Ibigest SR 200 Tablet contains Progesterone (Natural Micronized) 200 mg, a vital hormone used in various gynecological and obstetric conditions. Progesterone is essential for regulating the menstrual cycle, supporting early pregnancy, and maintaining uterine lining stability. This sustained-release formulation ensures a controlled and prolonged release of progesterone, enhancing therapeutic efficacy and improving patient compliance. Ibigest SR 200 is commonly prescribed for the management of progesterone deficiency, treatment of menstrual disorders such as amenorrhea and abnormal uterine bleeding, and as part of hormone replacement therapy in menopausal women. Additionally, it is utilized in assisted reproductive technologies to support the luteal phase and prevent threatened miscarriage in early pregnancy. The natural micronized form of progesterone mimics endogenous hormone activity, offering better absorption and reduced side effects compared to synthetic progestins. Patients should use this medication under strict medical supervision, with dosage tailored to individual clinical needs. Common adverse effects may include dizziness, headache, breast tenderness, and mild gastrointestinal disturbances. Contraindications include known hypersensitivity to progesterone, unexplained vaginal bleeding, and certain hormone-sensitive cancers. Regular monitoring is advised to assess therapeutic response and detect any potential complications. Ibigest SR 200 Tablet is a reliable option for effective progesterone supplementation in various clinical scenarios.
