Pfizer said on Friday 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 Thursday; 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.
Nitrosamines are common in water and foods but exposure above acceptable levels; over long periods of time could increase the risk of cancer.
Pfizer last month also recalled some batches of another blood pressure drug Accuretic and two authorized cheaper versions; due to the presence of the possible carcinogen.
