The song can be split into three sections, and in the album booklet, asterisk markings separate the lyrics to each of the sections. These sections are not named in the booklet, although during their BBC Radio 1 Rock Show performance, Gavin Harrison revealed that part two is called "The Pills I'm Taking". The song "What Happens Now?" from Nil Recurring EP uses a sample of the opener riff for this second movement.
The song's first section features a guitar solo by Alex Lifeson of Canadian progressive rock band Rush.
The full-length live projection for this song comes on the Fear of a Blank Planet DVD-A edition as a bonus feature.
"Anesthetize" was voted "Best track of 2007" by readers of the Dutch Progressive Rock Page.
