Letrozole is an oral aromatase inhibitor used to treat hormone-receptor-positive breast cancer in postmenopausal women and to induce ovulation for fertility issues, such as PCOS. By blocking the aromatase enzyme, it reduces estrogen production by up to 99%. Common side effects include hot flashes, joint pain, fatigue, and headache.
