Hald 400 Soft Gelatin Capsule contains Progesterone (Natural Micronized) 400 mg, a key hormone involved in the regulation of the menstrual cycle and maintenance of pregnancy. This formulation is primarily indicated for hormone replacement therapy in women with progesterone deficiency, treatment of amenorrhea, abnormal uterine bleeding due to hormonal imbalance, and support of luteal phase in assisted reproductive technology (ART) protocols. Progesterone plays a critical role in preparing the endometrium for implantation and sustaining early pregnancy. The natural micronized form enhances bioavailability and absorption when administered orally. Hald 400 is typically prescribed under medical supervision, with dosage and duration tailored to individual patient needs and clinical indications. Common side effects may include mild dizziness, headache, breast tenderness, and gastrointestinal disturbances; however, serious adverse reactions are rare. Contraindications include known hypersensitivity to progesterone, unexplained vaginal bleeding, active thromboembolic disorders, and hormone-dependent malignancies. Caution is advised in patients with liver dysfunction or cardiovascular disease. Regular monitoring and follow-up are recommended to assess therapeutic response and detect any potential adverse effects. Hald 400 Soft Gelatin Capsule should be stored in a cool, dry place away from direct sunlight and out of reach of children.
