Invokana & Farxiga Lawsuits

Newer diabetes medications have expanded treatment options for patients, but they are not without risk. In 2010, the FDA restricted the use of Avandia after users began suffering fatal heart attacks in large numbers. In 2011, the FDA issued a warning about studies tying Actos use to bladder cancer. In 2013, diabetes drugs Byetta and Januvia were linked to inflammation leading to acute pancreatitis and pancreatic cancer.

The latest class of diabetes drugs is Sodium-Glucose Co-Transporter 2 (SGLT2) Inhibitors. Only just approved in March 2013, SGLT2 inhibitors have already been called to task for dangerous side effects. Attorneys around the country are currently evaluating potential legal claims on behalf of patients who say they have been injured by drugs like Invokana, Farxiga and Jardiance.

Conerns that diabetes drugs carry unlisted risks

Johnson & Johnson/Janssen Pharmaceuticals’ Invokana (canagliflozin) and Farxiga (dapagliflozin) are the two main drugs are primarily associated with the concern of health risks, but similar side effects may apply to other drugs in the class, such as:

  • Invokamet (Janssen Pharmaceuticals)
  • Xigduo XR (AstraZeneca)
  • Jardiance (Boehringer-Ingelheim)
  • Glyxambi (Boehringer-Ingelheim)

If you have used any of these SGLT2 inhibitor diabetes medications and suffered adverse side effects without warning, then you may be entitled to compensation for your injuries. You may have an especially compelling case if the side effects you suffered were not listed on the labeling for your drug.

Ketoacidosis claimed by users

In May 2015, the FDA issued a safety communication that these Type 2 diabetes medications may cause ketoacidosis, a potentially fatal condition where the body begins to break down fat for fuel, causing poisonous waste products called ketones to build up in the blood and urine.

Symptoms of ketoacidosis include:

  • Abdominal pain
  • Confusion
  • Dry skin and mouth
  • Fatigue
  • Flushed cheeks
  • Frequent urination
  • Fruity-smelling breath
  • Headache
  • Muscle stiffness or aches
  • Nausea and vomiting
  • Rapid breathing
  • Stomach pain
  • Thirst 

Patients suffering from any of these symptoms should seek emergency medical attention immediately to avoid kidney failure, coma and death. So far, no deaths have been reported with the use of the SGLT2 inhibitor drugs, but the danger exists.

Supporting evidence for possible SGLT2 inhibitor lawsuits

According to the FDA, 20 cases of diabetic ketoacidosis requiring hospitalization were reported from March 2013 to June 2014. Most patients had controlled blood sugar levels and had been taking the drug for only two weeks at the time of their hospitalization.

In their May 6 Quarter Watch, the Institute for Safe Medication Practices warned of over 450 adverse event report filings related to Invokana. According to their review, these injuries included:

  • 54 cases of severe dehydration or fluid imbalance
  • 54 cases of kidney failure or impairment
  • 50 cases of allergic hypersensitivity (skin rashes and facial swelling)
  • 50 cases of urinary tract infections
  • 11 cases of kidney stones

Drug trials prior to FDA approval revealed an increased incidence of fungal infections (14% among women and 3.9% among men). Furthermore, animal studies linked Invokana to long-term kidney damage, testicular or kidney cancer, and bone abnormalities, according to the report. Their opinion is that the drug hasn’t been tested in enough patients to indicate whether or not the medication has clinical benefits that outweigh the risks.

Should you file an Invokana lawsuit?

Though no lawsuits have yet been filed, attorneys are taking cases related to claims of ketoacidosis and resulting complications. Drug manufacturers have a responsibility to consumers to test their products thoroughly before releasing a drug on the market and to warn consumers of all potential risks associated with their drugs. When they fail to meet these obligations, they can be sued in the court of law to compensate victims for damages.

A successful legal settlement or jury award could cover:

  • Past, present and future medical expenses
  • Emotional pain and suffering
  • Loss of income or earning capacity
  • Wrongful death and funeral expenses

It costs nothing to have your case reviewed by a reputable lawyer. Attorney who take these lawsuits only take a fee after having secured compensation for you and your family, so there is nothing to lose and everything to gain. While you can’t undo the physical damage that has been done, pursuing a Farxiga or Invokana lawsuit may be the best way to get some reprieve from expensive medical bills related to your injuries and hold manufacturers accountable for failing to warn patients about known risks associated with their drugs.

What will happen if my attorney files an Invokana lawsuit on my behalf?

Since there have yet to be any claims filed against the makers of Invokana, it is premature to make any predictions about the litigation process. When any lawsuit is been filed, defendants may decide to settle quietly outside of court to avoid costly litigation if the evidence is stacked against them. If they are confident the case will be thrown out, they may decide to take the case to court before a judge and jury. When plaintiffs win in court, the awards to victims of pharmaceutical companies can be quite substantial.

The legal process could take years to proceed through the system, so it’s best to speak with a qualified dangerous drug attorney as soon as possible to get the ball rolling and avoid running beyond the statute of limitations in your state.
