Maintane 250 Injection contains Hydroxyprogesterone 250 mg, a synthetic progestogen used primarily for its potent progestational activity. It is indicated for the prevention of preterm birth in pregnant women with a history of spontaneous preterm delivery and for the management of amenorrhea or abnormal uterine bleeding due to hormonal imbalance. Hydroxyprogesterone acts by mimicking the natural hormone progesterone, thereby maintaining the uterine lining and supporting pregnancy. This injectable formulation is administered intramuscularly, allowing for sustained release and prolonged therapeutic effect. The dosage and duration of treatment should be determined by a healthcare professional based on the patient’s clinical condition and response. Maintane 250 Injection is contraindicated in patients with known hypersensitivity to hydroxyprogesterone or any component of the formulation, active thrombophlebitis, or history of thromboembolic disorders. Caution is advised in patients with hepatic impairment, cardiovascular disease, or diabetes. Common adverse effects may include injection site reactions, headache, nausea, and dizziness. Regular monitoring is recommended during therapy to ensure efficacy and detect any potential side effects. Maintane 250 Injection should be stored at controlled room temperature and protected from light. It is essential to use this medication under strict medical supervision.
