Gesterol 200mg Tablet SR contains natural micronized progesterone, a bioidentical hormone essential for regulating the menstrual cycle and maintaining pregnancy. Each sustained-release tablet delivers 200mg of progesterone, designed to provide a controlled and prolonged release, ensuring stable plasma levels over an extended period. This formulation is primarily indicated for the treatment of progesterone deficiency-related conditions, including luteal phase support in assisted reproductive technology, prevention of threatened or recurrent miscarriage, and management of secondary amenorrhea. Additionally, Gesterol may be employed in hormone replacement therapy to counterbalance estrogen effects in postmenopausal women, thereby reducing the risk of endometrial hyperplasia. The natural micronized form enhances absorption and bioavailability, closely mimicking endogenous progesterone. Administration should follow medical guidance, with dosage and duration tailored to individual clinical needs. Common side effects may include dizziness, headache, breast tenderness, and mild gastrointestinal disturbances. Contraindications include known hypersensitivity to progesterone, active thrombophlebitis, or hepatic impairment. Caution is advised in patients with a history of thromboembolic disorders or hormone-sensitive malignancies. Regular monitoring and follow-up are recommended to assess therapeutic response and detect any adverse effects. Gesterol 200mg Tablet SR is a valuable therapeutic agent in managing progesterone-related disorders under professional supervision.
