Zantac, generically known as ranitidine, has been a popular heartburn medication for decades. The medication, available by prescription or over-the-counter, has been a go-to treatment for heartburn, ulcers, and acid reflux. Despite its common use as a popular heartburn medication, Zantac has been linked to serious health concerns, including cancer. This is because the active ingredient in Zantac, ranitidine, contains N-nitroso dimethylamine (NDMA), which is a probable human carcinogen. The presence of NDMA prompted the FDA to recall the drug in 2020. Unfortunately, many people have used Zantac for years without knowing the Zantac cancer risk, the types of cancers associated with its use, and the Zantac cancer symptoms to watch for. By understanding your Zantac cancer risk and recognizing what Zantac cancer symptoms are, you can take proactive steps to protect your health and seek justice.
Zantac and its generic equivalent are histamine-2 receptor antagonists (H2RA) used to reduce stomach acid production. Concerns arose when testing revealed that ranitidine could break down into NDMA, a chemical classified as a probable carcinogen by the World Health Organization along with the FDA. What made matters even worse was that the FDA found that NDMA levels in Zantac increased under typical storage conditions and were also worsened by exposure to higher temperatures, leading to a significant Zantac cancer risk in long-term users.
These findings prompted the FDA to recall Zantac and other ranitidine-based products and concern about the safety of the drugs continued.
Since 2020, thousands of individuals have filed lawsuits after developing cancer and using Zantac for years. These legal campaigns have raised awareness about Zantac cancer risk and helped bring justice to people who have been affected.
Both research and observational studies have identified several cancers potentially associated with the Zantac cancer risk as a result of the NDMA exposure. While ongoing research continues to examine the exact mechanisms that show how NDMA exposure causes cancer, the following cancers have been most frequently linked to ranitidine use:
Cancer of the colon or rectum, or colorectal cancer, is one of the most robustly linked cancers to Zantac use. Studies have shown the development of cancerous polyps in the large intestine may arise after Zantac use. Zantac cancer symptoms for colorectal cancer include:
Studies have also linked bladder cancer to Zantac cancer risk, with long-term users of Zantac reportedly facing a 43 percent higher risk of bladder cancer when compared to non-users. Zantac cancer symptoms that may be associated with bladder cancer include:
NDMA harms the liver in animal studies and studies have also linked NDMA consumption with liver damage and an increased risk of liver cancer. Zantac cancer symptoms for liver cancer can include:
Studies have found that ranitidine, the key chemical makeup of Zantac, more than doubled the risk of ductal carcinoma, a common type of breast cancer in both men and women. Zantac cancer symptoms for breast cancer may include:
Other cancers have been associated with Zantac use, including stomach, esophagus, pancreas, kidneys, and even testicular cancer in some cases. These cancers may present with varied Zantac cancer symptoms, such as:
While studies have shown associations between Zantac and cancer, some studies complicate the findings. For example, a 2023 study published in JAMA Network Open found no significant increase in overall cancer risk compared to other H2RAs, suggesting that the risk may depend on factors like duration of use and NDMA exposure levels.
The Zantac cancer risk comes from NDMA, a known potent carcinogen. NDMA can form when ranitidine breaks down under normal storage conditions. This breakdown happens over time or when exposed to heat.
NDMA has been found to cause DNA damage and promote tumor growth. Prolonged exposure increases the likelihood of cancer development.
The FDA set a daily NDMA intake limit of 96 nanograms. However, tests revealed alarming results. Some Zantac doses contained up to 2,500,000 nanograms, far exceeding safe levels.
This risk is compounded for individuals who took Zantac regularly. Taking it for months or years creates cumulative NDMA exposure. This cumulative exposure heightens the Zantac cancer risk.
Factors such as storage conditions, manufacturing processes, and even the body’s gastric environment may contribute to NDMA formation. For example, studies have shown that NDMA levels in the urine of Zantac users increased 400-fold after ingestion.
It’s critical to be aware of Zantac cancer symptoms for early detection and treatment. Since the cancers linked to Zantac vary, symptoms depend on the affected organ. Here’s a summary of key Zantac cancer symptoms to monitor:
General Symptoms: Unexplained weight loss, fatigue, or chronic pain may indicate cancer and should prompt a visit to a healthcare provider.
Breast Changes: Lumps, skin changes, or nipple abnormalities may suggest breast cancer.
Liver-Related Symptoms: Jaundice, chalky stools, or right-sided abdominal pain could point to liver cancer.
Gastrointestinal Symptoms: Blood in the stool, changes in bowel habits, abdominal pain, or difficulty swallowing may signal colorectal, stomach, or esophageal cancer.
Urinary Symptoms: Blood in the urine or painful urination could indicate bladder or kidney cancer.
If you have had long-term exposure to Zantac or its generic equivalent and have Zantac cancer symptoms, consult a doctor immediately.
Since the discovery of NDMA in Zantac, thousands of lawsuits have been filed against its manufacturers, including Sanofi, GlaxoSmithKline, and others. The cases allege that these companies failed to warn consumers about the Zantac cancer risk.
If you or a loved one developed cancer after using Zantac, you may be eligible to seek compensation through legal action. Thousands of cases have been filed and many have been settled, but a number of them are still pending in Florida.
Individuals who meet the following criteria may be eligible to file a Zantac lawsuit:
Legal action not only helps individuals obtain compensation but also holds manufacturers accountable, potentially preventing future harm. If you’re unsure whether you qualify, an experienced personal injury lawyer can help determine if a case is viable.
