Sept 16 (Reuters) – Pfizer Inc (PFE.N) said on Thursday it was recalling all lots of its anti-smoking treatment, Chantix, due to high levels of cancer-causing agents called nitrosamines in the pills.
The drugmaker paused distribution of the drug in June, and has already recalled a number of lots of the medicine so far.
Pfizer asked wholesalers and distributors on Thursday to stop the use and distribution of the tablets immediately.
