South Carolina Invokana and Invokamet Injury Lawsuits

Attorneys helping clients who were prescribed a dangerous drug for their type 2 diabetes

**McGowan, Hood & Felder, LLC is no longer accepting cases involving Invokana or Invokamet**

Millions of people suffer from type 2 diabetes, a serious and sometimes debilitating medical condition that requires specific medication to control. You trust that the medicine your doctor prescribes will make you better, not worse. However, Invokana and Invokamet have caused serious injuries, including heart problems and an increased risk of amputations for some users.

When your prescription drug causes dangerous side effects, you have the right to pursue justice. If you or a loved one has been harmed by Invokana or Invokamet, turn to an experienced attorney at McGowan, Hood & Felder. Our South Carolina drug liability lawyers know how to get you the compensation you need and deserve.

What are the dangerous side effects of Invokana and Invokamet?

Invokana, or canagliflozin, is a drug used to treat type 2 diabetes by helping your kidneys eliminate glucose from your bloodstream and lowering blood sugar levels. Invokamet is a combination of Invokana and metformin.

There are many possible side effects of both drugs, including:

  • Diabetic ketoacidosis
  • Fournier’s Gangrene
  • Lactic acidosis
  • Heart attack
  • Stroke
  • Kidney failure


  • Kidney stones
  • Urinary tract infections
  • Bladder cancer
  • Increased risk of amputation
  • Coma
  • Death


FDA safety warnings about adverse effects from Invokana

The FDA issues drug safety communications to consumers and medical professionals after it has received adverse event reports from consumers and medical professionals. The following are a few drug safety communications about Invokana from the FDA:

  • In August 2018, the FDA issued a safety warning about rare occurrences of a serious infection of the genital area in those who are taking SGLT2 inhibitors like canagliflozin. This serious, rare infection is called necrotizing fasciitis of the perineum, also called Fournier’s gangrene. The FDA required a new warning about this risk be added to prescribing information for all SGLT2 inhibitors.
  • In May 2017, the FDA issued a safety communication about the increased risk of leg and foot amputation in patients who take Invokana, Invokamet, and Invokamet XR. Data from two large clinical trials revealed that canagliflozin causes an increased risk of leg and foot amputations. The FDA required new warnings, including a black box warning, to be added to the drug labels describing this risk.
  • In June 2016, the FDA issued a safety communication that strengthened its warning about the risk of acute kidney injury, and the drug labels have been revised to include information about acute kidney injury and recommendations on how to minimize this risk.

What you must prove in your defective drug injury lawsuit

In order to be successful in your defective drug lawsuit in South Carolina, you must be able to prove the following:

  • The drug was either defective or improperly marketed
  • You were injured or harmed by using the drug
  • The drug’s defect or improper marketing was the cause of your injury

Often, just suffering from dangerous side effects is not enough proof for a claim if you were adequately warned of the side effects before taking the drug. However, because the most dangerous side effects of Invokana and Invokamet, such as ketoacidosis and amputation, were not discovered until after the drug was already administered, you can file a potentially successful lawsuit.

Lawsuits for Invokana injuries

If a pharmaceutical company includes a warning about a known side effect from taking its medication, a person who suffers the side effect they were warned about does not have grounds for an injury lawsuit. However, if a person is injured from side effects that the drug maker did not warn consumers about, the drug maker may be held liable for the injuries.

Lawsuits have been filed by people throughout the U.S. who have suffered injuries such as kidney failure, ketoacidosis, or a lower limb amputation after taking Invokana and other SGLT2 inhibitors to manage type 2 diabetes.

A defective drug attorney at our firm will assist you in gathering the evidence you need to file a claim.

Do I have to hire a lawyer for my defective drug injury case?

If you have sustained a serious injury after taking a dangerous drug like Invokana, and you want to pursue compensation for your losses, you only get one chance at a claim. If you are unfamiliar with what is required to win your claim, you might benefit from working with an experienced medical product liability lawyer. We investigate your claim, gather evidence, work with expert witnesses, and develop a winning strategy for litigating your case.

Can I afford a lawyer?

Yes, you can. Our attorneys work on contingency fee basis, which means that you pay nothing unless we successfully resolve your case. Even the initial consultation is free.

What damages are available for a drug injury case?

If you have been seriously injured because of a prescription drug, our civil justice system provides a remedy in the form of financial compensation. Drug manufacturers owe a duty of care to the consumers of their products to produce medicines that are safe and effective at doing what they were designed to do. When you file an injury claim against a pharmaceutical company for the adverse effects of its drugs, the damages in a successful lawsuit might include:

  • Medical expenses
  • Pain and suffering
  • Lost wages
  • Emotional distress
  • Wrongful death (if the injury results in death)
  • Punitive damages (where appropriate)

How much is my injury case worth?

Not surprisingly, this is one of the most common questions we hear from new clients; however, it is not a question we can answer with any accuracy at the start of a new case. There are so many variables when it comes to a defective drug injury case. One of the major factors is the severity of the injury and the degree of residual disability if the injury has resolved.

While we cannot tell you exactly how much your injury case is worth, we can tell you that we have a strong record of obtaining solid settlements and verdicts on behalf of our clients. Our dangerous drug injury attorneys are prepared to do everything we can to make sure you win.
