Vitamin B12 has a good safety profile, but some important considerations include rare hypersensitivity reactions (including anaphylaxis) with injections, potential hypokalaemia during early treatment of severe deficiency, and possible cutaneous reactions
Risk factors that should prompt consideration of B12 deficiency include advancing age (reduced stomach acid production), strict vegan or vegetarian diets, pernicious anaemia, gastrointestinal surgery (particularly gastric bypass or ileal resection), long-term use of certain medications (metformin, proton pump inhibitors, H2-receptor antagonists), nitrous oxide exposure (including recreational use), and conditions affecting the gut such as Crohn's disease or coeliac disease
