Yes and no: Amitiza (lubiprostone) is a novel type of "laxative". Technically speaking, it is a locally acting chloride channel activator in the gut. It should not affect the breath test (which measures for bacterial overgrowth). It's onset of action can range from a few minutes to a few hours dependent upon your motility.
