Ipreg 300 SR Tablet contains Progesterone (Natural Micronized) 300 mg, a vital hormone used in various gynecological and obstetric conditions. Progesterone is essential for regulating the menstrual cycle, supporting early pregnancy, and maintaining the uterine lining. Ipreg 300 SR is formulated as a sustained-release tablet to ensure a consistent and prolonged therapeutic effect, enhancing patient compliance and efficacy. It is primarily indicated for the treatment of progesterone deficiency states such as luteal phase support in assisted reproductive technology (ART), prevention of preterm birth in at-risk pregnancies, and management of amenorrhea or abnormal uterine bleeding due to hormonal imbalance. Additionally, it may be used in hormone replacement therapy (HRT) to counteract the proliferative effects of estrogen on the endometrium in postmenopausal women. The natural micronized form of progesterone improves bioavailability and mimics endogenous hormone activity more closely than synthetic analogs. Ipreg 300 SR should be used under medical supervision, with dosage tailored to individual patient needs. Common side effects may include mild dizziness, headache, or local reactions. Contraindications include known hypersensitivity to progesterone, unexplained vaginal bleeding, and certain thromboembolic disorders. Careful monitoring is advised during therapy to ensure optimal outcomes.
