Pfizer Voluntarily Recalls Lots of ACCUPRIL® (Quinapril HCl) Because they Contain Nitroso-Quinapril

Pfizer has issued a voluntary nationwide recall of five (5) lots of Accupril (Quinapril HCl) tablets due to the presence of Nitroso-Quinapril.

Pfizer has issued a voluntary nationwide recall of five (5) lots of Accupril (Quinapril HCl) tablets due to the presence of Nitroso-Quinapril. Pfizer distributed the affected products to the patient (consumer/user) level.

The recall was initiated after a recent testing revealed that the tablets contained nitrosamine, Nnitroso-quinapril which was above the Acceptable Daily Intake (ADI) level.

Everyone is exposed to a given level of nitrosamines from the environment and from food but are believed to be safe at the levels typically found in food.

However, high levels of nitrosamines can be carcinogenic and thus Pfizer initiated a voluntary recall out of an abundance of caution.

Accupril tablets are indicated for the treatment of hypertension and congestive heart failure. Accupril has maintained a safety profile established over 30 years. Pfizer has not received any reports of the adverse effects associated with the use of these products.

While long term ingestion of nitrosamine is associated with cancer risk in humans, patients taking these medications are not under any immediate risk.

Patients taking Accupril (Quinapril HCl) that have purchased the affected lots should discontinue use and immediately contact their healthcare provider or pharmacist to discuss alternate treatment options.

The affected product lots were distributed to wholesalers, distributors, and retailers throughout the United States and Puerto Rico from December 2019 to April 2022. The recalled products can be identified by lot numbers listed below:

  • Accupril® (Quinapril HCl Tablets), 10 mg
  • Accupril® (Quinapril HCl Tablets), 20 mg
  • Accupril® (Quinapril HCl Tablets), 40 mg
