Invokana Lawsuit  

Some patients with Type II Diabetes struggle to lower their blood sugar, or A1C, even with changes in diet and exercise. For these patients, a class of medications called sodium-glucose cotransporter-2 (SGLT2) inhibitors may be helpful. However, many patients have reported adverse effects, some serious, from certain SGLT2 inhibitors, including Invokana.

What is Invokana?

Invokana is Prescription medication for Type II Diabetes produced by Janssen Pharmaceuticals, a division of Johnson & Johnson. This drug is intended to reduce A1C numbers by affecting how the kidneys process glucose. It is not designed for Type I Diabetes or individuals with a history of diabetic ketoacidosis (increased ketones). It’s also never been shown to be safe or effective for kids younger than 18.

Fournier’s Gangrene and Invokana

Invokana, which is in the SGLT2 drug class, has been found to cause gangrene of the genitals, a flesh-eating genital infection also known as necrotizing fasciitis or Fournier’s gangrene. Additionally, the FDA warned in 2018 that Invokana, Invokamet, Farxiga, and Jardiance can lead to an increased risk of amputations. At one point, they required a boxed warning for these medications (a warning included in the drug packaging) noting the risk of amputation, but in 2020, they removed that requirement. Their statement noted that the risk of amputation was still higher with SGLT2 inhibitors than without them and that healthcare providers should consider the risk factors for amputation before prescribing diabetes medication.

Symptoms of Fournier’s Gangrene

It’s important to recognize the potential signs of this serious condition, because you may need treatment, including antibiotics and even surgery. The sooner you get treatment, the better, so if you have any of these symptoms, please seek medical attention immediately.

  • Fever
  • Pain and swelling around the genitals or anus
  • An unusual odor from the irritated skin tissue
  • The skin of the affected area makes a crackling sound when touched
  • Dehydration
  • Anemia

Invokana Linked to Kidney Failure

Unfortunately, necrotizing fasciitis isn’t the only risk with Invokana and other drugs in its class. Invokana was approved for use in 2013, and by 2015, the FDA had received over 100 reports of acute kidney injury in patients using the drug. (There were likely more cases that went unreported.) In 2016, the FDA expanded warnings about the potential for kidney damage and included recommendations for reducing the risk of kidney injury when taking Invokana.

Signs of Acute Kidney Injury

According to the FDA, the two main symptoms of acute kidney injury to look out for are decreased urination or swelling of the legs and feet. If you notice these, you should contact your doctor immediately. Don’t stop taking Invokana before speaking with your healthcare provider, as this could cause sudden changes in your blood sugar.

Ketoacidosis

The American Diabetes Association describes ketoacidosis – also known as acidosis or diabetic ketoacidosis (DKA) – as dangerous levels of blood acids, or ketones, which can cause diabetic coma and may even be fatal. This condition often occurs in Type I Diabetes but is relatively rare in Type II Diabetes. Because Invokana works in the kidneys, causing glucose to be reabsorbed into the blood, it may cause ketones to rise as the body breaks down fat for energy. After reports of about 20 cases of this serious condition from patients using SGLT2 inhibitors, the FDA began a review of this drug class.

Diabetic Ketoacidosis (DKA) is a known side effect of many diabetes medications. But one study found that SGLT2 inhibitors carry about three times the risk of DKA than a different class of drugs called DPP-4 inhibitors. Invokana was also associated with a higher risk of DKA than two other drugs in the class, Jardiance, and Farxiga.

Unfortunately, ketoacidosis can sometimes cause severe organ damage, and the treatment options for this condition can also lead to side effects like brain swelling, low blood sugar, and low blood potassium. If you suffered serious injury from ketoacidosis while taking Invokana, you may deserve compensation.

Symptoms of Ketoacidosis

Early symptoms of DKA include an increase in thirst and urination. If left untreated, DKA can progress to more serious symptoms, including:

  • Rapid, deep breathing
  • Dry skin and mouth
  • Facial flushing
  • Fruity-smelling breath
  • Headache
  • Muscle aches or stiffness
  • Fatigue
  • Nausea and vomiting
  • Abdominal pain

If you experience these symptoms, please call your healthcare provider right away.

Legal Precedents for Invokana Lawsuits

There are several grounds for dangerous drug lawsuits. Depending on your specific situation, your Invokana lawsuit lawyer may file a lawsuit for one or more of the following reasons:

Drug Proved to Be Unreasonably Dangerous

Product manufacturers, including pharmaceutical companies, have a duty to ensure their products are safe for consumer use. Of course, all medications have risks, but in some cases, the risks are not known until many patients have suffered complications. If the drug turns out to be unreasonably dangerous, the manufacturer could be liable.

Missouri’s strict liability law states that the defendant in product liability claims, such as dangerous drug cases, is liable under the following circumstances:

  • The defendant (usually the manufacturer in dangerous drug cases) transferred the product in the course of business – in other words, they sold the defective product.
  • The plaintiff (the person filing the lawsuit) used the product in a way that the manufacturer or seller should have reasonably expected.
  • The product proved to be unreasonably dangerous. It was either in this defective and unreasonably dangerous condition when it was sold, or it became dangerous when put to a reasonably expected use by the end user.

Many cases revolve around whether or not a drug is unreasonably dangerous. Your lawyer will work to gather evidence that the risks and dangers of the medication were unreasonable for the circumstances.

Failure to Warn

Some dangerous drug lawsuits are based on the product manufacturer’s failure to properly explain the risks and potential side effects of a medication, especially if there is evidence that the company was aware of the risks. The manufacturer is expected to let potential users know the risks of a medication, including adverse effects, even if these are rare. Companies also have a duty to warn consumers if a drug might be dangerous in specific situations, such as when used with certain other medications, or if the patient has another underlying health condition.

In the case of Invokana, there are multiple reports that the manufacturer, Johnson & Johnson, received notice of unexplained ketoacidosis occurring in patients on Invokana as early as 2013. One former company executive told Reuters that key decision-makers ignored his recommendations to include stronger warning for patients and healthcare providers. The FDA later made this decision for Invokana, but by then many patients had suffered severe and sometimes life-threatening complications from ketoacidosis.

Medical Malpractice

In a smaller number of cases, the risks are known, but the patient’s physician prescribed a medication that was not safe based on their medical history. For example, if you had a history of non-healing foot wounds due to your diabetes, and your doctor prescribed Invokana over other drugs without considering the higher risk of amputation, then the physician may be liable for medical malpractice.

Statute of Limitations on Dangerous Drug Cases in Missouri

Missouri law only gives you two years from the date of discovery to file a lawsuit in a dangerous drug case. The “date of discovery” is the date you were diagnosed with complications that may have been caused by your medication. Not all patients are aware that their complications were caused by a dangerous drug – in many cases, their doctor may not have offered any explanation for what happened. For many people, this may mean they don’t have much time left to file their case. If you suffered serious complications while taking Invokana, even if you’re not sure whether they were related to the drug or not, we recommend contacting a dangerous drugs attorney as soon as possible to preserve your legal rights.
