Femara, containing the active ingredient letrozole, stimulates ovulation by inhibiting aromatase, an enzyme that converts androgens to estrogens. This allows the pituitary gland to release more follicle-stimulating hormone (FSH), prompting the ovaries to produce more eggs.
Doctors prescribe Letrozole for women experiencing anovulation, a condition where the ovaries don’t release an egg. It’s commonly used as a first-line treatment for infertility in women with polycystic ovary syndrome (PCOS) as it improves ovulation rates in many.
Dosage and administration typically involve taking one 2.5mg or 5mg tablet daily for five days, starting on cycle day 3 or 5. The specific dosage and timing depend on individual patient needs and response. Close monitoring of follicle growth through ultrasound scans is vital to ensure appropriate response and avoid ovarian hyperstimulation syndrome (OHSS).
Side effects are generally mild and may include hot flashes, headaches, and joint pain. More severe side effects are rare but require immediate medical attention.
Letrozole’s success rate varies, influenced by factors like age, ovarian reserve, and underlying medical conditions. Studies show success rates ranging from 20% to 40% per cycle in women with PCOS.
Important Note: Letrozole is a prescription medication. Always consult your fertility specialist to discuss suitability, potential benefits, risks, and appropriate monitoring. They will help determine whether Letrozole is the right treatment for you.
