Last week, over half a million bottles of prazosin hydrochloride, a blood pressure medication, were recalled by drug manufacturer Teva. The reason for the recall was because testing revealed higher-than-acceptable levels of impurities known as N-nitrosamines. All of this information was released by the U.S. Food and Drug Administration (FDA) via an enforcement report.
The enforcement report detailed a Class 2 event, indicating that the affected medications, “…may cause temporary or medically reversible adverse health consequences or where the probability of serious adverse health consequences is remote.” The recall is for 1, 2, and 5 milligram (mg) doses of prazosin hydrochloride. This medication is an alpha-blocker that is FDA-approved to help treat high blood pressure. Some people also use prazosin hydrochloride to treat benign enlarged prostate, nightmares related to PTSD, and temporary discoloration in the extremities due to cold exposure.
You can check the lot number on your prescription to see if it was included in the FDA’s list. The FDA and Teva did not indicate whether consumers should throw out prazosin included in this recall. For the Class 2 recalls, however, the FDA states that people can typically keep taking the recalled medications unless otherwise stated by the manufacturer. That is entirely your decision to make, as stopping medication in certain instances may be more harmful. Consult your doctor or pharmacist if you have questions regarding your medication.
What Are N-Nitrosamines?
These chemicals commonly exist in water and foods, including cured and grilled meats, dairy, and vegetables. Most people are exposed to some amount of nitrosamines, but that depends on diet and other factors.
The N-nitrosamine impurities can form during the manufacturing or storing processes of a drug. According to the FDA, the N-nitrosamine impurities may increase the risk of cancer if people are exposed to them above acceptable levels and over long periods of time. If you happened to take a medication with nitrosamine levels at or below accepted levels, every day for 70 years, you wouldn’t be expected to have a higher cancer risk. As that is an estimation, you may not want to take that chance.
