This is horrifying.

I've ended up with an erroneous medicine allergy on my record because I mentioned a well-known side effect to that medicine during an office visit a couple years ago. Some "moving part" in the system (be it a human entering the doctor's notes, a transcriptionist, etc) interpreted what I said as an allergic reaction and now I get asked about that "allergy".

I've asked to have it fixed but other facilities have gotten "copies of my records" and I've had it crop up in visits to other providers.

Thankfully it's not a medicine that's likely to ever be administered to me (or not administered when I'm incapacitated and can't point out the error) so I'm not worried, practically. On principle, though, it really frustrates me. It seems like it will never be fixed.
