Zantac should be removed from market ‘immediately,’ FDA says
All over-the-counter and prescription ranitidine medications -- commonly known by the brand name Zantac -- should be removed from the market "immediately," the U.S. Food and Drug Administration (FDA) said Wednesday.

CORONAVIRUS RESOURCES: Everything You Need to Know
Ranitidine medications, which have been used to treat heartburn, have a contaminant called N-Nitrosodimethylamine (NDMA) that could cause cancer, according to a release from the FDA.
The agency said it has been investigating NDMA in ranitidine and found the contaminant increases over time "and may result in consumer exposure to unacceptable levels of this impurity."

According to the release, ranitidine products will no longer be used in medications.
"The FDA is committed to ensuring that the medicines Americans take are safe and effective," Dr. Janet Woodcock, director of the FDA’s Center for Drug Evaluation and Research said in a statement.

"We make every effort to investigate potential health risks and provide our recommendations to the public based on the best available science," Woodcock added. "We didn’t observe unacceptable levels of NDMA in many of the samples that we tested. However, since we don’t know how or for how long the product might have been stored, we decided that it should not be available to consumers and patients unless its quality can be assured. The FDA will continue our efforts to ensure impurities in other drugs do not exceed acceptable limits so that patients can continue taking medicines without concern."
Even though low levels of NDMA are commonly ingested in food and water -- and do not increase the risk of cancer -- higher levels of exposure to NDMA could increase a person’s risk of cancer, the FDA release said.
Independent laboratory testing found NDMA in ranitidine, which the FDA first found out about in 2019, the FDA said. The agency did its own tests and also found low levels of the contaminant.
It warned the public of potential risks in September 2019 but "did not have enough scientific evidence to recommend whether individuals should continue or stop taking ranitidine medicines" at the time.
More recent studies by the FDA found that NDMA increases over time under regular conditions, but in higher temperatures the impurity increases "significantly."
"The testing also showed that the older a ranitidine product is, or the longer the length of time since it was manufactured, the greater the level of NDMA," the release said. "These conditions may raise the level of NDMA in the ranitidine product above the acceptable daily intake limit."
Aside from requesting manufacturers to remove ranitidine products from the market, the FDA advised that consumers "stop taking any tablets or liquid they currently have, dispose of them properly and not buy more."
Other FDA-approved heartburn medications include famotidine (known as Pepcid), cimetidine (known as Tagamet), esomeprazole (known as Nexium), lansoprazole (known as Prevacid) or omeprazole (known as Prilosec) -- none of which have NDMA in them, according to the release.
