symptoms worse after b12 injections Vitamin Injection Side Effects and Safety Vitamin B12 Side Effects

The patients blood may have returned to normal but that might not mean that they would do as well on tablets as they did on injections

Increasing should be based on careful assessment of response, not impatience for faster results

Then theres other evidence such as where tablets have been introduced to treat patients with Pernicious Anaemia doctors still keep on prescribing the injections and anyway, patients are easily able to purchase injectable B12 from other sources and treat themselves

Pharmacokinetics: Cyanocobalamin is administered intranasally, orally, and parenterally, while hydroxocobalamin is administered only parenterally. Once absorbed, vitamin B12 is highly bound to transcobalamin II, a specific B-globulin carrier protein and is distributed and stored primarily in the liver as coenzyme B12. The bone marrow also stores a significant amount of the absorbed vitamin B12. This vitamin crosses the placenta and is distributed into breast milk. Enterohepatic recirculation conserves systemic stores. The half-life is about 6 days (400 days in the liver). Elimination is primarily through the bile; however, excess cyanocobalamin is excreted unchanged in the urine

Always confirm dosing with your provider and pharmacy label

I used to work for a PA and got my injections weekly for free, now that I have to pay I love that I can administer them on my own
