It is used to prevent or treat vitamin B12 deficiency and may be prescribed for certain types of anemia and nerve-related problems associated with B12 deficiency. Vitamin B12 is essential for healthy red blood cell formation, normal nerve function, and DNA synthesis. ## KEY BENEFITS * Helps correct or prevent vitamin B12 deficiency * Supports healthy red blood cell production * Supports normal nerve function * Contributes to normal DNA synthesis * May help manage neurological symptoms associated with vitamin B12 deficiency * Supports normal energy metabolism * Helps maintain healthy blood cells and nervous-system function ## USES / INDICATIONS Mecobalamin 500 mcg may be used for: * **Vitamin B12 deficiency** * Certain types of **megaloblastic anemia** caused by vitamin B12 deficiency * Peripheral neuropathy associated with vitamin B12 deficiency * Nerve-related symptoms caused by inadequate vitamin B12 * Vitamin B12 deficiency associated with inadequate dietary intake or impaired absorption The cause of vitamin B12 deficiency should be identified because some patients require long-term supplementation or treatment of an underlying absorption problem. ## HOW IT WORKS Mecobalamin is a biologically active form of **vitamin B12**. Vitamin B12 participates in important biochemical reactions involved in: * DNA synthesis * Red blood cell formation * Myelin production and maintenance * Normal nerve function * Amino acid and fatty-acid metabolism By restoring inadequate vitamin B12 levels, mecobalamin can help correct biochemical abnormalities and support normal blood and neurological function. ## DOSAGE & ADMINISTRATION The appropriate dose depends on the severity and cause of vitamin B12 deficiency and the formulation being used. * Take Mecobalamin 500 mcg exactly as directed by your healthcare professional. * It may generally be taken with or without food. * Swallow the tablet with water if using an oral formulation. * Follow the prescribed schedule consistently. * Do not take higher doses than recommended unless instructed by a healthcare professional. ### Missed dose Take the missed dose when remembered unless it is nearly time for the next scheduled dose. Do not take a double dose to compensate. > **Important:** Mecobalamin 500 mcg is available in different formulations, including oral and injectable products.

Seek medical attention for: * Severe rash * Swelling of the face, lips, tongue, or throat * Difficulty breathing * Severe dizziness or fainting ## PRECAUTIONS & WARNINGS ### Confirm the cause of anemia Vitamin B12 supplementation should not be used to self-treat unexplained anemia. Proper diagnosis is important because different types of anemia require different treatments. ### Vitamin B12 deficiency and nerve damage Prolonged vitamin B12 deficiency can cause neurological problems. Early diagnosis and appropriate treatment are important because some nerve damage may become irreversible if deficiency is left untreated. ### Allergy Do not use mecobalamin if you have previously experienced a serious allergic reaction to mecobalamin, vitamin B12, cobalt, or any component of the product. ### Kidney or liver conditions Inform your healthcare professional if you have significant kidney or liver disease so that your overall treatment can be appropriately assessed. ### Pregnancy and breastfeeding Vitamin B12 is important during pregnancy and breastfeeding. Mecobalamin should be used according to professional advice, particularly when supplementation is being used to treat a confirmed deficiency. ## DRUG INTERACTIONS Mecobalamin generally has a low potential for clinically significant drug interactions, but certain medicines can affect vitamin B12 status or absorption. Important examples include: * **Metformin** — long-term use may reduce vitamin B12 levels. * **Proton pump inhibitors (PPIs)** such as omeprazole and pantoprazole — prolonged use may reduce vitamin B12 absorption. * **H2-receptor blockers** such as famotidine — long-term use may reduce vitamin B12 absorption. * **Chloramphenicol** — may interfere with the blood-cell response to vitamin B12 therapy in some situations. * Other medicines that affect gastrointestinal absorption may alter vitamin B12 status. Tell your doctor or pharmacist about all prescription medicines, OTC medicines, vitamins, and herbal supplements you take. ## STORAGE INFORMATION * Store Mecobalamin 500 mcg according to the manufacturer's instructions. * Keep at room temperature unless the product label specifies otherwise. * Protect from excessive heat, moisture, and direct sunlight. * Keep the medicine in its original packaging. * Keep out of reach and sight of children. * Do not use after the expiry date. * Do not use the product if the packaging is damaged or the medicine appears abnormal. ## PRESCRIPTION STATUS **Mecobalamin 500 mcg may be available as a prescription or non-prescription medicine depending on the formulation and local regulations.** Prescription requirements vary by country and product.
