Has the FDA Taken any Action Against the Makers of Invokana?
On May 29, 2013, the FDA (Food and Drug Administration) approved the use of Invokana to treat patients who have type II diabetes. When Janssen Pharmaceuticals, a subsidiary of Johnson & Johnson, submitted a new application to the FDA the approval process took less than a year for the federal agency to consent to its sale in the U.S. medical marketplace. Since then, there have been many actions taken by the FDA against the maker of the selective sodium glucose co-transporter 2 (SGLT2) inhibitor medication Invokana.

The Drug has not Been Recalled
To date, the FDA has not issued a formal recall of Invokana or any other SGLT2 inhibitor medication because of serious problems and dangerous side effects. However, this should not come as any surprise. The FDA moves very slowly and is extraordinarily cautious in issuing a recall of any pharmaceutical product and usually do not take action until there is significant push back from doctors, injured patients or the medical community. The federal agency normally takes many years to conduct exhaustive investigations before reaching any decision to recall.
However, the government agency has issued a warning for drugs containing canagliflozin (the active ingredient in Invokana), dapagliflozin, and empagliflozin as well as SGLT2 inhibitors in general. The FDA says that these medications might lead to "A serious condition where the body produces high levels of blood acids called ketones that may require hospitalization." The FDA advised patients through an issued warning to look for the following symptoms and tell their doctor if they appear:
- Difficulty breathing
- Abdominal pain
- Unusual fatigue or sleepiness
Of course, the FDA has urged patients to continue taking their medication until they have spoken with a doctor but alerted consumers to any side effects in the following SGLT2 inhibitors:
- BRAND NAME
- XIGDUO XR
- ACTIVE INGREDIENT(S)
- CANAGLIFLOZIN AND METFORMIN
- DAPAGLIFLOZIN AND METFORMIN EXTENDED-RELEASE
- EMPAGLIFLOZIN AND LINAGLIPTIN
Stronger Canagliflozin Warnings
In 2016, the FDA updated a previously released Safety Alert by calling attention to the potentially serious risks of amputation affecting patients taking Invokana, Invokamet and other canagliflozin medications. The federal agency ordered the pharmaceutical manufacturer to carry stronger warnings on the drug's Black Box Warning Label that details its severe, life-threatening risks. In May of that year, the drug maker publicized the results of a clinical trial that revealed the incident rate of amputations was significantly higher among individuals who took the drug compared to others taking a placebo.
The Safety Alert warned patients that they were twice as likely to undergo a limb or appendage amputation. A second clinical trial verified the elevated risk of amputation involving Invokana use.
An FDA spokesman released a statement over their concerns saying “Based on new data from two large clinical trials, the FDA has concluded that the type II diabetes medicine canagliflozin [including Invokana, Invokamet, and Invokamet XR] causes an increased risk of leg and foot amputations. The FDA requires new warnings, including the most prominent Box Warning, to be added to the canagliflozin drug labels to describe this risk.”
A Drug Defect?
Doctors prescribe Invokana, Invokamet, and other canagliflozin medicines to lower blood sugar levels in patients with type II diabetes. However, to be highly effective, the medication should be used alongside routine exercise and a healthy diet. The drug is an SGLT2 inhibitor that helps the kidneys remove sugar (glucose) from the body through urination. Invokana is a single drug and Invokamet is a combination drug that is formulated with Metformin.
The results of clinical trials revealed that Invokana could reduce A1c levels (a measure of glycated hemoglobin in the bloodstream) to below 7.0%. Doctors diagnose type II diabetes in patients with an A1c level of 6.5% or higher. Patients with an A1c level between 5.7% and 6.4% are usually diagnosed with a prediabetic condition.
A Janssen Pharmaceuticals spokesperson stated that it was the clinical trials that prompted the FDA to call for a stronger warning labeling, even though the greatest risk for amputation was found in patients who had already undergone an amputation procedure. The pharmaceutical giant released the results of their clinical trials at the annual meeting of the American Diabetes Association in June 2017.
The data revealed how Invokana reduced the incident rate of stroke, heart attacks, and cardiovascular death among diabetic patients at the highest risk. However, the company did state that taking the popular diabetes medication doubled the patient's risks of needing a lower extremity amputation when compared to other SGLT2 inhibitor medications like Jardiance.
