Megalob (500mcg) 1ml, 10 Ampoule Injections

Methylcobalamin, the active form of vitamin B12, exerts its therapeutic effects primarily through its role as a coenzyme in various enzymatic reactions. It plays a crucial role in the methylation of homocysteine to methionine, which is essential for DNA synthesis, neurotransmitter production, and the maintenance of myelin sheaths in the nervous system. Methylcobalamin promotes the regeneration of damaged nerve cells and enhances nerve conduction, thereby improving neurological function. It also supports the production of red blood cells and maintains the integrity of the myelin sheath, which is vital for optimal nerve function. By participating in these metabolic processes, methylcobalamin helps alleviate neurological symptoms, enhance nerve regeneration, and improve overall nerve health.

Following are the precautions and warnings for Methylcobalamin injection:

• Methylcobalamin should be administered with caution in patients with hypersensitivity to any of its components, and an alternative form of vitamin B12 should be considered in such cases.
• It is crucial to monitor patients with Leber's disease (a hereditary optic nerve atrophy) as the drug can cause severe optic atrophy.
• Patients with anemia should undergo a complete blood examination before starting treatment to rule out other causes of anemia.
• Those with renal impairment may require dosage adjustments, and it is advisable to consult a healthcare professional for guidance.
• The injection should be used with caution in individuals with chronic alcohol consumption or liver disease, as these conditions can affect vitamin B12 metabolism.
• Methylcobalamin should be used with caution in patients with a history of blood clots or thrombosis, as it may increase the risk of blood clotting.
• This medication may cause allergic reactions, including skin rashes, itching, and swelling. Discontinue use and seek medical attention if these symptoms occur.

Following are the drug interactions for Methylcobalamin injection:

• Alcohol intake may interfere with the absorption of Methylcobalamin, reducing its effectiveness.
• Methylcobalamin may decrease the effectiveness of certain antibiotics like tetracyclines and macrolides, leading to reduced antibiotic efficacy.
• Concomitant use with chloramphenicol may decrease the response to Methylcobalamin in treating conditions like pernicious anemia.
• The effects of colchicine may be decreased when used with Methylcobalamin, requiring close monitoring.
• Drugs affecting the central nervous system, such as opioids and benzodiazepines, may have enhanced effects when combined with Methylcobalamin.
• Methylcobalamin may interact with certain diabetes medications, potentially affecting blood sugar control.
• Caution is advised when using with anticonvulsants, as Methylcobalamin may alter seizure thresholds.

Following are the food interactions for Methylcobalamin injection:

• Methylcobalamin can interact with foods rich in nitrates, such as processed meats and certain vegetables, potentially affecting blood pressure.
• Avoid excessive consumption of alcohol as it may interfere with the absorption and effectiveness of Methylcobalamin, leading to reduced therapeutic benefits.
• Foods containing high levels of folic acid, like leafy green vegetables and fortified cereals, should be consumed in moderation to maintain a balanced vitamin B12 and folate ratio.
• Ensure a varied diet to obtain adequate amounts of vitamin B12 from natural sources like meat, fish, and dairy products, which can help optimize the benefits of Methylcobalamin injections.
• Some plant-based milks, like soy milk, may contain compounds that can interfere with vitamin B12 absorption, so consider alternative sources or consult a healthcare provider for guidance.
• Avoid excessive intake of raw eggs as they contain a protein called avidin, which can bind to Methylcobalamin and reduce its bioavailability.
• Certain types of tea, such as black tea, may contain tannins that can hinder the absorption of Methylcobalamin. Consider reducing tea consumption around the time of injection.
• Consult a healthcare professional for personalized advice, especially if you have specific dietary preferences or restrictions, to ensure optimal results from Methylcobalamin therapy.

Methylcobalamin injection should be stored in a cool, controlled environment, preferably between 20°C and 25°C (68°F and 77°F), in its original packaging to maintain sterility.
