SGLT2 Inhibitors (Invokana, Invokamet, Farixga, Xigduo XR, Jardiance, Glyxambi, Synjardy)
In June 2016, FDA required manufacturers of Invokana®, Invokamet®, Farxiga®, and Xigduo XR® to strengthen warnings on their drug labels to include an association with kidney failure soon after beginning to take the drug. FDA reports that some patients’ kidneys suddenly stopped working within one month of use, among other possible ailments. While many received dialysis after being hospitalized, some cases tragically resulted in death.

What are SGLT2 Inhibitors?

- Invokana® (canagliflozin)
- Invokamet® (canagliflozin and metformin)
- Farxiga® (dapagliflozin)
- Xigduo XR® (dapagliflozin and metformin extended-release)

FDA Warnings Related to Some Diabetes Medicines
In 2015 FDA forced manufacturers to strengthen side effect warnings on Invokana and other SGLT2 inhibitors after linking these drugs to a serious complication called ketoacidosis, also known as diabetic ketoacidosis (DKA) or ketosis. DKA can lead to severe kidney complications, heart attack, stroke or even death.
Ketoacidosis, or an excess of blood acids, occurs when the body is unable to regulate the natural production of ketones and the pH balance of the blood drops significantly. For type 1 diabetics, this is often accompanied by a spike in blood sugar levels. For type 2 diabetics, however, blood sugar levels may only increase slightly and symptoms may not be evident until they become severe.
While Invokana is only approved for use with type 2 diabetics, it has been known to be prescribed to type 1 diabetics as well as being off-label marketed as a weight loss drug.
