Certain lots of irbesartan are being recalled by SciGen because they contain an industrial chemical that's a suspected carcinogen, CNN reported.
The recalled drugs have "Westminster Pharmaceuticals" and "GSMS Inc." on the label.
Another heart drug, valsartan, was recalled recently due to contamination with possible cancer-causing chemicals, CNN reported.
Not all medicines that contain valsartan or irbesartan are being recalled. The new recall covers only about 1 percent of irbesartan drug products available in the United States, according to the FDA.
