Public Citizen joins four other organizations in petitioning the Food and Drug Administration (FDA) to require a more informative and comprehensive Black Box Warning for the smoking cessation drug varenicline (Chantix). The petition also asks that the FDA add restrictions to the Indications section of the product label warning against the drug’s use by individuals in sensitive or hazardous occupations, such as pilots, emergency medical workers, and others, in whom the neurological and psychiatric adverse effects of varenicline could pose a danger to themselves or others.
