It might be on file with UNIT? I honestly can't remember, but there was this thing, back at the beginning of my third incarnation. I spent a some time in hospital, and I think the Brigadier made certain they didn't do anything that might hurt instead of help since he knew I wasn't human. Then again, that could have just been the doctors exercising common sense, but I wouldn't be surprised at all if the whole affair made it into a file. Not that I'd really know. I was a bit more concerned with finding my shoes.
That, and I distinctly remember telling Jo that some human medicines might kill me.
