FARXIGA may cause serious side effects including:

• Ketoacidosis. FARXIGA can cause ketoacidosis, a serious condition which may require hospitalization and lead to death. People with type 1 diabetes, type 2 diabetes, or pancreas problems have a high risk of getting ketoacidosis. Signs and symptoms may include nausea, tiredness, vomiting, trouble breathing, abdominal pain, and ketones in your urine or blood. If you get any of these symptoms, stop taking FARXIGA and call your healthcare provider right away. If possible, check for ketones in your urine or blood, even if your blood sugar is less than 250 mg/dL
• Dehydration (the loss of body water and salt), which may cause you to feel dizzy, faint, lightheaded, or weak, especially when you stand up (orthostatic hypotension). There have been reports of sudden kidney injury in people with type 2 diabetes who are taking FARXIGA. You may be at a higher risk of dehydration if you take medicines to lower your blood pressure, including water pills (diuretics); are age 65 or older; are on a low salt diet, or have kidney problems. Talk to your healthcare provider about what you can do to prevent dehydration including how much fluid you should drink on a daily basis. Call your healthcare provider right away if you reduce the amount of food or liquid you drink, or if you experience vomiting or diarrhea
• Serious urinary tract infections (UTI), some that lead to hospitalization, occurred in people taking FARXIGA. Tell your healthcare provider if you have any signs or symptoms of UTI including a burning feeling when passing urine, a need to urinate often, the need to urinate right away, pain in the lower part of your stomach (pelvis), or blood in the urine with or without fever, back pain, nausea, or vomiting
• Low blood sugar (hypoglycemia) can occur if you take FARXIGA with another medicine that can cause low blood sugar, such as sulfonylureas or insulin. Symptoms of low blood sugar include shaking, sweating, fast heartbeat, dizziness, hunger, headache, and irritability. Follow your healthcare provider's instructions for treating low blood sugar
• Bacterial infections under the skin of the genitals and areas around them. Rare but serious infections that cause severe tissue damage under the skin of the genitals and areas around them have happened with FARXIGA. This infection has happened in women and men and may lead to hospitalization, surgeries, and death. Seek medical attention immediately if you have fever or you are feeling very weak, tired or uncomfortable and you also develop any pain or tenderness, swelling, or redness of the skin in the genitals and areas around them
• Vaginal yeast infections in women who take FARXIGA. Talk to your healthcare provider if you experience vaginal odor, white or yellowish vaginal discharge (discharge may be lumpy or look like cottage cheese), or vaginal itching
• Yeast infection of skin around the penis (balanitis) in men who take FARXIGA. Talk to your healthcare provider if you experience redness, itching, or swelling of the penis; rash of the penis; foul smelling discharge from the penis; or pain in the skin around the penis. Certain uncircumcised men may have swelling of the penis that makes it difficult to pull back the skin around the tip of the penis
