Invokana is a new class of Type 2 diabetes drug called sodium-glucose co-transporter 2 (SGLT2). This class of Type 2 diabetes drugs work by stopping glucose from being reabsorbed into the blood. The FDA approved Invokana in 2013. In May 2015 the FDA release a statement warning doctors and patients that SGLT2 drugs may lead to DKA. If DKA is left untreated, it can be fatal.
In December 2015, the FDA ordered manufacturers of SGLT2 inhibitors to add warnings regarding the risk of urinary tract infection and ketoacidosis to the drugs’ labels.
Diabetic ketoacidosis occurs when the body does not have enough insulin to manage glucose levels. During diabetic ketoacidosis the body starts developing a waste product known as acidic ketone bodies by burning fatty acids. Ketones are what cause symptoms of ketoacidosis. These symptoms include abdominal pain, fatigue, confusion, vomiting, and dehydration. In some rare cases, ketoacidosis can cause coma or death.
