If you took Invokana and had a Toe, Foot, Leg Amputation or Diagnosed with Ketoacidosis, You May Have a Claim Against the Drug Maker

Invokana is a new class of diabetes medicine promoted as being able to lower blood sugar with a once-daily pill. Made by Janssen, a division of Johnson & Johnson, it works by stopping glucose from being reabsorbed into the blood.

The FDA recently required Janssen to include in Invokana’s label the strongest possible warning for a prescription drug. The safety alert states that Invokana has been shown to increase the risk of leg, foot and toe amputations. The notification is based on final results of clinical trials, which show that Invokana users may have a risk of amputation that is twice as high as normal.

Janssen claimed that it could help with weight loss and lower blood pressure while providing greater blood sugar reductions than its competitors. What they failed to do was to warn of the medicine's dangers – that it increases the risk of amputation and diabetic ketoacidosis.

If you or someone you love took Invokana and then had to have a limb amputated or was diagnosed with ketoacidosis you may have a claim against its manufacturer. Read about other dangerous drugs: Opioids and Pradaxa.
