Why is the Dept. of Justice Investigating Zantac Maker?

December 23, 2020 / 7:16 am

Zantac and generic forms of this medication, both prescription and over the counter, have faced significant recalls over the last year. Now, The US Department of Justice (DOJ) is investigating two Zantac manufacturers. The DOJ is attempting to determine whether or not the drug manufacturers violated federal laws while selling the medication. Here, we want to discuss this ongoing investigation as well as give a brief overview of the Zantac recall.

Why have Zantac and generic ranitidine been recalled?

Zantac and other ranitidine medications have faced massive recall over the last year after investigations uncovered unsafe levels of N-Nitrosodimethylamine (NDMA), a probable human carcinogen. In a statement released on April 1, 2020, The US Food and Drug Administration (FDA) asked that all Zantac and ranitidine products be removed from the market immediately.

According to the FDA, “The agency has determined that the impurity in some ranitidine products increases over time and when stored at higher than room temperatures and may result in consumer exposure to unacceptable levels of this impurity.”

Testing continued to show that NDMA levels increase inside these medications under normal storage temperatures and conditions, though the level of NDMA significantly increases at higher storage temperatures.

What is going on with the DOJ investigation?

The Department of Justice is investigating GlaxoSmithKline (GSK) and Sanofi, two of the Zantac manufacturers. GlaxoSmithKline is the original manufacturer of Zantac, and Sanofi currently holds the rights to Zantac brands in the United States. Both of these companies currently sell generic forms of ranitidine throughout the country.

Specifically, the DOJ is seeking to have several questions answered:

  • When did these manufacturers learn about unsafe NDMA levels in the medication?
  • When did the manufacturers learn that Zantac’s active ingredient can breakdown in the stomach, creating additional NDMA?
  • Did the manufacturers conceal cancer risks associated with Zantac?

Answers to these questions could reveal potential violations of the False Claims Act (FCA). The FCA was signed into law in the 1800s and made it illegal for manufacturers to provide sub-standard goods and services to the US government. Typically, the FCA is referred to as a whistleblower law. If it is discovered, through the course of the investigation, that these companies knew about the dangers posed by Zantac and the generic forms of the medication, and failed to disclose this information to the government, they could face significant repercussions.

Dean Colson, managing partner of the firm, commented: “Zach is a valued member of the firm and a respected figure in the South Florida legal community. His practice focuses on complex commercial litigation and products liability matters, representing both plaintiffs and defendants in high-stakes disputes across a wide range of industries. He is known for his strategic judgment, rigorous advocacy, and ability to manage cases involving significant financial exposure and novel legal issues.”

During his six years at Colson Hicks Eidson, Zach has worked with Bob Martinez, Curtis Miner, and other firm partners to secure four nine-figure judgments against Fortune 500 companies, obtain dismissals with prejudice on behalf of multiple Fortune 500 defendants, and successfully represent clients before arbitral, state, and federal forums, at trial and on appeal.

According to Senior Partner Bob Martinez: “Zach has been the indispensable force behind our victories in several high-stakes matters over the past seven years, combining unique legal talent with exceptional dedication and service to our clients.”

“Having spent multiple weeks shoulder-to-shoulder with Zach in trial, I am eager to have him as a teammate on any type of trial we need to suit up for,” added partner Curtis Miner.

Zach joined the firm following a federal judicial clerkship with the Honorable Robert N. Scola, Jr., former United States District Judge for the Southern District of Florida. Zach is a 2016 graduate of the University of Miami School of Law. He completed his undergraduate studies at Oberlin College in 2011 and earned a master’s degree in marine affairs and policy from the University of Miami Rosenstiel School of Marine and Atmospheric Science in 2012.

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.”
