If you get any of these symptoms during treatment with Farxiga, if possible, check for ketones in your urine, even if your blood sugar is less than 250 mg/dL.

Sometimes people also may have a fever, back pain, nausea or vomiting.

If you take Farxiga with another medicine that can cause low blood sugar, such as a sulfonylurea or insulin, your risk of getting low blood sugar is higher.

Necrotizing fasciitis of the perineum may lead to hospitalization, may require multiple surgeries, and may lead to death.
