In July 2018, the Food and Drug Administration announced a voluntary recall of several valsartan blood pressure medications because of contamination with N-nitrosodimethylamine (NDMA), a chemical that probably causes cancer. Later it found N-nitrosodiethylamine (NDEA), another similar chemical, in valsartan products. Manufacturers also recalled other drugs in the same class, including losartan and ibesartan.
The FDA estimated that about 3 million Americans take valsartan to control blood pressure or protect their hearts. The recent recall affects more than half of the United States supply of the drug, the FDA said in an Aug. 30, 2018 statement. The agency estimated that the tainted drugs have been on the market since 2014.
Not all valsartan products are included in the recall. The FDA has traced the recalled drugs to Chinese manufacturers Zhejiang Huahais and Zhejiang Tianyu as well as Hetero Labs Limited in India. The FDA’s investigation continues.
In September 2018, the FDA announced it had found another toxic chemical in tainted valsartan batches called N-nitrosodiethylamine (NDEA). Similar to NDMA, the chemical could possibly cause cancer.
The recall now includes some lots of other drugs in the same class called angiotensin II receptor blockers (ARB) after manufacturers found N-Nitroso-N-methyl-4-aminobutyric acid (NMBA) in some of these drugs in March 2019. So far, the recall includes losartan and ibesartan, according to an FDA questions and answers page.
Lawyers are filing valsartan lawsuits on behalf of people who were diagnosed with cancer after taking valsartan for more than a year or who suffered liver or kidney injuries that required an emergency room visit or hospital stay.

How to Find Out If Your Drug Is Part of the Recall
Anyone taking valsartan or a combination drug that includes valsartan should locate the name of the drug’s manufacturer and the lot number either on the prescription bottle label or in the warning insert that accompanies the medication. Then, check with your pharmacist or search the FDA’s recall list for the manufacturer and lot number.
The FDA also uses a National Drug Code to track products. The FDA’s list includes the NDC codes for all recalled valsartan products. Normally, your prescription bottle from the pharmacy will not contain this information. Your pharmacist should be able to check these codes for you.
What Should I Do If My Drug Is Recalled?
If your valsartan manufacturer is a part of the recall, do not stop taking your medication. Suddenly stopping your medication may lead to health problems. First, talk to your doctor about your treatment options.
Next, search for your drug’s manufacturer in the FDA’s Drug Recalls database. Some manufacturers provide guidance in the event of a medication recall. For example, Torrent Pharmaceuticals Limited lists all the lots and products included in its recall. It also provides contact information and instructions for patients.
If you cannot find information on the FDA’s website, talk to your pharmacist. Don’t throw away your medication until you have your new medication. Your pharmacist can offer instructions for disposing of old medication.
Alternatives to Valsartan
Several blood pressure drugs may be a suitable alternative to valsartan. There are drugs in the same class as valsartan, and they work the same way. You may also be able to get valsartan from a manufacturer that is not on the recall list.
Ask your doctor about your treatment options. Each of these medications has its own risks or side effects.
- Losartan potassium
- Prazosin hydrochloride
- Doxazosin mesylate
- Hydralazine hydrochloride
NDMA Cancer Risk
The FDA recalled some valsartan products because it found traces of NDMA, a chemical that can cause tumors in animals and probably causes cancer in humans. Cancer is not a typical valsartan side effect.
“We estimated that if 8,000 people took the highest valsartan dose (320 mg) from NDMA-affected medicines daily for four years (the amount of time we believed the affected products had been on the U.S. market), there may be one additional case of cancer over the lifetimes of these 8,000 people beyond the average cancer rate among Americans,” FDA Commissioner Scott Gottlieb said in a statement.
In some studies, researchers found a positive link between NDMA intake and gastric and colorectal cancer, according to Health Canada’s Guidelines for Canadian Drinking Water Quality released in 2011.
On Feb. 28, 2019, the FDA posted its interim limits for NDMA, NDEA and NMBA in angiotensin II receptor blockers. The FDA calculated its acceptable limits based on a 1 in 100,000 cancer risk after 70 years of exposure.
- NDMA — 96 nanograms per day; 0.3 parts per million
- NDEA — 26.5 nanograms per day; 0.083 parts per million
- NMBA — 96 nanograms per day; 0.3 parts per million
