(HealthDay)—After the U.S. Food and Drug Administration announced last week that certain brands of blood pressure medicines contained a carcinogen and were being recalled, many patients may wonder what’s next for their cardiovascular care.

The FDA said it mandated the recall because valsartan medicines from a Chinese manufacturer, Zhejiang Huahai Pharmaceuticals, were found to contain N-nitrosodimethylamine (NDMA), “a probable human carcinogen.”

The agency noted that not all valsartan medicines for high blood pressure or heart failure are being recalled, only the affected brands.

“To determine whether a specific product has been recalled, patients should look at the drug name and company name on the label of their prescription bottle. If the information is not on the bottle, patients should contact the pharmacy that dispensed the medicine,” the FDA said in an agency news release.

The recalled products include valsartan distributed by: Major Pharmaceuticals, Solco Healthcare and Teva Pharmaceuticals Industries Ltd. It also includes valsartan/hydrochlorothiazide formulations distributed by Solco Healthcare and Teva.

But even if you are taking one of the recalled meds, don’t stop using it immediately. The FDA stressed that “because valsartan is used in medicines to treat serious medical conditions, patients taking the recalled valsartan-containing medicines should continue taking their medicine until they have a replacement product.”

One cardiologist agreed with that advice.

“The best remedy we are telling our patients is to contact their pharmacist and request they take an appropriate brand that does not have this impurity,” said Dr. Satjit Bhusri, a heart specialist at Lenox Hill Hospital in New York City.

“There are many other substitutes for this medication, and that is an important discussion all patients should have with their physician,” Bhusri said.

He pointed out that “patients on the heart failure combo drug Entresto, which contains valsartan, have not been affected.”

Dr. Michael Goyfman directs clinical cardiology at Northwell Health’s Long Island Jewish Forest Hills in New York City. He stressed that none of this should undermine people’s faith in valsartan.

“The contaminant itself is the issue; valsartan otherwise remains an effective medication to treat high blood pressure and heart failure,” Goyfman said.

And he agreed that no one should stop taking the recalled drugs immediately.

“Doing so may worsen their blood pressure and can lead to worsening heart failure, a stroke or a heart attack, which are possibly more significant risks than those from NDMA exposure,” Goyfman said.
