Gestosurge 200 SR Tablet contains Progesterone (Natural Micronized) 200 mg, a vital hormone used primarily in hormone replacement therapy and the management of various gynecological conditions. Progesterone plays a crucial role in regulating the menstrual cycle, maintaining pregnancy, and supporting endometrial receptivity. This sustained-release formulation ensures a controlled and prolonged release of progesterone, enhancing therapeutic efficacy and patient compliance. Gestosurge 200 SR is indicated for the treatment of progesterone deficiency, luteal phase support in assisted reproductive technology (ART), prevention of threatened miscarriage, and management of menstrual disorders such as secondary amenorrhea and abnormal uterine bleeding. Additionally, it is employed in hormone replacement therapy for postmenopausal women to counterbalance estrogen-induced endometrial hyperplasia. The natural micronized form of progesterone mimics endogenous hormone activity, offering improved bioavailability and reduced side effects compared to synthetic progestins. Administration should be as prescribed by a healthcare professional, considering individual patient needs and clinical response. Common adverse effects may include mild headache, breast tenderness, and dizziness. Caution is advised in patients with hepatic impairment, thromboembolic disorders, or hypersensitivity to progesterone. Gestosurge 200 SR Tablet is a critical option in reproductive health management, ensuring effective hormonal balance and therapeutic outcomes.
