title: Fixed drug eruption to oxybutynin.
abstract: Solitary fixed drug eruptions involving the lips and mouth are known to occur but are rarely seen in oral medicine clinical practice. Various drugs have been implicated as causative agents. We present a case of a fixed drug eruption on the lip caused by oxybutynin, a relationship not previously described.
