Letrozole (commonly sold as Femara) is an oral aromatase inhibitor used to treat hormone-receptor-positive breast cancer in postmenopausal women. It works by significantly lowering estrogen levels in the body, which slows or stops the growth of cancer cells. It is also prescribed off-label to stimulate ovulation in fertility treatments.Uses for LetrozoleBreast Cancer: Primarily used as adjuvant (after surgery or radiation) therapy, initial treatment for advanced breast cancer, or following a 5-year course of tamoxifen.Infertility: Used to induce ovulation in women with conditions like polycystic ovary syndrome (PCOS) or unexplained infertility.Common Side EffectsBecause it reduces estrogen, it frequently causes symptoms associated with low hormone levels:Joint and muscle painHot flashes and night sweatsFatigue and general weaknessNausea or digestive discomfortImportant PrecautionsPregnancy: Letrozole can harm an unborn baby. It must not be used during pregnancy, and effective contraception is required during and for at least three weeks after treatment.Bone Health: Long-term use can decrease bone mineral density, increasing the risk of osteoporosis or fractures.Interactions: Letrozole should not be taken alongside tamoxifen or other estrogen-containing therapies (like hormone replacement therapy), as this can interfere with its effectiveness.For more specific information regarding your treatment, consult your healthcare provider or pharmacist, and refer to detailed guides such as the Cleveland Clinic Letrozole Information or the Mayo Clinic Letrozole Guide.
