keeping an eye on your potassium levels is crucial. This medication can raise potassium levels in the blood, which might pose risks - especially if you have kidney or liver issues. To minimize these risks, it's best to avoid potassium supplements and limit foods rich in potassium, such as bananas, oranges, and spinach.
It's also important to note that spironolactone is not safe during pregnancy due to potential harm to fetal development. While on this medication, routine blood tests are typically recommended to monitor potassium levels and check kidney function. Always stick to your healthcare provider's guidance and bring up any questions or concerns you have throughout your treatment.
