Loading The Syringe Begin by gathering all the necessary supplies: the B12 solution, a syringe, a needle, alcohol swabs, and a sharps container
If dietary sources are insufficient, however, a doctor may recommend supplementation through pills or injections, depending on the cause of the deficiency.
Another B12 shot side effect is diarrhea, though its usually pretty mild

These include serious infection, uremia or renal failure, drugs with bone marrow suppression properties (e.g., chloramphenicol), or concurrent undiagnosed folic acid or iron deficiency anemia
