"Bad Medicine" is a single by American rock band Bon Jovi. It was written by Jon Bon Jovi, Richie Sambora, and Desmond Child. It was released in September 1988 as the lead single from the band's album New Jersey.
The song is highlighted by a near constant keyboard playing by David Bryan that is well defined in the beginning of the song and at several interludes, as well as loud guitar playing by Richie Sambora, background singing in the bridge and chorus, and a loud fast-paced delivery of lyrics by Jon Bon Jovi. It is one of the more upbeat and hard rocking songs on New Jersey.
Towards the end of the song, Jon says he is running out of breath and has to go, but then relents, saying "I'm not done...one more time, with feelin'" and the band finishes the song with another repeat of the chorus.
There are two videos for the song, one with the band live in concert, and a more well-known live video in which a crowd of young people waiting in line to get into the video shoot is asked by Sam Kinison if they (the public) "can make a better Bon Jovi video than these guys can." The crowd gives a very enthusiastic response, and members of the crowd are given hand-held cameras and invited onstage to help shoot the video.
