Aug 13 (Reuters) – Pfizer Inc (PFE.N) said on Friday it is recalling four additional lots of its anti-smoking treatment, Chantix, after finding elevated levels of cancer-causing agents called nitrosamines in the pills.
In June, the drugmaker said it was pausing distribution of certain lots of the anti-smoking drug out of an abundance of caution and pending further testing.
Including Friday’s recall, Pfizer has paused distribution of 16 lots of the drug. The lots were distributed to wholesalers in the United States and Puerto Rico from June 2019 to June 2021.
