Blood pressure drug recall expands again
The US Food and Drug Administration says another heart medicine is being voluntarily recalled after tests showed that it was tainted with a potential cancer-causing chemical.
The new recall of losartan potassium hydrochlorothiazide is sold by the company Sandoz. The voluntary recall only involves the 100 milligram/25 milligram tablets, it does not involve the other versions of the drug, sometimes sold under the brand names Hyzaar. If you take Sandoz’s losartan potassium, look on the bottle for the lot number. If it has the lot number JB8912, then you have the recalled pills. Patients use these drugs to keep their high blood pressure in check.
The drug is being recalled because the active ingredient has tested positive for N-Nitrosodiethylamine or NDEA, a suspected human and animal carcinogen that is used in gasoline as a stabilizer for industry materials and as a lubricant additive, according to the National Institutes of Health.
The ingredient was made by Zhejiang Huahai Pharmaceutical Company Co. Ltd. The FDA placed the Chinese company on an import alert at the end of September, meaning all of its active pharmaceutical products and finished products will not be permitted to enter the United States. The FDA made that decision after an inspection of the facility.
Several pills that contain valsartan, another drug used by heart patients, have been under a recall since July. The drugs were tainted with NDEA or NDMA, N-nitrosodimethylamine, an impurity that is also considered a possible carcinogen by the US Environmental Protection Agency.
NDMA is an organic chemical used to make liquid rocket fuel and is a byproduct of manufacturing some pesticides and processing fish. It can be unintentionally introduced into manufacturing through certain chemical reactions.
The FDA is testing all heart drugs known as ARBs for these impurities.
The latest recall impacts less than 1% of the total losartan drug products in the US market, according to the FDA.
If your drug is on the recall list, the FDA suggests taking it until your doctor or pharmacist provides a replacement. Because not all valsartan and irbesartan drugs are involved in the recall, you might be able to switch to a version by another company.
