Methylcobalamin vs. Cyanocobalamin — Which Injection Will You Get?
Most Indian doctors now prefer Methylcobalamin (the active, bioavailable form) over Cyanocobalamin (which must be converted by the liver). Methylcobalamin is preferred for patients with kidney issues or those who are heavy smokers. Your doctor's prescription will specify the form and dose — typically 1000 mcg IM injection, once weekly for 4–8 weeks, then monthly maintenance. immidit nurses administer whichever form your prescription specifies, brought in a cold-chain bag from an authorised pharmacy partner.
Who Needs B12 Injections Instead of Tablets?
Oral B12 is adequate for mild deficiency in healthy adults. Injections are recommended when: B12 levels are below 150 pg/mL; there is pernicious anaemia (inability to absorb B12 through the gut due to lack of intrinsic factor); the patient has had gastric bypass surgery; there is severe neurological involvement (subacute combined degeneration of spinal cord); or the patient is vegetarian/vegan with severe deficiency. In these cases, bypassing the gut with an IM injection ensures direct absorption.
How Often Will You Need the Injections?
A typical loading phase involves daily injections for 7 days, followed by weekly injections for 4 weeks, then monthly maintenance — though your doctor may adjust this based on your lab values and symptoms. immidit lets you schedule recurring visits at your preferred frequency, so your nurse arrives on the same day each week without you having to rebook each time.
