From the Guidelines
For a female patient with hirsutism that has improved with spironolactone treatment, the next step would be to inquire about her menstrual history, as menstrual irregularities are a common side effect of spironolactone, occurring in 15-30% of patients, and are dose-dependent, with a relative risk of 4.12 (95% CI 3.27-5.19) in women receiving a dose of 200mg/day compared to those receiving lower doses 1.
Importance of Menstrual History
Menstrual history is crucial in managing hirsutism, particularly in conditions like polycystic ovary syndrome (PCOS), which often presents with menstrual irregularities. Monitoring menstrual cycles helps assess the underlying hormonal status and evaluate the treatment's efficacy and potential side effects.
Associated Symptoms and Side Effects
While testosterone levels are important in the initial evaluation of hirsutism, once treatment has been initiated and shown effectiveness, monitoring for associated symptoms and potential side effects becomes more relevant. Spironolactone can cause various side effects, including breast tenderness, dizziness, nausea, headache, polyuria, and fatigue, and its use requires careful consideration, especially in patients with certain medical co-morbidities or those taking medications that may interact with spironolactone 1.
Comprehensive Management
Inquiring about menstrual history allows for comprehensive management of the patient's condition, focusing on both the visible symptoms of hirsutism and the underlying hormonal imbalances. This approach is supported by recent guidelines, which recommend considering spironolactone for acne treatment based on moderate certainty evidence from several studies, and emphasize the importance of monitoring for side effects and associated symptoms 1.
Key Considerations
When inquiring about menstrual history, it is essential to consider the potential impact of spironolactone on menstrual cycles and the importance of concomitant use of a combined oral contraceptive (COC) or hormonal intrauterine device to minimize the incidence of menstrual irregularities. Additionally, patients should be counseled to avoid becoming pregnant while on spironolactone due to its potential effects on fetal development 1.

Next Steps in Treatment
In a female patient with hirsutism who responded to treatment with spironolactone, the next steps in inquiry would involve:
- Assessing the patient's menstrual cycle regularity and fertility goals, as spironolactone can cause menstrual irregularities 2
- Evaluating the patient's response to treatment, including any changes in hair growth, acne, or other symptoms of hyperandrogenism 3, 4
- Monitoring for potential side effects of spironolactone, such as metrorrhagia, urticaria, or scalp hair loss 2
- Considering the addition of other treatments, such as combined oral contraceptives or anti-androgenic medications, to enhance the patient's response to treatment or to address any remaining symptoms 5
- Discussing the patient's plans for pregnancy, as spironolactone is not recommended during pregnancy due to the potential risk of abnormal fetal development 5
Potential Treatment Adjustments
Based on the patient's response to spironolactone, potential treatment adjustments could include:
- Adjusting the dosage of spironolactone to minimize side effects while maintaining its therapeutic effects 2, 4
- Adding a low-dose glucocorticoid, such as dexamethasone, to the treatment regimen for patients with glucocorticoid-sensitive hyperandrogenism 6
- Considering alternative anti-androgenic medications, such as cyproterone acetate or flutamide, for patients who do not respond adequately to spironolactone or who experience significant side effects 5
