In a statement Pfizer Inc said, it is recalling some batches of blood pressure drug Accuretic and two authorized cheaper versions of the drug citing the presence of elevated levels of a nitrosamine, a potential carcinogenic.
Pfizer said it has not received any reports of adverse events related to the drug till date.
“Nitrosamines are common in water and foods, including cured and grilled meats, dairy products and vegetables. Exposure to the impurities above acceptable levels over long periods of time could increase the risk of cancer. However, there is no immediate risk to patients taking the drug,” said Pfizer.
Earlier this month, Pfizer Canada recalled Accuretic citing the presence of the same impurity.
In 2021, Pfizer had also recalled its anti-smoking treatment, Chantix, citing high levels of nitrosamine in the pills.
