(CNN) – Some common heartburn and acid reflux medications may be contaminated with a cancer-causing impurity.
The Food and Drug Administration says the drug Zantac and its generics contain small amounts of a substance known as NDMA.
It’s the same probable carcinogen that prompted a July recall of several blood pressure medications.
An FDA spokeswoman told USA Today the discovery isn’t prompting a recall and says people shouldn’t panic, but the agency says it’s a good idea to switch to another over-the-counter drug.
Those on a prescription version should talk to their doctor or pharmacist.
