Hirsutism, a condition causing excessive hair growth in areas like the face and chest, affects 5–10% of women in the U.S. It’s often linked to hormonal issues like PCOS. Androgen blockers, such as spironolactone, flutamide, finasteride, and eflornithine, are common treatments that help reduce hair growth by targeting male hormones. Results generally take 3–6 months, but these medications come with potential side effects, ranging from mild (irregular periods, nausea, fatigue) to severe (liver toxicity, electrolyte imbalances). Regular monitoring and professional guidance are critical for safe use. Platforms like Oana Health offer convenient telehealth services for personalized care, including prescriptions and home delivery.
Common Androgen Blockers for Hirsutism
Managing hirsutism often involves medications that target androgen levels, either by reducing them or blocking their effects. These treatments can significantly slow unwanted hair growth.
It's important to note that all antiandrogen medications carry a risk of interfering with normal male fetal development. For women of reproductive age, using reliable contraception while on these treatments is essential.
Spironolactone
Spironolactone is one of the most widely prescribed treatments for hirsutism in the United States. It works by blocking androgen receptors and decreasing the body's response to testosterone and related hormones, while also acting as a diuretic.
This medication is available in both oral and topical forms. The oral version is typically started at a dose of 50–100 mg per day, with many patients finding 100 mg daily to be the most effective. Studies have shown that a daily dose of 100 mg of spironolactone outperforms finasteride (5 mg daily) after nine months of treatment. Another clinical trial confirmed spironolactone's superior results over finasteride after one year of use.
For those who experience side effects from the oral form or prefer a localized option, topical spironolactone is a viable alternative. It can be applied directly to areas with unwanted hair growth, potentially reducing systemic side effects while maintaining effectiveness. However, results with spironolactone, whether oral or topical, typically take 6–8 months to become noticeable. While the treatment can thin terminal hairs, it does not restore them to their original vellus hair state.
Flutamide and Finasteride
Flutamide and finasteride offer different mechanisms for addressing androgen-related hair growth. Flutamide directly blocks androgen receptors, while finasteride inhibits 5-alpha reductase, the enzyme responsible for converting testosterone into the more potent androgen, dihydrotestosterone (DHT).
Finasteride, taken at 5 mg daily, can produce results similar to spironolactone. However, research often points to spironolactone as the more effective option.
Cyproterone Acetate and Eflornithine
Cyproterone acetate combines antiandrogen properties with progestational activity. Although it isn't available as a standalone medication in the United States, it is often included in certain birth control pills internationally. These pills provide both contraceptive benefits and antiandrogen effects.
Eflornithine offers a different approach as a topical treatment specifically for facial hair. Available as a 13.9% prescription cream, it works by inhibiting an enzyme called ornithine decarboxylase, which is essential for hair follicle function. Unlike systemic treatments, eflornithine acts only on the area where it is applied, making it ideal for targeting facial hair without affecting the body's overall hormone levels. The cream is applied twice daily, and most users notice improvements within 6 to 8 weeks. However, it primarily slows hair growth rather than removing it permanently.
For those seeking personalized care, Oana Health provides prescriptions for spironolactone (both oral and topical) and eflornithine through their telehealth platform. Licensed medical professionals assess your health history to recommend the most suitable treatment for your specific needs.
Side Effects and Safety Information
When considering treatment options for hirsutism, it's important to understand the potential side effects of androgen blockers. The risks can vary depending on the specific medication and individual health factors.
Common Side Effects
Systemic androgen blockers often lead to menstrual changes. These may include lighter or heavier periods, as well as shifts in cycle timing. For instance, spironolactone is known to cause irregular menstruation, especially during the early stages of treatment.
Mood changes, such as mood swings or irritability, are another frequent side effect. Medications like cyproterone acetate, which has both antiandrogenic and progestational properties, may be linked to more noticeable mood variations.
Skin and hair changes are also common. Spironolactone might cause dryness of the skin or alter the texture of scalp hair, while eflornithine cream may result in localized irritation, redness, or a burning sensation.
Other side effects include nausea, stomach upset, and changes in appetite, which are often more pronounced when starting treatment. Taking the medication with food can sometimes alleviate these issues.
Fatigue and dizziness may occur, particularly with spironolactone, due to its diuretic effects, which can lead to dehydration or electrolyte imbalances. Some individuals may also experience breast tenderness or changes in breast size.
It's essential to confirm the use of reliable contraception as advised by your healthcare provider during treatment.
While these side effects are usually manageable, there are some rare and serious risks that require immediate attention.
Serious or Rare Side Effects
Certain rare side effects demand prompt medical evaluation. For example, flutamide can impact liver function, potentially causing elevated liver enzymes or, in rare cases, severe liver toxicity. Regular blood tests to monitor liver health are crucial when using this medication.
Although mild mood changes are common, severe psychological effects - such as significant depression or suicidal thoughts - should be addressed immediately to assess whether treatment modifications are necessary.
Spironolactone may also cause electrolyte imbalances, particularly hyperkalemia. This is a greater concern for individuals with preexisting kidney conditions or those taking medications that influence potassium levels.
Severe allergic reactions, though rare, are possible with any medication. If you experience symptoms like difficulty breathing, a severe rash, or swelling of the face, lips, or throat, seek emergency medical care without delay.
Below is a table summarizing the safety considerations for these medications.
