Nubal 15 Injection contains Methylcobalamin 1500 mcg, a biologically active form of vitamin B12 essential for hematopoiesis, neurological function, and DNA synthesis. It is indicated for the treatment and prevention of vitamin B12 deficiency, which may result from conditions such as pernicious anemia, malabsorption syndromes, chronic alcoholism, and certain neurological disorders. Methylcobalamin plays a critical role in the maintenance of myelin sheath integrity and supports nerve regeneration, making it beneficial in peripheral neuropathies, diabetic neuropathy, and other neurodegenerative diseases. Nubal 15 Injection is administered intramuscularly or intravenously, allowing for rapid absorption and bioavailability, especially in patients with impaired gastrointestinal absorption. The dosage and duration of therapy depend on the severity of deficiency and clinical response. Adverse effects are rare but may include mild injection site reactions, headache, or dizziness. Caution is advised in patients with hypersensitivity to cobalamin or any component of the formulation. Regular monitoring of hematological parameters and neurological status is recommended during prolonged therapy. Nubal 15 Injection should be used under medical supervision to ensure appropriate diagnosis, dosing, and to monitor for therapeutic efficacy and safety.
