Neither Zantac nor ranitidine are currently available in the United States.
Zantac is a brand name heartburn medication previously available in over-the-counter (OTC) and prescription forms. Before the recall, Zantac was commonly sold as generic ranitidine.
In 2019, several manufacturers found a cancer-causing substance in the ranitidine medicines. As a result, the contaminated drugs were recalled. In response, the U.S. Food and Drug Administration initiated an investigation. The FDA investigation sought to examine the safety of ranitidine-containing drugs.
In April 2020, the agency requested that manufacturers pull all ranitidine drugs from the market. Additionally, the agency advised all consumers using over-the-counter (OTC) ranitidine drugs to stop taking the medication. Consumers taking prescription ranitidine are advised to speak with a healthcare professional immediately to get a safer alternative.
The recalls and market withdrawal stem from the cancer-causing substance N-Nitrosodimethylamine (NDMA). NDMA is a probable human carcinogen. A carcinogen is a substance capable of causing cancer. A consumer or patient could suffer significant health risks if he or she consumes too much NDMA.
How NDMA Was Discovered in Zantac
Valisure, an independent pharmacy, discovered NDMA in Zantac and ranitidine products.
Traditional pharmacies like CVS and Walgreens do not test drugs before selling them. Instead, regular pharmacies rely on manufacturer-performed safety testing. According to company founders, Valisure is different. This pharmacy dedicates itself to preventing adverse reactions caused by low quality drugs.
Valisure's NDMA Testing and Citizen Petition
Valisure independently tests each drug they sell. This testing uncovered the first evidence of NDMA in Zantac and ranitidine in early 2019. Initial tests showed NDMA in ranitidine products at more than 3,000 times the acceptable limit.
These tests also raised another alarming possibility: under the right conditions, ranitidine could produce NDMA in the stomach. If accurate, patients taking NDMA-free ranitidine are still at risk of NDMA exposure.
In September 2019, Valisure filed a citizen petition with the FDA. The petition made several statements with regard to NDMA in Zantac:
- Ranitidine is unstable as a molecule.
- Ranitidine instability could lead to generation of NDMA in the body.
- One study shows NDMA increases 400 fold in urine after ingesting ranitidine. This constitutes an amount of NDMA 500 times higher than the limit set by the FDA.
Valisure closed the petition by asking the FDA to recall all Zantac and ranitidine products. According to Valisure, any ranitidine product poses a risk of generating "very high levels of NDMA in the human body."
The FDA's Role in the Zantac & Ranitidine Recall
In response to Valisure's petition, the FDA notified the public of the potential NDMA in ranitidine products. Agency officials also mounted their own investigation into the contamination and the possibility of ranitidine creating NDMA after ingestion.
Several manufacturers recalled all ranitidine products rather than waiting for the investigations. Others did their own testing and recalled specific lots of NDMA-contaminated drugs.
The FDA's initial testing confirmed the presence of low- level NDMA contamination in some ranitidine products. They did not find levels as high as Valisure found. The levels found in some drugs were equivalent to those found in common foods. Other drug samples tested higher than the acceptable limit and were recalled as a result.
Upon further testing, the FDA eventually requested the market withdrawal of all Zantac and ranitidine. This agency requested this recall on April 1, 2020.
The FDA issued the withdrawal after tests revealed levels of NDMA increase over time in ranitidine products. This increase happens in normal storage conditions. However, storage at warmer temperatures can result in even higher levels of NDMA production.
