Hald SR 300 Tablet contains Progesterone (Natural Micronized) 300mg, a vital hormone used primarily in hormone replacement therapy and the management of various gynecological conditions. Progesterone is essential for regulating the menstrual cycle, supporting early pregnancy, and maintaining uterine lining health. This formulation utilizes natural micronized progesterone, which enhances bioavailability and mimics endogenous hormone activity more closely than synthetic analogs. Hald SR 300 is indicated for the treatment of progesterone deficiency, luteal phase support in assisted reproductive technology (ART), prevention of endometrial hyperplasia in postmenopausal women receiving estrogen therapy, and management of secondary amenorrhea. It may also be prescribed for threatened miscarriage and other progesterone-responsive conditions as determined by a healthcare professional. The sustained-release formulation ensures a gradual and consistent release of progesterone, optimizing therapeutic outcomes and minimizing side effects. Common adverse effects may include dizziness, headache, breast tenderness, and mild gastrointestinal disturbances. Contraindications include known hypersensitivity to progesterone, active thromboembolic disorders, and certain hormone-sensitive cancers. Use of Hald SR 300 should be under strict medical supervision with appropriate monitoring to tailor dosage and duration based on individual patient needs and response.
