Pfizer recalls three blood pressure pills - including Accuretic and two generic brands

Pfizer recalls three blood pressure pills - including Accuretic and two generic brands - after finding it contains elevated levels of nitrosamines - a cancer causing impurity also found in cured meats

• Pfizer has recalled the blood pressure drug Accuretic, among others, after discovering nitrosamine impurities
• High levels of nitrosamine have been linked to multiple types of cancer after being exposed to high levels after long periods of time
• Nitrosamine can be common in some process foods, along with goods like cigarettes and makeup, and low levels are safe for humans
• The compound is often formed unintentionally as a result of a reaction between chemicals used in manufacturing and processing of goods 
• Last year Pfizer recalled all batches of its Champix anti-smoking treatment due to the presence of carcinogens that could cause cancer.
