Should I Talk to a Lawyer About the Experience I had With the Drug Invokana?

If you or a loved one used the type 2 diabetes medication Invokana, you might be eligible for financial compensation. Some Invokana users have required amputation of the leg, foot or toe after using the drug. Others have developed diabetic ketoacidosis or suffered other side effects such as severe kidney infection, heart attack or stroke after taking Invokana.

Invokana (canagliflozin) is an SGLT2 inhibitor, which is a type of medication that works by lowering blood glucose levels. It does this by encouraging higher amounts of sugar to be released through urine. Though the medication does help control blood sugar levels, it triggers a number of other side effects, many of which are severe.

Some Invokana users experienced cardiovascular issues including heart attacks and strokes, as well as diabetic ketoacidosis and kidney health issues. Final results from two clinical studies, CANVAS and CANVAS-R have shown that use of Invokana may double the risk for limb amputation and have prompted the FDA to release a black box warning about the risk.

For some, the use of Invokana triggered side effects so severe they needed hospitalization. Others suffered permanent disability.

In response to these devastating medical emergencies, many Invokana users have opted to take legal action against the makers of the drug. Both Janssen Pharmaceuticals and its parent company, Johnson & Johnson, allegedly failed to warn consumers and doctors about the risks linked to their drug.

Side Effects of Invokana

A number of serious adverse events have been linked to Invokana. These severe side effects include:

  • Kidney injury and kidney failure
  • Urinary tract infection
  • Cardiovascular problems including heart attack and stroke
  • Diabetic ketoacidosis
  • Amputation of the leg, foot or toe

Diabetics face an increased risk for vascular problems, which in some cases can lead to the need for amputation. Final results from two separate clinical trials have shown that diabetics treating their disease with Invokana may have a risk of amputation that is twice as high as expected.

In addition to requiring labeling changes, the black box warning issued on May, 16, 2017 advises patients that any symptoms of inflammation, pain or tenderness, sores or ulcers or signs of infection that develop in the legs or feet should be reported to a health care practitioner.

It also recommends that health care practitioners consider other patient risk factors such as peripheral vascular disease, neuropathy or prior amputation history before prescribing Invokana. Health care practitioners are advised to monitor patients and discontinue Invokana if new signs or symptoms develop.

If you experience any unusual symptoms in your extremities, or you have any symptoms that could be related to heart or kidney health issues, you should seek medical attention immediately.

Do You Have an Invokana Lawsuit?

Medical injuries caused by Invokana have required hospitalization, surgery, and extensive medical treatments. In some cases, injuries have been permanent, resulted in disability or even death.

Invokana users and their families may have a right to take legal action against Janssen and Johnson & Johnson if their use of the drug caused serious injuries. Current Invokana lawsuits allege the companies were aware of the risks and failed to warn doctors and consumers. Users of the drug claim if they had known of the risks they would have opted for a different course of treatment.

Those who were injured or lost loved ones after use of Invokana to treat type 2 diabetes could be eligible for financial compensation for medical treatment, lost wages, and pain and suffering. If it can be proven the drug makers were aware of the risks, those affected might also be entitled to punitive damages.

Several lawsuits regarding Invokana have already been filed in courts across the country. If enough Invokana users take action, these cases might be combined into multi-district litigation, making the process of resolving the matter easier for everyone involved.

With the FDA’s most recent, black box warning about Invokana, it is expected additional lawsuits will be filed.
