Pernicious anemia: I do not know what caused the collapse/ cardiac arrest(faint or go to ER?) - which is serious so before taking another form would discuss with doctor and would take the first dose in the doctor's office where you can be monitored. High dose oral supplementation is effective as well, as is sublingual and foods with B12 (liver beef, eggs) f/u/w/ doc http://www.aafp.org/afp/2011/0615/p1425.html
