Gest Dizire SR 200 Tablet contains Progesterone (Natural Micronized) 200 mg, a vital hormone used primarily in hormone replacement therapy and various gynecological conditions. Progesterone is essential in regulating the menstrual cycle, supporting early pregnancy, and maintaining the uterine lining. This sustained-release formulation ensures a consistent and prolonged therapeutic effect, enhancing patient compliance and efficacy. Gest Dizire SR 200 is indicated for the treatment of progesterone deficiency, luteal phase support in assisted reproductive technology (ART), management of amenorrhea, and prevention of threatened miscarriage in early pregnancy. It is also utilized in hormone replacement therapy for menopausal symptoms and endometrial hyperplasia prevention. The natural micronized form of progesterone closely mimics endogenous hormone activity, minimizing adverse effects compared to synthetic progestins. Administration should follow physician guidance, with dosage tailored to individual clinical needs. Common side effects may include mild gastrointestinal disturbances, headache, dizziness, and breast tenderness. Contraindications include known hypersensitivity to progesterone, unexplained vaginal bleeding, active thromboembolic disorders, and hormone-dependent malignancies. Regular monitoring is advised during prolonged therapy to assess therapeutic response and detect potential adverse effects. Gest Dizire SR 200 Tablet should be stored in a cool, dry place, away from direct sunlight and out of reach of children.
