Pfizer said on April 22 that it was voluntarily recalling five batches of its Accupril blood pressure tablets after finding elevated levels of a potential cancer-causing agent in the medicine.
The drugmaker said it was not aware of any reports of adverse events related to the recalled batches, which were distributed in the United States and Puerto Rico from December 2019 to April 2022.
Pfizer Canada also recalled all lots of three doses of Accupril on April 21 after finding the same impurity to be above acceptable levels.
Pfizer said there was no immediate risk to patients taking this medication, in which the agent, a nitrosamine, was found.
