Doses as high as 2 mg (2,000 g) daily by mouth or 1 mg monthly by intramuscular (IM) injection have been used to treat pernicious anemia without significant side effects (136)
Intramuscular (IM) injections are typically administered into the arm's deltoid muscle, the vastus lateralis muscle of the thigh, or the ventrolateral muscle of the hip
This usually occurs in individuals with underlying digestive conditions, those who have trouble absorbing all nutrients through digestion, or those with pernicious anemia, which specifically prevents B12 absorption
