Another blood pressure medicine is pulled from the market for trace amounts of a cancer-causing element.

The Food and Drug Administration has announced a recall for another blood pressure medication. The makers of Losartan Potassium/Hydrochlorothiazide combination tablets, Macleods Pharmaceuticals are participating in the voluntary recall. The drug may contain trace amounts of an element called N-nitrosodiethylamine. Patients taking this drug should not stop taking the medication, but should follow instructions for returning the affected lot numbers.

What is N-nitrosodiethylamine (NDEA)?

N-nitrosodiethylamine is a naturally occurring substance that can be found in drinking water, food, as a by-product of industrial processes, and in the air. The substance has been classified as a human carcinogen by the International Agency for Research on Cancer. The detection of trace amounts in certain lots of the Losartan Potassium/Hydrochlorothiazide prompted Macleods Pharmaceuticals to recall the product.
