Just 200 SR Tablet contains Progesterone (Natural Micronized) 200 mg, a vital hormone used primarily in hormone replacement therapy, menstrual disorders, and assisted reproductive technology protocols. Progesterone is essential for regulating the menstrual cycle and maintaining pregnancy by preparing the endometrium for implantation and supporting early gestation. The natural micronized formulation enhances bioavailability and absorption, ensuring effective plasma concentration levels. Just 200 SR Tablet is indicated for the treatment of progesterone deficiency, luteal phase support in assisted reproductive techniques such as in vitro fertilization (IVF), management of secondary amenorrhea, and prevention of endometrial hyperplasia in postmenopausal women receiving estrogen therapy. It may also be used in the management of abnormal uterine bleeding and as part of hormone replacement therapy in menopausal women. The sustained-release formulation allows for prolonged progesterone release, minimizing dosing frequency and improving patient compliance. Administration should be guided by a healthcare professional, with dosage tailored to individual clinical conditions. Common side effects may include dizziness, headache, breast tenderness, and mild gastrointestinal disturbances. Contraindications include known hypersensitivity to progesterone, unexplained vaginal bleeding, and certain hormone-dependent malignancies. Monitoring and periodic evaluation are recommended during therapy to ensure safety and efficacy.
