Letzol 5 Tablet contains Letrozole 5 mg, 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 the peripheral conversion of androgens to estrogens, thereby reducing estrogen levels in the body. This reduction in estrogen helps to slow or stop the growth of estrogen-dependent breast cancer cells. Letzol 5 is commonly prescribed as adjuvant therapy following surgery or radiation, as well as for metastatic breast cancer management. It may also be used off-label for ovulation induction in certain cases of infertility. The recommended dosage and duration of treatment should be determined by a healthcare professional based on the patient’s clinical condition. Common side effects include hot flashes, joint pain, fatigue, and nausea, although most patients tolerate the medication well. Caution is advised in patients with hepatic impairment or osteoporosis, and regular monitoring of bone density may be necessary during prolonged therapy. Letzol 5 should be used under strict medical supervision, and patients are advised to report any unusual symptoms promptly to their healthcare provider.
