Wonzest 200 SR Tablet contains Progesterone (Natural Micronized) 200 mg, a hormone essential for regulating the menstrual cycle and maintaining pregnancy. This sustained-release formulation ensures a controlled and prolonged release of progesterone, enhancing therapeutic efficacy and patient compliance. Progesterone plays a critical role in preparing the endometrium for implantation, supporting early pregnancy, and preventing uterine contractions. Wonzest 200 SR is indicated for the treatment of progesterone deficiency, luteal phase support in assisted reproductive technology (ART), management of amenorrhea, and prevention of threatened miscarriage. It may also be used in hormone replacement therapy (HRT) to counterbalance estrogen effects in postmenopausal women, reducing the risk of endometrial hyperplasia. The natural micronized form improves bioavailability and mimics endogenous progesterone activity. Patients should use this medication under medical supervision, with dosage tailored to individual needs. Common side effects may include dizziness, headache, breast tenderness, and mild gastrointestinal discomfort. Contraindications include known hypersensitivity to progesterone, unexplained vaginal bleeding, active thrombophlebitis, or hormone-dependent malignancies. Wonzest 200 SR should be stored in a cool, dry place away from direct sunlight. Regular monitoring by healthcare professionals is advised to ensure optimal therapeutic outcomes and minimize adverse effects.
