There are biochemical reasons that suggest an intramuscular (IM) injection delivers hydroxocobalamin to the bloodstream more rapidly and potentially more effectively than the subcutaneous (SC) route
The other components are: sodium dihydrogen phosphate dihydrate, sodium chloride, water for injection purposes, sodium hydroxide for pH value setting
Still in the early stages my second order
The Financial Case for Injection Therapy For people with a confirmed deficiency, especially those with an absorption problem, injections can be a sensible choice compared to pills
