Vitamin B12 injections are generally safe, but some people may experience side effects, such as pain, redness, or swelling at the injection site, mild headaches, dizziness, nausea, or itching

Treatment typically involves hydroxocobalamin 1mg intramuscular injections three times weekly for two weeks (loading dose), followed by maintenance injections every two to three months
