(WWTI) — Pfizer is voluntarily recalling five batches of its hypertension medication Accupril because the pills contain elevated levels of a cancer-causing chemical, according to the Food and Drug Administration (FDA).

The recall was issued due to the presence of a nitrosamine, known as Nnitroso-quinapril. Recent testing found that the amount of nitrosamines within the Accupril tablets was above the level set for an acceptable daily intake, according to the FDA.

“Nitrosamines are common in water and foods, including cured and grilled meats, dairy products, and vegetables,” the FDA explained. “Everyone is exposed to some level of nitrosamines. These impurities may increase the risk of cancer if people are exposed to them above acceptable levels over long periods of time.”

Accupril is used to treat hypertension, meaning it is intended to lower blood pressure. It can also be used to manage heart failure as adjunctive therapy when added to conventional therapy like diuretics or digitalis.

“Although long-term ingestion of Nnitroso-quinapril may be associated with potential increased cancer risk in humans, there is no immediate risk to patients taking the medication,” the recall states.

Anyone who regularly takes the medication is encouraged to consult their doctor or health provider about alternative treatment options.

The recalled product lots were distributed nationwide distributors in the United States and Puerto Rico from December 2019 to April 2022.
