b12 injection versus oral Vitamin Injection: Benefits, Uses and Who Needs It B12 Injections or Oral B12:

Essential for the proper functioning of the digestive systems

L.LindstromR

Vitamin B12 shots are often prescribed for people with: Pernicious anemia (autoimmune destruction of intrinsic factor needed for B12 absorption) Gastrointestinal surgeries (e.g., gastric bypass, ileal resection) Crohns disease or celiac disease Chronic alcoholism Long-term use of acid-reducing medications Vegan diets without supplementation Infants or children with congenital absorption disorders (i.e., vitamin B12 for kids in clinical care) Injections ensure direct delivery into the bloodstream, bypassing the digestive system entirely

Like any insurance, your Medicare Part D plan will not cover all known medications and each Medicare drug plan can cover different drugs (or drug strengths) on the plan's formulary or drug list

Side effects may include feeling drowsy, dry mouth and constipation

Thank you very much for that clarification
