I'm not real good with regex's myself, but maybe something like this
will work:

^\s*\[Alert: This Rx was initially created on
[\d]{1,2}/[\d]{1,2}/[\d]{4}\.\]\s*$

Adjust as you see fit.

BTW, I find The Regex Coach (google for it - I don't have URL handy) to
be helpful in designing appropriate regex's.
