Don't be!: I am not sure why you are receiving B12 injections but your levels will slowly drift down. I have never seen toxicity due to elevated B12 levels, even that high. For further info, check the Linus Pauling Institute at Oregon State University (micronutrient center)

No reason to worry: There is no known toxicity from Vitamin B12. Unlike other B vitamins, our bodies can store B12, so a high level is not unusual after having weekly shots and is nothing to worry about. See http://lpi.oregonstate.edu/mic/vitamins/vitamin-B12 If someone has high B12 who has not been supplementing with it then it might be a sign of serious health problems, but absolutely no concern in your case.
