March 22, 2022 -- Drug giant Pfizer is voluntarily recalling some high blood pressure medications due to unacceptable levels of a potential carcinogen, the company announced.

The affected products are quinapril HCl/hydrochlorothiazide (Accuretic) tablets that Pfizer distributes, and two authorized generics, quinapril plus hydrochlorothiazide and quinapril HCl/hydrochlorothiazide, distributed by Greenstone. The recall is over higher than accepted levels of N-nitroso-quinapril, a compound known as a nitrosamine.

"Although long-term ingestion of N-nitroso-quinapril may be associated with a potential increased cancer risk in humans, there is no immediate risk to patients taking this medication," Pfizer said in a news release.

If you’re taking any of the recalled drugs, contact your doctor about alternatives.

There have been no reports of injuries or illness related to the recall, the company said.
