Traditional treatment of Vitamin B₁₂ deficiency has been the Cobalamin administration via periodic intramuscular injections following different rules depending from deficit severity and clinical picture present. Despite that from 50s and 60s of past century, it was established that oral B₁₂ therapy is as effective as injections ones in treatment of this type of deficiency, in practice it looks like a not very accepted fact. Researches aimed to assess this alternative, and why still its use has not been completely understood, suggest that the change to a Vitamin B₁₂ treatment implicates significant savings in terms of financial costs, time of physicians and health staff, and the drawbacks and annoyances for patients, whom in general, accept well the change of therapy.
