Diabetes medications are meant to help people manage their health, not put them in danger. But over the last several years, growing concerns have surfaced around the safety of Invokana a medication for type 2 diabetes that has been connected to serious medical risks like bone fractures, diabetic ketoacidosis, and even amputations. Many patients in Tulsa and across the country are now seeking legal help to hold the manufacturer accountable.
If you or someone you love experienced serious side effects after taking Invokana, this guide explains the medical risks, FDA warnings, and legal options available. Graves McLain Injury Lawyers is committed to helping Oklahoma residents navigate defective drug claims with confidence and care.
Invokana, also known by its generic name canagliflozin, is a prescription drug used to treat Type 2 diabetes. It belongs to a group of medications called SGLT2 inhibitors, which work by helping the kidneys remove excess glucose through urine. The drug was approved by the U.S. Food and Drug Administration (FDA) in 2013 and has since been widely prescribed across the United States.
Unfortunately, shortly after its release, patients began reporting severe side effects not clearly explained in the drug’s warning label. These complications included diabetic ketoacidosis, a serious condition that can lead to hospitalization, as well as sudden bone fractures and loss of bone density.
Janssen Pharmaceuticals, a division of Johnson & Johnson, manufactures Invokana. Lawsuits filed across the country claim that the company failed to warn patients and doctors about the drug’s dangers adequately.
Since its initial approval, the FDA has issued several warnings about Invokana. These warnings are based on post-market studies and adverse event reports that show a clear link between the drug and certain health complications.
In 2015, the U.S. Food and Drug Administration issued a warning that Invokana could cause serious side effects, including diabetic ketoacidosis, bone fractures, and a reduction in bone mineral density. (FDA Drug Safety Communication, 2015 & 2017)
In May 2015, the FDA alerted the public about the risk of ketoacidosis, a potentially life-threatening condition in which the blood becomes acidic. Symptoms can include nausea, vomiting, stomach pain, shortness of breath, and confusion. Later that year, in September, the agency added a new warning about decreased bone density and the risk of fractures—especially in the hips and lower spine.
Post-menopausal women and older adults appear to face a higher risk of bone density loss when using SGLT2 inhibitors like Invokana.
In 2017, the FDA added its most serious warning—a black box label—citing an increased risk of lower limb amputations, particularly affecting the toes and feet. These complications can begin within just 12 weeks of treatment.
Thousands of lawsuits have been filed against Janssen Pharmaceuticals for injuries related to Invokana. Many of these were consolidated into multidistrict litigation (MDL 2750) to streamline the process in federal court.
Multidistrict litigation (MDL 2750) was established to consolidate Invokana lawsuits in federal court, allowing plaintiffs to share discovery and streamline proceedings.
These lawsuits typically claim:

Invokana is a prescription drug used to treat Type 2 diabetes. Lawsuits allege that it causes severe side effects like ketoacidosis, bone fractures, and even amputations, which were not adequately disclosed to patients.

Oklahoma has a two-year statute of limitations for most personal injury claims. If your injury occurred recently, or you only just discovered the link to Invokana, you may still have time.
Many cases were part of a federal multidistrict litigation (MDL), but some were filed individually. Your case type depends on the details and timing of your injury.
Compensation may include medical expenses, lost wages, and pain and suffering. However, the amount depends on the severity of the injuries and case-specific evidence.
