oral contraceptive + spironolactone

A combination therapy consisting of an oral contraceptive pill and spironolactone, primarily used to treat conditions like hirsutism, acne, and polycystic ovary syndrome (PCOS). This combination leverages the complementary mechanisms of both medications to provide enhanced efficacy compared to either agent alone. Oral contraceptives work by suppressing gonadotropin-mediated ovarian androgen secretion and increasing sex hormone binding globulin (SHBG) in plasma, which reduces free, biologically active androgens in circulation[5]. Spironolactone functions as an anti-androgen by blocking androgen receptors[5]. When combined, these medications provide a synergistic effect in treating androgen-related conditions. Clinical studies have demonstrated that this combination is effective for treating hirsutism, with significant improvement observed in both objective and subjective assessments after 6 months of treatment[1][5]. The combination has also shown superior efficacy compared to metformin for treating PCOS symptoms, with similar safety profiles and neutral effects on cardiometabolic risk factors[2][3]. For acne treatment, the combination works well, with spironolactone's anti-androgen properties complementing the hormonal regulation provided by oral contraceptives[4]. The combination is particularly beneficial because it reduces irregular menstrual periods associated with spironolactone use and prevents pregnancy, which is important since spironolactone's anti-androgen properties can increase the risk of feminization in male fetuses during pregnancy[4]. Common side effects include nausea, breast tenderness, and menstrual irregularities[1][5][8]. More serious but less common side effects include high potassium levels, liver problems, and allergic reactions[6][10]. The combination is typically administered with spironolactone at doses ranging from 25-200 mg daily, often taken at night, along with an oral contraceptive pill taken according to its standard regimen[5][7]. Treatment duration is typically long-term, with improvements often taking six months or more to become apparent[7].
