Treatment Options for Polycystic Ovary Syndrome (PCOS)
The first-line treatment for PCOS includes lifestyle modifications combined with specific medications tailored to symptoms, with clomiphene citrate being the primary medication for women seeking pregnancy. 1
Lifestyle Modifications - First-Line Treatment
Lifestyle changes form the cornerstone of PCOS management:
- Weight reduction: Even a modest 5-10% weight loss can significantly improve ovulation, pregnancy rates, and hormonal profiles 1, 2
- Dietary recommendations:
- Energy deficit of 30% or 500-750 kcal/day (1,200-1,500 kcal/day)
- Focus on low glycemic index foods and anti-inflammatory diet patterns
- Limit calories from fat to 25-30% and saturated fat to <7%
- Avoid trans fats
- Ensure adequate magnesium and zinc intake 1
- Physical activity:
Medication Options Based on Treatment Goals
For Women Seeking Pregnancy:
Ovulation Induction:
- Clomiphene citrate: First-line medication with approximately 80% of PCOS patients ovulating and 50% conceiving 1, 3
- Important precautions: Must exclude pregnancy, ovarian cysts, abnormal vaginal bleeding, and liver dysfunction before starting treatment 3
- Monitoring: Regular evaluation of menstrual cycles and ovulation using basal body temperature charts 1, 3
- Risk awareness: Monitor for ovarian hyperstimulation syndrome (OHSS), which can progress rapidly and become serious 3
Additional options:
For Menstrual Irregularities and Hyperandrogenism:
Combined oral contraceptives (COCs):
Anti-androgens:
- Spironolactone: For hirsutism and acne resistant to first-line treatments
- Topical treatments: Eflornithine cream for facial hirsutism 1
Metformin:
- Starting dose of 500 mg/day with gradual increase as tolerated
- Improves insulin sensitivity and reduces hyperandrogenism 1
Monitoring and Follow-up
- Regular evaluation of menstrual cycles every 3-6 months
- Annual assessment of metabolic parameters
- Screening for cardiovascular risk factors, including dyslipidemia
- Assessment of BMI and waist-hip ratio to evaluate central obesity
- Screening for anxiety and depression 1
Important Cautions and Considerations
- Endometrial protection: Chronic anovulation increases risk of endometrial hyperplasia and carcinoma, requiring appropriate treatment 4
- OHSS risk: Patients with PCOS may be unusually sensitive to ovulation induction medications; start with lowest doses 3
- Visual symptoms: Discontinue clomiphene citrate immediately if visual disturbances occur 3
- Long-term health: PCOS patients should be monitored for metabolic complications including diabetes, dyslipidemia, hypertension, and non-alcoholic fatty liver disease 5
- Sleep apnea: Screen for this condition as it occurs more commonly in women with PCOS 5
Treatment Algorithm
- Start with lifestyle modifications for all patients
- Add medication based on primary goal:
- For pregnancy: Clomiphene citrate ± metformin
- For menstrual regulation/hyperandrogenism: COCs or metformin
- Monitor response and adjust treatment accordingly
- Progress to second-line options if initial treatment fails
Remember that PCOS is a spectrum of disorders requiring a comprehensive approach addressing reproductive, metabolic, and psychological aspects of the condition.
