Fempro Tablet contains Letrozole 2.5mg, a non-steroidal aromatase inhibitor primarily used in the treatment of hormone receptor-positive breast cancer in postmenopausal women. Letrozole works by inhibiting the enzyme aromatase, which is responsible for converting androgens into estrogens, thereby reducing estrogen levels in the body. Lower estrogen levels help slow or reverse the growth of estrogen-dependent breast cancer cells. Fempro is often prescribed as adjuvant therapy following surgery or radiation, as well as for metastatic breast cancer. Additionally, Letrozole may be used off-label for ovulation induction in women with infertility due to polycystic ovary syndrome (PCOS). The typical dosage is one tablet taken orally once daily, but the exact regimen should be determined by a healthcare professional based on individual patient needs. Common side effects include hot flashes, joint pain, fatigue, and nausea, while serious adverse effects are rare but may include bone thinning or cardiovascular issues. Patients should inform their doctor of any pre-existing conditions or medications to avoid interactions. Fempro Tablet should be used under strict medical supervision, and regular monitoring is recommended to assess treatment efficacy and manage potential side effects.
