Drug Companies Investigated For Failing To Disclose Zantac Risks

September 30, 2020 / 8:37 am

At Colson Hicks Eidson, we have regularly discussed the cancer risks posed by Zantac and other generic forms of ranitidine. Over the last year, these medications have been recalled, and major companies have pulled them from their shelves. Now, federal investigators are looking into whether two drugmakers may have known about a probable carcinogen in Zantac and other forms of ranitidine but failed to disclose that information with the government.

Us Department Of Justice Investigating Two Drugmakers Over Zantac

When pharmaceutical companies or manufacturers have information related to their products being unsafe, they cannot legally hide this information. That is why the US Department of Justice is investigating whether GlaxoSmithKline and Sanofi violated the False Claims Act by possibly failing to disclose the presence of n-nitrosodimethylamine (NDMA) inside of Zantac and the generic forms of the heartburn medication.

NDMA has been classified as a probable human carcinogen. In April of 2020, the US Food and Drug Administration (FDA) requested that all manufacturers remove the prescription and over-the-counter ranitidine products from the market.

GlaxoSmithKline is the original manufacturer of Zantac, though Sanofi currently holds the rights to the Zantac brand name in the United States. GlaxoSmithKline and other drug companies currently sell the generic form of ranitidine in the US. If these drugmakers knew of the dangers of Zantac and the generic forms of the medication and failed to disclose this information to the federal government, they could face significant repercussions.

The presence of NDMA in these medications was discovered by a private laboratory that routinely tests prescription medications. These labs discovered that Zantac 150 mg tablets could contain as much as 2,500,000 nanograms of NDMA. However, humans can only safely consume 96 nanograms of NDMA per day, according to the FDA.

There may be various types of cancers linked to Zantac and other ranitidine products, including the following:

  • Stomach Cancer
  • Liver Cancer
  • Bladder Cancer
  • Small Intestine Cancer
  • Colorectal Cancer
  • Esophageal Cancer
  • Prostate Cancer
  • Lung Cancer
  • Testicular Cancer
  • Ovarian Cancer
  • Uterine Cancer
  • Nasal/Throat Cancer
  • Thyroid Cancer
  • Pancreatic Cancer
  • Kidney Cancer
  • Brain Cancer

If you or somebody you love has been diagnosed with cancer, and you believe the illness was caused by taking Zantac or another form of ranitidine, contact an attorney immediately. At Colson Hicks Eidson, our nationally-recognized product liability lawyers are actively involved in helping clients with these cases. Our goal is to investigate your case in order to determine whether you are entitled to the following:

  • Compensation for medical bills related to your cancer diagnosis
  • Lost income if you are unable to work due to your diagnosis
  • Pain and suffering damages
  • Loss of enjoyment of life damages
  • Possible punitive damages against the makers of the harmful medication

Colson Hicks Eidson, a leading trial law firm, is proud to announce its relocation to the Penthouse of the South Tower at Douglas Entrance in Coral Gables. This move marks an important milestone for the firm, which has represented clients in local, national, and international matters for more than 55 years. The new office is located within Douglas Entrance, home to the historic gateway La Puerta del Sol (“The Gate of the Sun”), and is surrounded by Mediterranean-style architecture, lush landscaping, and expansive courtyards. With its picturesque, Spanish-walled-city appearance, Douglas Entrance provides a distinctive office environment in Coral Gables, and the firm’s name will soon adorn the top of the South Tower.

The space holds personal significance for Managing Partner Dean Colson, who explains: “For those of us who grew up in the Gables in the ‘50s and ‘60s, the original Douglas Entrance was very much a part of our lives – it was the working home for many of the doctors, lawyers, architects, and other professionals who lived south of downtown Miami. Our move reflects not only our firm’s growth, but our ongoing dedication to our clients and the Coral Gables community. It is reminiscent of our decision 25 years ago to restore the building that is now Books & Books and secure its historic designation—a choice that helped preserve the character of Coral Gables. The firm remains committed to doing the right thing for our community.”

Colson Hicks Eidson moved into its new space in December 2025 with the assistance of Will Morrison of CBRE. According to Dean, “Will’s expertise, vision, and patience made this deal possible. G. Alvarez Studio ensured that the design of our floor was executed perfectly.”
