LPS 100 Injection contains Progesterone 100 mg per dose and is indicated for use in various clinical conditions requiring progesterone supplementation. Progesterone is a naturally occurring steroid hormone essential for regulating the menstrual cycle, maintaining pregnancy, and supporting luteal phase function. This injectable formulation is primarily utilized in assisted reproductive technologies, such as in vitro fertilization (IVF), to support the luteal phase and improve implantation rates. Additionally, it may be prescribed for the management of progesterone deficiency, prevention of preterm birth in at-risk pregnancies, and treatment of amenorrhea or abnormal uterine bleeding related to hormonal imbalance. Administered intramuscularly, LPS 100 Injection ensures rapid absorption and bioavailability, providing effective hormonal support. The dosage and duration of therapy should be individualized based on the patient’s clinical condition and response, under strict medical supervision. Common adverse effects may include injection site pain, local irritation, and systemic reactions such as dizziness or fatigue. Contraindications include known hypersensitivity to progesterone or its components, undiagnosed vaginal bleeding, and certain hormone-sensitive malignancies. Careful assessment of patient history and monitoring during therapy is advised to optimize therapeutic outcomes and minimize risks.
