FDA says drug makers have recalled a blood pressure medicine tainted
with a cancer-causing chemical
[October 31, 2025]
The U.S. Food and Drug Administration says drug makers have recalled
more than a half-million bottles of the blood pressure medication
prazosin hydrochloride over concerns it may include a cancer-causing
chemical.
New Jersey-based Teva Pharmaceuticals USA and drugs distributor
Amerisource Health Services issued voluntary nationwide recalls earlier
this month of more than 580,000 bottles of various strengths of
prazosine capsules, according to the FDA.
Doctors prescribe prazosin, which relaxes blood vessels, to help lower
blood pressure. It also is sometimes prescribed for nightmares and other
sleep disturbances caused by post-traumatic stress disorder.
The FDA said in enforcement orders posted online that it has given the
affected lots of the drug a Class II risk classification because some of
the recalled medication may have nitrosamine impurities that are
considered potentially cancer causing.

 According to the FDA, N-nitrosamine
impurities are a class of potentially cancer-causing chemicals that
can form during manufacture or storage of a drug.
