Invokana Complications: Foot and Leg Amputation

Commonly asked questions about Invokana and its link to foot and leg amputation:

Can Invokana Cause You To Have To Get Your Foot or Leg Amputated?

The U.S. Food and Drug Administration recently issued a safety alert that the diabetes drug canagliflozin (Invokana) has been associated with an increase in leg and foot amputations — largely affecting the toes.

The FDA is reportedly investigating the safety issue, but has yet to determine if taking canagliflozin (Invokana) is associated with an increased risk of leg and foot amputations.

The safety alert was issued nearly two weeks after the European Medicines Agency (EMA) announced that it was conducting an investigation into reports of lower limb amputations.

The FDA and EMA both approved Invokana in 2013 as a treatment for type 2 diabetes.

Does Invokana Increase The Risk of Having To Get A Foot or Leg Amputated?

The FDA’s safety communication comes after a four-year interim analysis, completed by the independent monitoring committee for the Canagliflozin Cardiovascular Assessment Study (CANVAS).

The study tracked roughly 4,000 type 2 diabetes patients treated with either a 100 mg or 300 mg daily dose of Invokana or a placebo. The panel reportedly found there were higher rates of lower-limb amputation in the Invokana groups.

On May 16, 2017, the FDA put out a safety announcement confirming an increased risk of leg and foot amputations with the SGLT2 inhibitor canagliflozin (Invokana, Invokamet).

“Based on new data from two large clinical trials, the U.S. Food and Drug Administration (FDA) has concluded that the type 2 diabetes medicine canagliflozin (Invokana, Invokamet, Invokamet XR) causes an increased risk of leg and foot amputations. We are requiring new warnings, including our most prominent Boxed Warning, to be added to the canagliflozin drug labels to describe this risk,” the warning says.

“Patients taking canagliflozin should notify your health care professionals right away if you develop new pain or tenderness, sores or ulcers, or infections in your legs or feet. Talk to your health care professional if you have questions or concerns. Do not stop taking your diabetes medicine without first talking to your health care professional.”

What Kind of Foot Complications Can I Develop?

People with diabetes can develop many different foot problems.

Foot problems most often happen when there is nerve damage, also called neuropathy. Neuropathy can cause tingling, pain (burning or stinging), or weakness in the foot, according to the American Diabetes Association.

Below is a list of a half-dozen foot complications often caused by type 2 diabetes.

  1. Neuropathy
  2. Skin changes
  3. Calluses
  4. Foot ulcers
  5. Poor circulation
  6. Amputation

What Can I Do to Reduce Foot and Leg Complications?

According to the Mayo Clinic, the best strategy for preventing complications of diabetes is proper diabetes management with a healthy diet, regular exercise, blood sugar monitoring and adherence to a prescribed medication regimen.

Proper foot care will help prevent problems with feet and ensure prompt medical care when problems occur. The following is a list of 10 tips for preventing foot complications due to diabetes, according to the Mayo Clinic:

  1. Inspect your feet daily

  5. Don’t go barefoot

What are the Criteria for Filing an Invokana Lawsuit?

Approved in March 2013, Invokana (canagliflozin) is an SGLT2 Inhibitor used to treat adults with Type 2 diabetes, manufactured by Janssen Pharmaceuticals, a subsidiary of Johnson & Johnson.

SGLT2 inhibitors work by preventing high blood sugar by helping the patient’s kidneys remove excess sugar through their urine.

In May 2015, the U.S. Food and Drug Administration (FDA) issued a warning the drug has been linked to cases of ketoacidosis, a serious condition where there is too much acid in the blood.

Complications of diabetic ketoacidosis include difficulty breathing, nausea/vomiting, abdominal pain, confusion and unusual fatigue or sleepiness. The condition can lead to diabetic coma and/or death.

The national Invokana lawsuit alleges that the manufacturers and marketers of SGLT2 Inhibitors failed to warn patients and physicians of the increased risks of kidney failure, myocardial infarction (heart attacks), other cardiovascular issues, and ketoacidosis.

The lawsuit states that if the manufacturers and marketers had properly warned of the risks, patients would have been prescribed and taken a substitute medication for their diabetes and would have had their health monitored on a more routine basis for potential signs of heart issues, renal impairment, and high level of ketones.

If you suffered severe complications from taking an SGLT2 Inhibitor, you may be entitled to compensation. Below is the criteria required to file an SGLT2 Inhibitor lawsuit:

  • Patient has taken Invokana, Invokamet, Farxiga, Glyxambi, Jardiance, or Xigduo XR and suffered one or more of the following:
