Anyone had an allergic reaction to sublingual B12?

I purchased my sublingual B12 today, and used it right away in my car. Within several minutes, my face felt (and looked) like a funace. My throat started closing up - I was having difficulty breathing. All this while driving! I pulled over to catch my breath. I have a twenty minute ride to work. When I got there, my co-workers asked me if I had been out in the sun, I looked so sunburned! I have taken B12 this way for months, but I had the same reaction about a month ago. I thought at the time that it was to something else. I need my B12...but now I'm afraid to take it. Any suggestions?
