Vitamin B12 - Hi, I got first B12 shot today and was NOT informed of the side effects that could?

What in the world are you talking about? I do no follow. What do these numbers represent, and lollipops? Please explain further what problems you are having?
I took B12 injections for years from the doctor's office, then she prescribed the cyanocobalamin vial and syringes for me to give to myself at home. I don't recall having a single side effect.
What have you read and what negative reactions have you experienced? It helped me and gave me more energy when I was suffering from extreme fatigue because of a B12 deficiency that showed up in my blood work.

I've been on B12 injections for several years now. Don't think I've had any side effects. What side effects have you had?

Hi! I actually just found out about a new and apparently the only oral prescription that can now be used to treat B12 deficiency. For you and all those struggling with B12 deficiency, this new alternative to the injections is called Eligen B12, not sure if you heard about it yet. Apparently it is the first and only true alternative to the intramuscular injection. I recently read that it works as well as the IM injection even if you don't have intrinsic factor (so even if you don't have normal gut absorption). It’s a once daily pill that apparently it came out a month or two ago. You might want to check it out. I'm pretty sure they have a website or your doctor may know about it

What side effects would you expect? Do you have nasty reactions to meat? To lollipops? I'm confused as to your concerns.

PS. 'I am on on BCP..' I couldn't even google.

You never said exactly what was going on. I must say that in all my years as a nurse I've 'never had a lt react to it.
