The two single most lethal drugs were the anti-smoking drug varenicline -- marketed as Chantix -- and the blood thinner heparin. While heparin was responsible for killing a 102 people and injuring 779, the vast majority of these cases were associated with a batch of contaminated medication imported from China. Since the discovery of the tainted drugs, injuries and deaths from heparin have dropped off.
