While studies show that discontinuing your use of the drug can return B12 levels back to normal in as little as 5 days, doing so is definitely not recommended as tuberculosis is a very serious, life-threatening condition
Therefore, this study aimed to compare two intranasal vitamin B12 dosage regimens (with and without loading dose) in elderly patients deficient in vitamin B12, focusing on vitamin B12 levels and three biomarkers indicative of deficiency: holotranscobalamin, methylmalonic acid, and total homocysteine
Additionally, patients taking medications with significant drug interactions or those with conditions that could be exacerbated by changes in gastric emptying or metabolic function should be carefully evaluated by their prescribing provider
