Conditions associated with elevated B12 levels include: Liver disease : Hepatocellular damage releases stored B12 into circulation, with levels correlating with disease severity in conditions such as cirrhosis, hepatitis, and hepatocellular carcinoma Renal impairment : Reduced kidney function decreases B12 clearance, leading to accumulation Haematological malignancies : Myeloproliferative disorders, acute leukaemia, and polycythaemia vera can elevate B12 through increased production of B12-binding proteins (transcobalamins) Solid tumours : Certain cancers, particularly those affecting the liver or gastrointestinal tract, may elevate B12 levels A specific concern relates to cyanocobalamin in patients with Leber's hereditary optic neuropathy , a rare mitochondrial disorder

For patients requiring ongoing suppression of gastric acid production including those with frequent relapse of symptomatic GERD or erosive esophagitis G-Omeprazole 40 mg/vial is indicated for long-term maintenance therapy at the lowest effective dose
Those with deficiencies may need up to 1,000 mcg daily until levels normalise, then maintenance doses of 25-100 mcg
Then, youll need regular doses to keep B12 levels right
