Did you or a loved one take the drug Valsartan for high blood pressure? N-nitrosodimethylamine (NDMA) and/or N-Nitrosodiethylamine (NDEA) contamination may have occurred with some batches of Valsartan, exposing patients taking the drug to a known chemical carcinogen. Lawsuits are being filed against manufacturers of Valsartan who may have distributed tainted batches and sold the drug to consumers. Those affected by NDMA or NDEA found in Valsartan may experience liver damage, tumors and cancer. If you or a family member think you have been contaminated, contact our Valsartan Lawsuit Claims Lawyers at Ligori & Ligori, Injury Lawyers in Florida.
NDMA, a known carcinogen, is not domestically manufactured in the United States, nor were the tainted batches of Valsartan contaminated with this cancer-causing chemical produced within U.S. borders. Instead, it is suspected that pharmaceutical companies may have sourced Valsartan from international suppliers, including the Chinese pharmaceutical company Zhejiang Huahai Pharmaceuticals and the India-based company Hetero Labs Limited, both of which were found to have produced tainted batches containing NDMA. Despite the potential for short-term use of Valsartan, emerging evidence suggests that even brief exposure to NDMA-laced Valsartan formulations may yield enduring repercussions, particularly concerning liver health. The cumulative impact of prolonged exposure to NDMA can significantly heighten the risk of liver damage, carcinogenesis and the development of malignant tumors, underscoring the gravity of the health risks associated with contaminated medications.
Symptoms of NDMA Overexposure
Those who have had overexposure to NDMA may experience immediate and long-term symptoms. Some of the known signs of NDMA exposure include:
- Abdominal cramping and pain
- Headaches
- Vomiting and nausea
- Dizziness
- Fever
- Enlarged and reduced function of the liver
- Kidney and lung dysfunction
- Jaundice
Over time, NDMA exposure can increase the risk of liver damage, cancer and tumors. In some cases, you may not have had immediate symptoms of NDMA overexposure but still may have long-term health problems resulting from taking tainted Valsartan.
