Study Links Invokana and Ketone Problems in T1 Diabetes

April 15, 2016 — A study published in Diabetes Care has found that 5-10% of people with type-1 diabetes who take insulin and Invokana developed ketone-related adverse events, including severe ketoacidosis that required hospitalization.

The researchers randomly assigned 351 diabetic people on insulin injections to receive Invokana (100-mg or 300-mg) or a placebo every day before breakfast. After 18 weeks, ketone-related adverse events were significantly more common in patients on Invokana:

  • Any ketone-related adverse event: 5.1% of patients on 100-mg dose and 9.4% on 300-mg dose.
  • Hospitalization for ketoacidosis: 4.3% of patients on 100-mg dose and 6% on 300-mg dose.

Five out of 12 patients who were hospitalized with ketoacidosis had blood-sugar levels below 13.9 mmol/L, which is the standard threshold for diagnosing ketoacidosis. The cases are unusual because ketoacidosis normally occurs along with very high blood-sugar.

The researchers also found that all of the patients who were hospitalized also had other risk-factors for ketoacidosis, including influenza, pneumonia, infusion-site infection, food poisoning, insulin pump failure/malfunction, noncompliance with insulin regimen, or decrease in food intake.

Last year, the FDA revised the label on Invokana to warn about the risk of diabetic ketoacidosis (DKA), a life-threatening condition in which the blood becomes too acidic. Invokana is not approved for people with type-1 diabetes, but it is sometimes prescribed “off-label” to help patients remove more sugar from their body in urine.

Between March 2013 and May 2015, the FDA received 73 reports of ketoacidosis in patients with type-1 or type-2 diabetes on Invokana. The FDA recommends:

“Patients should stop taking their SGLT2 inhibitor and seek medical attention immediately if they have any symptoms of ketoacidosis, a serious condition in which the body produces high levels of blood acids called ketones. Symptoms of ketoacidosis include nausea, vomiting, abdominal pain, tiredness, and trouble breathing.”
