Pfizer's quit smoking drug Champix has black triangle warning removed in UK

23 May 2016

US pharma major Pfizer (NYSE: PFE) has announced that the black triangle safety warning for its smoking cessation drug Champix (varenicline) has been removed in the UK.

The drug, known as Chantix in the USA, has had its label updated in light of new data showing that it was not associated with an increased risk of serious neuropsychiatric adverse events, as had previously been claimed.

This data came from the largest ever randomized clinical trial of approved smoking cessation medicines, entitled EAGLES - Evaluating Adverse Events in a Global Smoking Cessation Study.
