How Much Are Invokana Cases Worth?

The claims filed against Janssen Pharmaceuticals for Invokana injuries usually seek compensation for medical bills, lost wages, future expenses, pain and suffering. These can vary from less than $50,000 to more than $1 million in death cases.

Since every case is unique, it is difficult to predict the value without a complete review of medical records and gathering facts from the injured party.

For this reason, it is recommended that patients who suffered complications while taking Invokana speak with a lawyer to determine if they qualify for a case and what it may be worth.

Fortunately, it costs nothing to file a claim, and the injured patient is only responsible for attorney’s fees and costs if they receive an award in their case.

Filing an Invokana lawsuit is simple. After a short, free telephone conference to see if your case qualifies, your lawyer will collect medical records to begin building a case for mediation or trial. There is no cost to you unless you receive compensation.


Invokana is a type 2 diabetes drug of the sodium-glucose transport-2 protein (SGLT2) inhibitor class. These drugs, also known as gliflozins, work by blocking the kidneys’ ability to absorb most of the sugar in the blood, which is instead flushed out in urine.

Unfortunately, the FDA has uncovered several dangerous side effects (link to side effects page) of Invokana that weren’t disclosed by the manufacturer when it was released in 2013. These complications, including kidney damage, ketoacidosis, pancreatitis and leg and foot amputations, have affected thousands of patients that were unaware of the risks.

What began in 2015 as a single Invokana lawsuit filed by a California woman hospitalized for ketoacidosis has now grown to more than 1,000 cases consolidated in a special federal court and other state courts around the country.

In addition to ketoacidosis, hundreds have also filed an Invokana lawsuit for amputation (link to amputation page), kidney damage, blood clots or stroke.If you or a loved one suffered hospitalization for ketoacidosis, amputation or kidney damage, you may be eligible for compensation.

Since the FDA approved Invokana in 2013, the agency has added numerous warnings based on reports of side effects from patients. In most cases, the manufacturer, Johnson & Johnson, until required by the FDA, didn’t mention these dangerous complications.

Beginning in 2015, the FDA added new warnings for dangerous blood toxicity (ketoacidosis) and kidney damage side effects of Invokana. Later that year, authorities added urinary tract infections and stronger warnings for bone fractures to the list of dangers.

By 2016, the FDA’s Adverse Event Reporting System (FEARS) recorded an alarming trend of acute pancreatitis in patients taking Invokana.

Finally, studies that were designed to measure risks for heart attacks and kidney disease picked up on the latest side effects of Invokana: patients were twice as likely to suffer a leg, foot or toe amputation while taking the drug.


Lawsuits against Janssen Pharmaceuticals/J&J for injuries caused by Invokana allege that the company was negligent in: failing to properly test the drug to ensure its safety, concealing the dangers from the FDA, misstating the benefits and risks of Invokana, and failing to adequately warn patients of the dangerous side effects.

These claims apply to most patients that suffered hospitalization or serious complications while taking Invokana, especially those who were affected by:

If you or a family member experienced one of these side effects after taking an SGLT2 drug, you may be eligible to file an Invokana lawsuit.

It is important to note, however, that your right to file a claim may be limited by the date you took the drug, your date of injury, and the specific laws of your state. Therefore, you should speak with a lawyer as soon as possible to learn your options.

On December 7, 2016, the Judicial Panel on Multidistrict Litigation entered an order consolidating more than 100 similar Invokana lawsuits to Multidistrict Litigation (MDL) 2750, under the direction of U.S. District Judge Brian Martinotti in the District of New Jersey.

The case is formally known as In RE: Invokana (Canagliflozin) Products Liability Litigation. While this MDL court is similar to an Invokana class action lawsuit, it differs slightly in that the cases are filed and maintained separately, giving each plaintiff more control over major case decisions and who will represent them.

As of January 2018, 1,004 claims have been filed or transferred to the Invokana MDL, representing a variety of injuries. Trials are expected to begin in the fall of 2018 with the selection of a handful of Bellwether test cases that will set the tone for future trials or settlement negotiations.

Those affected may still file a claim to join the Invokana Class Action Lawsuit MDL. However, time is limited. Contact us today to speak with a lawyer at no cost about your options.

In addition, reports have linked the drug to blood clots, stroke, pancreatitis, infection and hair loss.

Overall, the FDA has received more than 6,000 reports of serious side effects among patients. In many cases, these were complications that were not disclosed by the manufacturer.

The first case against Invokana was filed in 2015 and the litigation has now grown to more than 1,000 cases in federal MDL courts. Invokana lawyers are still helping those affected file claims. Contact us today to learn more.

Updates by Year

As the growing Invokana litigation enters its third year in 2018, experts believe the thousands of injured patients could finally see a resolution of their case.

The number of claims filed in the federal MDL court has eclipsed 1,000, and this doesn’t account for hundreds of other cases filed in state courts or being prepared for filing.

In the Invokana MDL 2750, Case Management Conferences have been scheduled every month to prepare for the first round of trials, which are set to begin in September.

With the pressure of highly-publicized trials, J&J could agree to settle (link to settlement page) many of the outstanding Invokana Lawsuits in 2018.

For now, there is still time left to file a claim. If you have questions about your Invokana injuries, or wish to speak with a lawyer, contact us today.


As Invokana lawsuits entered 2017, word began to spread of the drug’s risks and the opportunity for those injured to seek justice due to the creation of the federal MDL court.

As a result of the added publicity, more patients that had experienced severe side effects without knowing the reason learned of the connection with their diabetes medication.

The number of lawsuits grew substantially to more than 900 by the end of 2017, with claims added for stroke, blood clots, pancreatitis and other side effects.

Also, the EMA and FDA added formal boxed warnings to Invokana for increased amputation risks, after CANVAS study data showed patients could double their risks by taking the drug.

As litigation continued to grow, rumors emerged that Johnson & Johnson had begun trying to settle some of the cases before they reached a public trial.


2016 was an important year in the development of Invokana litigation. Beginning in January, the Institute for Safe Medication Practices reported on a troubling increase in the number of adverse event reports filed for Invokana with the FDA.

The FDA, having already warned patients of ketoacidosis risks, adds stronger warniings to Invokana for kidney damage, and also reports on new studies showing the drug may increase the risk of leg amputations.

Finally, that December, with more than 140 lawsuits already filed in courts around the country, the federal Judicial Panel on Multidistrict Litigation joins the cases into one centralized court for easier handling.

It's important to speak with a lawyer if you or a loved one suffered amputation, ketoacidosis or kidney injury after taking Invokana. However, choosing the right one can have a significant impact on your case. 

First, drug injury lawsuits are often consolidated to special nationwide MDL courts along with thousands of similar cases. Therefore, the lawyer with the experience and specialization for your case may not be located in your city or even your state.

However, your lawyer will come meet you in person if necessary, then handle all aspects of your case for you. Therefore, it is likely you won’t have to leave your home.

Your Invokana lawyer should also have a detailed understanding of clinical trials and side effect research, as well as access to the experts that perform these reviews.

Finally, your lawyer must have the experience of fighting claims against large and formidable opponents like multinational drug companies, as well as the resources to complete your case.
