Zantac Cancer Risk Suspected After Known Carcinogen Found By FDA
Following an alarming discovery announced by the FDA, the lawyers at Saiontz & Kirk, P.A. began investigating the potential for Zantac lawsuits after the known human carcinogen N-Nitrosodimethylamine (NDMA) was detected in the widely used heartburn drug.
At the time, our firm also represented individuals nationwide in valsartan lawsuits involving exposure to the same chemical, which had previously contaminated large portions of the U.S. supply of that blood pressure medication.
While early findings about the Zantac cancer risk were still under review, our legal team began evaluating potential claims involving several forms of cancer potentially linked to NDMA exposure from contaminated ranitidine products, including:
- Bladder Cancer
- Pancreatic Cancer
- Esophageal Cancer
- Stomach Cancer
- Liver Cancer
Our firm is no longer accepting new Zantac cases. The information provided on this page is for informational and historical reference only
Zantac Cancer Warning
This investigation was launched after the FDA issued a warning, indicating that there was evidence Zantac may contain cancer-causing impurities. The statement indicated that levels of N-nitrosodimethylamine (NDMA) were detected from laboratory tests of certain versions of the drug.
Zantac is part of a class of medications known as H2 receptor antagonists, which also includes Pepcid AC and Tagamet. It was commonly prescribed to treat gastroesophageal reflux disease (GERD), heartburn with acid indigestion, and stomach ulcers.
At the time of the initial warning, the FDA stated that the investigation was in its early stages. Although the first samples tested showed low levels of NDMA, it remained unclear how widespread the contamination was or how long users may have been exposed—factors that could significantly influence cancer risk.
Similar concerns had already emerged earlier that year with NDMA contamination in blood pressure medications like valsartan, irbesartan, and losartan, where levels of the impurity varied considerably from batch to batch.
The NDMA contamination in Zantac was first reported by Valisure, an online pharmacy that conducted independent testing of the medication.
Zantac Case Evaluations Provided
As part of the investigation into potential Zantac cancer lawsuits, individuals who were diagnosed with cancer following long-term use of the medication were invited to submit information for review. All claims were evaluated on a contingency fee basis, with no out-of-pocket expenses or legal fees unless a recovery was obtained.
2022 Update: Following the initial cancer warnings related to Zantac, our firm reviewed thousands of claims and assessed the available medical literature linking ranitidine to specific types of cancer. As a result, our legal team narrowed the scope of accepted cases to include only those involving:
Actively Pursued Cancer Diagnoses:
- Bladder Cancer
- Esophageal Cancer
- Liver Cancer
- Pancreatic Cancer
- Stomach Cancer
Previously Investigated Cancer Diagnoses (Not Pursued):
- Prostate Cancer
- Breast Cancer
- Kidney Cancer
- Colorectal Cancer (colon or rectal)
- Lung Cancer

I acquired the form of cancer called Lupus as a result of the use of Ranitidine, the generic form of Zantac. I need an attorney to represent me in a case against the maker of this drug.

Why do doctor’s give you RX for one health problem and try to cause other health problem later on in your life. Sorry you get screwed either way. I took Wal-Mart brand substitute Zantac 150 and Pepcid though out my life. I burned my esophagus showing in my endoscopy took
1 year to correct that with omeprazole bad for bones and I also take losartan on a regular basic for high blood pressure. My brother has a history of heartburn and he got esophagus cancer. He properly took these Zantac and others heartburn meds.

I have been taking Ranitidine for over 15 years and just found out the information about the recall & problems it can cause. I am wondering if there is a screening available. I recently found a mass on my body and was concerned before that. Please, any help would be greatly appreciated.

I had taken Zantac on and off and was just recently diagnosed with Bladder Cancer. For the most part I had been taking Nexium, has there been any links to nexium in causing cancer? My medical records show me using nexium for years.

I have taken Ranitidine on and off for many years. Most recently I take it daily for over a year as prescribed by my doctor. In September 2019 I was diagnosed with colon cancer and had surgery to remove the cancer on October 16, 2019. Thankfully the cancer was caught early and did not spread, I do not need chemo or radiation or any further treatment. I should be happy which I am however I am mystified. Just 7 months earlier I was diagnosed with breast cancer. I had a masectomy removing my right breast but again I did not need any further treatment except for a pill I have to take daily for 5 years. In the year proceeding my diagnosis of colon cancer I had 4 or more colonoscopies which I was told were clean. I dont know if the Zantac possibly caused the colon cancer but after reading the information here I became curious. I also take Lowsartan for high blood pressure. I have taken Nexium in the past. Im wondering how a persons cancer can be proven to be caused by a certain drug.

I have taken zantac for years and tagamet before that. I have taken nexium, but when it went across the counter, my insurance wouldn’t pay and I can’t be afford it. A doctor recently told me to take 2 maximum strength zantac a day. I have terrible reflux problems. I can’t sleep because of it. Now I’m extremely concerned. I’m going to contact my doctor as soon as possible.

I’ve been taking Generic Zantac for years. I heard about it causing Cancer and had to tell my pharmacy to quit filling it and call my doctor for something else. She has prescribed Pepcid. I have needed to go and get a colonoscopy for a cpl years now. But I noticed about a year now that my urine smells strong after peeing. Like a bonfire smells of burnt wood. Very Alarming! My doctor told me to drink more water. I’m really concerned now with hearing about these cancers. Is there a specific test I can take to see if I have Cancer?

I been prescribed zantac since 2009 or so and was found to have prostate cancer in 2016. I have had my prostate removed because of the cancer it my whole life changed because of it. My wife hates it and wished the radiation would have been better for me. I too wished my manhood was normal. I think I have already contacted this firm. May want to check this info first before contacting me.
