Warnings & Precautions
Before using Farxiga, tell your doctor or pharmacist:
- If you are allergic to Farxiga or any ingredients in Farxiga
- If you have had, or have risk factors for ketoacidosis
- If you have or have had liver, bladder or pancreas problems
- If you are pregnant or plan to become pregnant
- If you are breastfeeding or plan to breastfeed
Farxiga may cause your blood pressure to drop. If you feel dizzy or faint, speak to your doctor.
Ketoacidosis is a serious condition that occurs when the body does not have enough insulin to use the glucose in the blood, and the body starts to break down fat for energy. This can cause ketones to build up in the blood, making it more acidic. Contact your doctor if you experience high blood glucose levels, thirst, very dry mouth or frequent urination.
Acute Kidney Injury and Impairment in Renal Function
You should contact your doctor or emergency room immediately if you experience signs and symptoms of acute kidney injury. This is a serious condition where the kidneys suddenly stop working and cause dangerous levels of waste to build up in the body. Signs and symptoms include decreased urine or swelling in the legs or feet.
Urinary tract infections
Farxiga increases the risk of urinary tract infections and can lead to hospitalization or even death. Two of these infections are called urosepsis and pyelonephritis. Urosepsis happens when bacteria from a UTI infects the bloodstream. Pyelonephritis occurs when bacteria from a UTI invade essential kidney tissue.
You could develop low blood sugar if you take Farxiga with another medicine that can cause low blood sugar. Symptoms include shaking, sweating, fast heartbeat, dizziness, hunger, headache, and irritability.
Infections in the penis or vagina
Farxiga can cause serious infections in the penis or vagina. Get medical help right away if you have burning, itching, odor, discharge, pain, tenderness, redness or swelling of the genital or rectal area, fever, or if you don’t feel well.
Some people taking this medicine have had bladder cancer, but it is not clear if Farxiga was the actual cause. Do not use Farxiga if you have bladder cancer or a history of bladder cancer.
Pregnant or Planning to Become Pregnant
Taking Farxiga while pregnant can impact the unborn baby and cause harm, especially during the second and third trimesters. If you are a female patient and pregnant or planning to become pregnant, please speak to your doctor first before taking Farxiga.
Breastfeeding or Planning to Breastfeed
Studies have not been conducted to determine if Farxiga will pass through to human milk. Farxiga is not recommended when breastfeeding.
