But... it was actually in both categories. She had received it recently enough that is warranted being listed as a medication she was on, and she had an adverse reaction to it, which is why she said she was allergic to it. Both of those things are true (well... you can get picky about the fact that a dystonic reaction isn't technically an 'allergic' reaction...)

Generally speaking, dystonic reactions don't occur the first time you take a med. They commonly occur after dosing increases, etc, so it's quite likely she's been on haldol in some form or another for quite some time.
