Administering the Injection Choose the Injection Site : IM Injection Sites : Common sites include the deltoid muscle (upper arm), gluteus maximus (buttocks), and vastus lateralis (thigh)
## **Documentation requirements** Documentation should include: - The diagnosis or condition showing low serum vitamin B12, pernicious anemia, or other diseases classified by B-group deficiencies
Side effects from B12 supplementation are uncommon but may include: Mild gastrointestinal symptoms such as nausea or diarrhoea, typically with very high oral doses Headache or dizziness in some individuals Skin reactions (rash, itching) at injection sites when using intramuscular preparations Rare but serious allergic reactions, including anaphylaxis with injectable forms Hypokalaemia (low potassium) may occur during rapid correction of severe megaloblastic anaemia If you experience symptoms of a severe allergic reaction (difficulty breathing, severe rash, swelling of face or throat) after taking B12, seek immediate medical attention
If you are sensitive, or you experience fatigue as opposed to an increase in energy when taking vitamin B12 then using a smaller dose less frequently will likely be better for your body
The two are closely related (same region of growth hormone, slightly different structure)
