Hubigest 200 SR Tablet contains Progesterone (Natural Micronized) 200 mg as its active ingredient, formulated to provide sustained release for optimal therapeutic effect. Progesterone is a naturally occurring hormone essential for regulating the menstrual cycle and maintaining pregnancy. Hubigest 200 SR is indicated for the treatment of various gynecological conditions such as luteal phase support in assisted reproductive technology (ART), prevention of endometrial hyperplasia in postmenopausal women receiving estrogen therapy, and management of secondary amenorrhea. The sustained-release formulation ensures a steady plasma concentration of progesterone, minimizing fluctuations and enhancing patient compliance. Upon administration, micronized progesterone is absorbed efficiently, mimicking endogenous hormone activity. This medication should be used under medical supervision, with dosage tailored according to the specific clinical indication and patient response. 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.