Severe Health Complications
The new additions to Invokana's Black Box Warning Label only added to the already known serious side effects the product can produce, including death. Many of the side effects caused patients to be hospitalized or receive treatment in the emergency room or intensive care unit. In addition to amputations, other known Invokana side effects involve:
- Diabetic Ketoacidosis – The FDA ordered Invokana makers to add ketoacidosis and urinary tract infections to its Black box warning label. This condition occurs when the body produces excessive amounts of ketones and chemicals that accumulate in the bloodstream. When dangerously elevated levels are reached, the outcome can be deadly.
- Kidney Injury – The federal agency issued a Safety Communication release that warned patients that taking SGLT2 inhibitor medications for the treatment of type II diabetes could increase the risk of kidney injuries including kidney failure. The safety warning involved taking Invokana, Invokamet, Farxiga and Xigduo XR. Between 2013 in 2015, the FDA received more than 100 reports of patients who suffered acute kidney injury. Seventy-three of the patients had taken Invokana, and 28 others took Farxiga.
- Acute Pancreatitis – The FDA linked the use of SGLT2 inhibitor medications, including Invokana, to acute pancreatitis. A spokesperson stated in the FAERS (FDA Adverse Event Reporting System) that the agency is “evaluating the need for regulatory action” over the potential risk of developing this life-threatening condition.” However, the agency also stated that “the appearance of a drug on this list does not mean the FDA has concluded that the drug has a listed risk. It means that the FDA has identified a potential safety issue, but it does not mean the FDA has identified a causal relationship between the drug and the listed risk.”
- Bone Fracture – A safety warning from the FDA revealed their concerns over the increased potential risk of Invokana users to experience bone fractures. Because of this, the federal agency required an update to the medication's warning label that describes that there is an increased potential risk for reduced bone marrow density.
- Urinary Tract Infections that can cause blood infections (sepsis).
- Cardiovascular Problems including heart failure.
Worldwide Scrutiny Over Invokana use
In the last few years, there has been significant scrutiny worldwide over the use of SGLT2 inhibitors including Invokana and Invokamet. A December 2014 report from Lancet Journal of Diabetes and Endocrinology revealed evidence showing SGLT2 inhibitors had the potential of increasing the risk of bone fractures. The report urged further investigation which likely prompted the additional warnings issued by the FDA.
The European Medicines Agency (EMA) initiated an investigation in June 2015 to verify the potential risks of Invokana users developing diabetic ketoacidosis. The study included more than 100 patients who had developed the life-threatening condition after taking an SGLT2 inhibitor drug. In late April 2018, plaintiffs in Canada filed the first “class action” suit alleging that the Invokana is dangerous and known to cause kidney failure. Oddly, Health Canada, a governmental health regulating agency, had only recently approved the drug for use in May 2014. Many of the lawsuits claimed that Janssen Pharmaceuticals failed to warn patients and doctors that their product had severe side effects and the company was negligent for their failure to test the drug properly.
A Supplemental New Drug Application
In October 2017, the research and development department of Janssen Pharmaceuticals submitted a supplemental New Drug Application to the FDA. The company is seeking to expand approved use for Invokana, Invokamet and Invokamet XR to reduce the potential risk of Major Adverse Cardiovascular Events (MACE). The drug manufacturer wants the approval for doctors to prescribe their medications to reduce the risk of stroke, myocardial infarction, and cardiovascular (CV) death.
The expansion of their medication to reduce cardiovascular problems is the result of the findings revealed after their clinical trial program was completed. The program helps to clarify the canagliflozin drug's cardiovascular safety and efficacy in patients taking Invokana compared to those taking a placebo.
Have I Been Injured by Invokana?
The new safety communication warnings issued by the FDA calls into question the health of every individual taking Invokana or Invokamet. However, the Food and Drug Administration has not yet recalled the drug or pulled it from the medical marketplace completely. The clinical trials have revealed that only about eight individuals out of every 1000 patients taking the prescription drug have an increased risk of amputation.
Even so, every patient taking Invokana should remain cautious and look for obvious indicators of harm when taking the drug. These indicators could include:
- Hypersensitivity reaction including swelling, hives, itching, and skin rash or redness
- Yeast infection
- Genital itching
- Candida infection
- Urinary tract infections
- Unconscionable thirst
- Dry mouth
- High cholesterol
- Increased urination
- Light Sensitivity
- Kidney problems including acute renal failure
- Reduced kidney function
- Diabetic ketoacidosis
- Bloodstream infection (sepsis)
- Decreased bone density (decalcification)
- Bone fracture
- Dizziness or fainting
- Abnormally low blood pressure
- Extreme water loss
- Elevated magnesium or potassium levels in the bloodstream
- Elevated phosphate levels in the bloodstream
- Elevated levels of hemoglobin
