Femara (letrozole) is a medication commonly used to stimulate ovulation in women experiencing infertility. It works by blocking the production of estrogen, which in turn triggers the pituitary gland to release more follicle-stimulating hormone (FSH) and luteinizing hormone (LH). This increased hormone production promotes follicle growth and maturation, increasing the chances of egg release.
How Femara Works
Unlike other fertility drugs, Femara is an oral medication, making it convenient for many patients. Doctors typically prescribe it for 5 days, starting on cycle day 3, 5, or 2-5 depending on individual circumstances. Dosage is usually 2.5mg to 5mg daily, adjusted based on patient response and doctor’s assessment. Regular blood tests and ultrasounds monitor follicle development and ensure safe medication use.
Success Rates and Considerations
Success rates vary considerably, depending on factors like age, overall health, and the underlying cause of infertility. Studies indicate that the live birth rate per cycle with Femara ranges from 8% to 20%, although these numbers aren’t uniformly consistent across all studies. Furthermore, multiple pregnancies occur more frequently with Femara than with Clomid, representing both a benefit and a risk. Your doctor will discuss these possibilities and any potential complications with you.
Side Effects and Monitoring
Common side effects include hot flashes, headaches, and joint pain. Less frequent but possible side effects include ovarian hyperstimulation syndrome (OHSS), a condition requiring immediate medical attention. Regular monitoring throughout the treatment cycle is vital to detect any potential issues promptly and adjust treatment accordingly. Discuss any concerns with your healthcare provider.
