Pharmaceutical giant, Pfizer, has recalled five batches of its Accupril blood pressure tablets after finding elevated levels of a potential cancer-causing agent in the medicine.
The drug was distributed in the United States and Puerto Rico from December 2019 to April 2022.
Pfizer said they believed there was no immediate risk to patients taking the medication, in which the agent, a nitrosamine, was found.
The company said it was not aware of any reports of adverse events related to the recalled batches, but that the batches were voluntarily recalled.
Nitrosamines are commonly found in water and foods but experts warn that exposure above acceptable levels over long periods of time could increase the risk of cancer.
Last month, Pfizer also recalled some batches of a different blood pressure drug Accuretic due to the presence of the possible cancer-causing agent.
