Last month, the Food and Drug Administration warned of newly discovered cardiovascular risks associated with Pfizer’s popular smoking-cessation drug Chantix. But it turns out those risks, which include higher occurrence of heart attack and other adverse cardiovascular events in Chantix users with heart disease, pale in comparison to the findings of a larger study that found many of the same risks exist in Chantix patients with no heart disease.

BBC investigates Chantix suicides in the UK

An investigative report aired by the British Broadcasting Company (BBC) tells the stories of two people who became suicidal after taking Chantix (marketed by Pfizer as Champix in Europe and the UK).

The McGhee’s daughter found Karen and ran to get her father’s help, shouting that her mother ... Read More
