Defective Medical Devices & Dangerous Drugs


Invokana Lawyer

The Food and Drug Administration (“FDA”) approved Invokana in 2013 to treat Type 2 adult diabetes. Injured patients have been filing class action lawsuits claiming that Invokana’s manufacturer, Johnson & Johnson’s pharmaceutical subsidiary Janssen Pharmaceuticals, failed to adequately warn patients and physicians of the dangers of taking Invokana, including an increased risk of limb amputations, heart attack, ketoacidosis, kidney damage, kidney failure, and other serious complications. If you or a loved one have been injured by Invokana, you may be entitled to seek compensation from Johnson & Johnson for your medical bills, lost income, and other losses. Contact Statesman Law Group immediately.

What Is Invokana?

Invokana, which contains the active ingredient canagliflozin, is the first of a class of drugs called sodium-glucose cotransporter-2 (SGLT2) inhibitors to be approved for use in the United States. SGLT2 inhibitors, including Invokana, help regulate blood sugar levels in adult patients with Type 2 diabetes. They accomplish this by forcing the kidneys to remove more sugar from the body through urine. Invokana is not a recommended treatment for Type 1 diabetes.

These kinds of drugs can come with risks, including ketoacidosis, kidney complications, dehydration, higher blood cholesterol levels, and low blood sugar when an SGLT2 inhibitor is combined with another diabetes medication.

What Are the Risks Associated with Invokana?

In 2016, the U.S. Food and Drug Administration (FDA) issued drug safety communications reporting that “interim safety results from an ongoing clinical trial that found an increase in leg and foot amputations, mostly affecting the toes, in patients treated with the diabetes medicine canagliflozin (Invokana, Invokamet)” and “strengthened the existing warning about the risk of acute kidney injury for the Type 2 diabetes medicines canagliflozin (Invokana, Invokamet)…”

In addition to amputation risk and acute kidney injury, Invokana has been linked to the following side effects and complications:

  • Cardiovascular complications
  • Kidney damage or failure
  • Increased bone fracture risk
  • Decreased bone mineral density
  • Low blood pressure
  • Low blood sugar
  • Frequent urination
  • Urinary tract infections
  • Yeast infections
  • Dehydration
  • Faintness
  • High levels of magnesium in blood
  • High levels of potassium in blood
  • Allergic reactions
  • Dry mouth
  • Nausea
  • High levels of cholesterol
  • High levels of hemoglobin
  • Constipation
  • Ketoacidosis 


In May 2017, the FDA announced that it was requiring new warnings, including their most prominent “boxed warning” to be added to Invokana packaging to describe the “increased risk of leg and foot amputations.” The FDA based the new rule on new data from two large clinical trials. Call a medical professional immediately if you use Invokana and experience any odd sensations, soreness, or tenderness in your legs and feet. If you or a loved one have suffered an amputation while taking Invokana, call Statesman Law Group immediately for a free case review.


Ketoacidosis, also known as diabetic ketoacidosis, is a life-threatening complication of diabetes that develops when your body can’t produce enough insulin. If a person doesn’t have enough insulin, their body breaks down fat as a source of energy, which causes the production of toxic acids called ketones. Ketones can accumulate in the blood, posing a danger to the body and potentially requiring hospitalization.

According to the Mayo Clinic, Ketoacidosis develops quickly, and can include:

  • Extreme thirst
  • Frequent urination
  • Nausea
  • Vomiting
  • Dehydration
  • Abdominal pain
  • Fatigue
  • Shortness of breath
  • Breath that smells like fruit
  • Confusion

If you or a loved one has suffered from Invokana related Ketoacidosis, contact Statesman Law Group immediately. We can help you get the compensation you deserve for your injuries.
