Bad Medicine

The harmony in 'Bad Medicine' runs on three chords throughout — E, A, and B — recycled across every section without substitution or modulation. That kind of harmonic austerity is a deliberate choice for arena rock: the scaffold needs to be simple enough that 20,000 people can feel it without thinking. What keeps the song from being monotonous is Fairbairn's production, which stacks guitar layers and gang vocals to create the illusion of momentum where the chords provide none. Sambora's tone and the rhythmic precision of the riff do more work here than any chord change could.

Jon Bon Jovi, Richie Sambora, and Desmond Child wrote 'Bad Medicine' during preparations for New Jersey, the band's follow-up to the multi-platinum Slippery When Wet. Child had already co-written two of Bon Jovi's biggest hits, and the trio returned to the same loud, hook-first formula. The lyric frames romantic obsession as medical dependency — a simple, repeatable conceit that gave the song an identity audiences could shout back from the upper deck.

Released in September 1988 as the lead single from New Jersey, 'Bad Medicine' reached the top of both the Billboard Hot 100 and the Cash Box chart, confirming Bon Jovi as the biggest rock act of the era. Written with Desmond Child and produced by Bruce Fairbairn, it packages an inescapable hook inside a three-chord riff workout that landed in heavy rotation from the first week. The video, featuring comedian Sam Kinison staging a mock takeover of the shoot, became one of MTV's most replayed clips of the year.