Medication Safety Comparison Table
| Medication | Common Side Effects | Serious Risks | Monitoring Required | Special Considerations |
|---|---|---|---|---|
| Spironolactone | Irregular periods, dizziness, fatigue | Hyperkalemia, severe dehydration | Blood pressure, electrolytes, kidney function | Diuretic effects; avoid high-potassium foods |
| Finasteride | Decreased libido, mood changes | None widely documented at therapeutic doses | Periodic mental health monitoring if needed | Contraindicated in pregnancy; use reliable contraception |
| Flutamide | Nausea, fatigue, mood changes | Severe liver toxicity | Liver enzymes every 4–6 weeks | High risk of liver damage; discontinue if issues arise |
| Cyproterone Acetate | Weight gain, mood swings, breast changes | Blood clots, liver abnormalities | Liver function, blood clotting factors | Not available as a standalone option in the US |
| Eflornithine | Skin irritation, redness, burning | Severe allergic reactions (rare) | Visual skin assessment | Topically applied; localized effects |
The likelihood and intensity of side effects depend on factors such as the medication dose, length of treatment, and individual health conditions. With proper monitoring, most people tolerate these treatments well. However, understanding these risks can help you recognize when to consult a healthcare provider.
How to Manage Side Effects
Managing side effects often involves adjusting medication doses, making lifestyle tweaks, and keeping up with regular check-ins. Staying in close contact with your healthcare provider is key to fine-tuning your treatment plan and minimizing discomfort.
Monitoring and Dose Adjustments
Regular follow-ups with your healthcare provider are crucial. These visits allow them to track any side effects and make timely adjustments to your dosage. Pairing these adjustments with simple lifestyle changes can also help ease symptoms.
Practical Tips for Comfort
If you’re dealing with nausea or an upset stomach, try taking spironolactone with or right after a meal to lessen digestive irritation. During the first few weeks of treatment, steering clear of rich or spicy foods can also help reduce stomach discomfort.

When to Contact Your Doctor
It's important to know when to reach out to your doctor, especially when dealing with symptoms that may require immediate medical attention. Understanding the warning signs can help you take timely action.
Warning Signs to Watch For
Even with careful monitoring and dose adjustments, certain symptoms demand prompt professional care.
- Severe digestive issues: Persistent vomiting or intense abdominal pain shouldn't be ignored. If you notice signs of dehydration, like dizziness or dark urine, contact your doctor right away. These could point to serious complications that need urgent attention.
- Liver-related symptoms: Watch for yellowing of the skin or eyes, dark urine, or pale stools. These signs may indicate liver stress, particularly if you're taking specific androgen blockers, and require immediate evaluation.
- Heart-related symptoms: Irregular heartbeats, chest pain, or severe dizziness could signal an electrolyte imbalance, especially if you're on spironolactone. Seek medical advice promptly.
- Mental health concerns: Severe mood swings, depression, anxiety, or thoughts of self-harm are just as important to address as physical symptoms. Reach out to a healthcare provider immediately if you experience these.
- Allergic reactions: Allergies can develop even after weeks or months of taking a medication. If you notice skin rashes, hives, swelling in your face or throat, or difficulty breathing, seek emergency medical care.
Other Treatment Options
If side effects persist or if your current treatment isn't effective, there are alternative strategies to consider.
- Topical treatments: Prescription creams like eflornithine target hair follicles directly to slow growth. These are often a gentler option with fewer systemic side effects, making them particularly useful for facial hair.
- Combination therapies: Using a mix of low-dose medications can enhance results while minimizing side effects. Oana Health offers personalized treatment plans that combine approaches tailored to your needs, balancing effectiveness with comfort.
- Hair removal methods: Options like laser hair removal, electrolysis, or professional waxing can deliver immediate results. These methods work well alongside prescription treatments to manage hirsutism comprehensively.
- Hormonal treatments: Depending on your condition, addressing hormonal imbalances may be key. For example, if you have PCOS, treatments that target insulin resistance or other underlying hormonal issues may be more effective.

FAQs
What are the possible long-term side effects of androgen blockers for hirsutism, and how can they be managed?
Long-term use of androgen blockers for treating hirsutism can sometimes come with side effects. One of the more concerning issues is decreased bone density, which could heighten the risk of osteoporosis and fractures. Other possible side effects include liver strain and altered cholesterol levels. The extent of these risks often depends on the specific medication used and individual health factors.
To help counteract these side effects, healthcare providers often recommend regular bone density scans and calcium and vitamin D supplements. Adding weight-bearing exercises to your routine can also support bone strength. For liver and overall metabolic health, periodic blood tests and ongoing monitoring by a medical professional are key. If the side effects become too challenging, your doctor may tweak your treatment plan or suggest alternative therapies.
For those seeking personalized care, services like Oana Health offer prescription-based treatments and support for hormonal health and PCOS, delivered right to your doorstep.
What’s the difference between topical and oral spironolactone for treating hirsutism?
Topical spironolactone is applied directly to the skin, targeting unwanted hair growth at the source. Because it doesn't significantly enter the bloodstream, it typically avoids causing systemic side effects, such as dizziness or fatigue. In contrast, oral spironolactone works throughout the body to address hormonal imbalances, making it a stronger option for more severe cases of hirsutism. However, this broader action can also increase the likelihood of side effects.
Both treatments can be effective, but the right choice depends on factors like the severity of your symptoms, your tolerance for side effects, and your personal preferences. A licensed healthcare provider can guide you in selecting the most suitable option for your situation.
What serious side effects can androgen blockers cause, and when should I seek medical attention?
While androgen blockers are generally considered safe when taken as prescribed, there are potential risks you should be aware of. Reach out to your healthcare provider right away if you notice severe allergic reactions, such as trouble breathing, swelling in your face or throat, or hives. Watch for signs of liver issues too, like yellowing of the skin or eyes, unusually dark urine, or persistent nausea.
Other serious symptoms to look out for include persistent calf pain, chest discomfort, sudden swelling, or neurological issues like seizures or extreme dizziness. These could signal blood clots or other complications that need immediate attention. When in doubt, don’t hesitate - consult a medical professional as soon as possible.
