Risks and Side Effects of Diabetes Drug Invokana

Potential Increased Risk of Amputations

May 18, 2016: Food and Drug Administration (FDA) releases  a Drug Safety Announcement  for patients taking Invokana, as an ongoing clinical trial found a potential increase in leg,  foot, and toe amputations. The FDA is currently investigating the link between Invokana and amputations, and has plans to update consumers as they receive more information.

PA Lawyers for Invokana Side Effects Lawsuit

Possible Side Effects of INVOKANA®

INVOKANA® may cause serious side effects, including: kidney problems, a high amount of potassium in your blood (hyperkalemia), or low blood sugar (hypoglycemia). If you take INVOKANA® with another medicine that can cause low blood sugar, such as a sulfonylurea or insulin, your risk of getting low blood sugar is higher. The dose of your sulfonylurea medicine or insulin may need to be lowered while you take INVOKANA®.

Signs and symptoms of low blood sugar may include: headache, drowsiness, weakness, dizziness, confusion, irritability, hunger, fast heartbeat, sweating, shaking, or feeling jittery.

It is advisable to visit that website’s full disclosure about possible serious side effects of being prescribed Invokana.

Reports of Kidney Failure & Other Urinary Problems

Invokana and other SGLT2 inhibitors force the kidneys to process excess glucose, which may be why so many kidney problems have been reported by people prescribed Invokana. The Institute for Safe Medication Practices (ISMP) released a report in May, 2015 warning about adverse reactions being reported by patients prescribed Invokana. Among the reported symptoms, several involve kidney-related problems, including over 50 people suffering from kidney failure. Over 10 people developed kidney stones, 50 people in the study developed urinary tract infections.

Prior to approval by the FDA, clinical trials were conducted in 2013. Patients experienced increased onset of fungal infections, and studies in animals indicated that long-term use of the drug could lead to kidney damage, cancers, and bone abnormalities. Janssen, the manufacturer of Invokana, has strong warnings to avoid the medication if you have existing kidney problems or are on dialysis.

Heart Attacks Reported By Those Prescribed Invokana

Myocardial infarction is the clinical term for a heart attack, and involves the blood flow being cut off from the heart, which in turn stops the flow of oxygen to the heart and causes damage to the heart muscle. The most commonly reported symptoms are pain and tightening in the chest. Discomfort can be felt in the left shoulder, arm, or back. Most heart attacks are caused by heart disease resulting from smoking, diabetes, poor diet, or a family history of heart disease.

Early reports from an ongoing comprehensive study of the side effects of Invokana have suggested a much higher incident rate of heart attacks among Invokana users.

What is Ketoacidosis?

Ketoacidosis is a medical condition whereby the body isn’t receiving enough glucose (blood sugar), so it begins burning fat for energy.  The fat is broken down into acids.  These acids appear in the blood and urine as ketones.  As the ketones build up in the blood they can begin to poison the body.  If left untreated, ketoacidosis can lead to coma or death. Diabetic ketoacidosis (DKA) is serious and can be fatal.

Signs & Symptoms of Ketoacidosis

Because ketoacidosis is rare in Type 2 diabetics, it is important that any Type 2 diabetic that has been prescribed Invokana be familiar the signs and symptoms. DKA is your body’s way of letting you know that your blood sugar is out of control.

Initial Symptoms of DKA

  • Increased thirst or dry mouth
  • Frequent urination
  • High blood sugar (glucose)
  • Ketones in urine (evident with the use of a test strip)


More advanced symptoms of DKA

  • Exhaustion – constantly tired
  • Dry skin, flushed appearance
  • Nausea & vomiting
  • Abdominal pain
  • Difficulty breathing
  • Sweet-smelling (almost fruity) breath
  • Inability to concentrate


Harmful Side Effects Leading to Drug Recalls and FDA Warnings

Medications are the subject of a drug recall all the time, primarily because of reports of adverse interactions or drug side effects. Unfortunately, even some doctors are not aware of the long term side effects of the drugs they prescribe. As reports surface, a drug may be voluntarily recalled by the manufacturer, or as in the case of Invokana, the FDA may issue a warning. Warnings from the FDA often become official recall notices. If you or a loved one has suffered harmful side effects as the result of being prescribed Invokana or any other harmful drug, you have the right to hold the manufacturer of that drug responsible for your injuries.
