Pfizer pauses global sales of Chanitix (aka Champix [varenicline]) over possible carcinogen contamination

Pfizer has identified increased levels of nitrosamines, which are potentially cancer-causing agents. It indicated it was pausing distribution out of an abundance of caution & would continue investigations, currently highlighting benefits outweigh very low potential risks, if any.

SPS commentary:

A Supply Disruption Alert recently issued by the DHSC advises on alternative management options.
