[95] Intramuscular or intravenous injection [edit] Injection of hydroxycobalamin is often used if digestive absorption is impaired, [2] but this course of action may not be necessary with high-dose oral supplements (such as 0.51.0 mg or more), [97] [98] because with large quantities of the vitamin taken orally, even the 1% to 5% of free crystalline B 12 that is absorbed along the entire intestine by passive diffusion may be sufficient to provide a necessary amount
B12 injections are typically administered either intramuscularly (IM) or subcutaneously, with common sites being the deltoid, thigh, or gluteal muscles
These can include nausea, headache, and dizziness
