Bristol-Myers Squibb first received U.S. Food and Drug Administration (FDA) approval for Farxiga (dapagliflozin) on January 8, 2014.
Less than a month later, AstraZeneca acquired the company’s diabetes drug portfolio, including ownership of and the rights to Farxiga. In October 2014, the FDA approved AstraZeneca’s Xigduo XR – which combines Farxiga with the diabetes drug metformin in an extended-released formulation.
Farxiga quickly became AstraZeneca’s largest selling diabetes medicine, recording $492 million in global sales in 2015.
But by then, Farxiga and other drugs in this class were linked to serious medical conditions that can lead to hospitalization, dialysis, or death.
Farxiga Linked to Medical Complications
Both Farxiga and its sister drug, Xigduo XR, have become subjects of regulatory scrutiny as these and other SGLT2 inhibitors have been linked with serious medical complications.
These conditions include:
- Diabetic ketoacidosis (DKA) – a condition involving too much acid in the blood that can result in coma or death
- Acute kidney injury (AKI)
- Serious urinary tract infections (UTIs) resulting in blood or kidney infections
- Stroke and thromboembolic events
If you have developed any of these conditions after taking Farxiga or Xigduo XR, or if a relative died from one of these conditions after taking these drugs, you may be entitled to reimbursement for medical expenses, lost wages, and other costs.

Farxiga Faces Government Scrutiny
The FDA originally denied approval for Farxiga in 2012, citing clinical trials with potentially problematic findings regarding cardiovascular, liver, and cancer risks. The agency required additional trials be submitted before reconsidering the application and subsequently approved the drug two years later.
In May 2015, the FDA warned that Farxiga and other SGLT2 inhibitors may lead to diabetic ketoacidosis (DKA), a serious condition involving elevated blood acid levels that can require hospitalization.
In December 2015, the FDA said it had “identified 19 cases of life-threatening blood infections (urosepsis) and kidney infections (pyelonephritis) that started as urinary tract infections” in patients taking SGLT2 inhibitors. The agency ordered manufacturers of Farxiga and other drugs in its class to revise label warnings reflecting possible risks of DKA and serious urinary tract infections that can result in hospitalization.
In January 2016, the FDA announced it was “evaluating the need for regulatory action” after identifying a potential signal of risk for strokes and serious blood clots in patients who had used Farxiga and other SGLT2 inhibitors via the FDA’s Adverse Event Reporting System (FAERS).
On June 14, 2016, the FDA further strengthened the warnings for Farxiga, Xigduo XR, and other SGLT2 inhibitors “to include information about acute kidney injury.” The agency also urged doctors and patients to report adverse side effects of Farxiga, Xigduo XR, and other SGLT2 inhibitors to the FDA MedWatch program.
In late 2016, the FDA again identified a potential signal of serious risk requiring an evaluation of the need for regulatory action for Farxiga and other drugs in its class following reports of patients taking Farxiga and other SGLT2 inhibitors who developed acute pancreatitis. The condition is fatal for roughly 10% of people who develop it.
In February 2017, the European Medicines Agency (EMA) concluded that another SGLT2 inhibitor, canagliflozin, may lead to lower limb amputations – particularly toes. The EMA announcement said the risk had not been seen in studies involving other SGLT2 inhibitors, including Farxiga, but “data available to date are limited and the risk may also apply to these other medicines.” The EMA is currently monitoring other studies that could define any possible risk of amputations for Farxiga and other types of SGLT2 inhibitor users.
If you have been injured after taking Farxiga or Xigduo XR, speaking with a knowledgeable attorney can help you understand your legal options. Weitz & Luxenberg can provide you with a free consultation.
Farxiga and Diabetic Ketoacidosis (DKA)
Farxiga and other SGLT2 inhibitors have been linked with risk of a patient developing DKA, which can result in a diabetic coma or death. DKA is a condition in which excess acid levels build up in the blood.
The FDA has warned patients taking Farxiga, Xigduo XR, and other SGLT2 inhibitors to not take their medicine and seek immediate medical attention if they experience symptoms of DKA.
These symptoms include:
- Difficulty breathing
- Abdominal pain
- Nausea or vomiting
- Unusual fatigue or sleepiness
Consult your doctor before stopping any prescribed medication.
If you were hospitalized for diabetic ketoacidosis, blood or kidney infections resulting from a UTI, or acute kidney injury after taking Farxiga or Xigduo XR for type 2 diabetes, Weitz & Luxenberg would like to hear from you.
Weitz & Luxenberg would also like to talk to people who suffered renal failure after taking Farxiga or Xigduo XR.
Farxiga Lawsuits & MDL
In multiple lawsuits against Bristol-Myers Squibb and AstraZeneca, plaintiffs claim they developed ketoacidosis after taking Farxiga.
Complaints filed in New York federal court claim the companies were “aware of the potential for FARXIGA and other drugs in the SGLT-2 inhibitor class to cause kidney failure prior to FARXIGA’s approval,” but failed to adequately warn patients of the risks.
In February 2017, plaintiffs asked the Judicial Panel on Multidistrict Litigation to combine lawsuits over Farxiga into a multidistrict litigation.
MDLs speed up the legal process and save time and money by consolidating cases for pretrial discovery and other pretrial proceedings.
How Weitz & Luxenberg Can Help
You may be entitled to compensation if you took Farxiga or Xigduo XR and were then hospitalized for DKA, acute kidney injury (AKI), renal failure, or for a urinary tract infection that resulted in a blood or kidney infection.
