Pfizer Inc announced on Monday that it was recalling several lots of the blood pressure medicine Accuretic as well as two authorized cheaper versions of the drug due to elevated levels of nitrosamine, a possible cancer-causing impurity.
To date, no reports of adverse events linked to the drug have been received, according to Pfizer.
Nitrosamines can be found in a variety of foods, including cured and grilled meats, dairy products, and vegetables. Long-term exposure to pollutants at levels that are higher than what is deemed safe may increase the risk of cancer.
Pfizer, on the other side, believes that consumers who use the drug are not at risk right now.
According to the business, patients who are currently taking the drugs should chat with their doctors about different treatment options.
Pfizer Canada issued a recall for Accuretic earlier this month owing to the presence of the same contaminant.
Chantix, an anti-smoking medicine, was also recalled last year due to high levels of nitrosamine in the pills.
