Fludarabine injection must be given under the supervision of a doctor who is experienced in giving chemotherapy medications for cancer.
Fludarabine injection can cause a decrease in the number of blood cells made by your bone marrow. This decrease may cause you to develop dangerous symptoms and may increase your risk of having a serious or life-threatening infection. Your doctor may prescribe other medications to decrease the risk that you will develop a severe infection during your treatment. Tell your doctor if you have or have ever had a low number of any type of blood cells in your blood or any condition that affects your immune system and if you have ever developed an infection because your blood cell levels were too low. If you experience any of the following symptoms, call your doctor immediately: shortness of breath; fast heartbeat; headache; dizziness; pale skin; extreme tiredness; unusual bleeding or bruising; black, tarry, or bloody stool; vomit that is bloody or that looks like coffee grounds; and fever, chills, cough, sore throat, difficult, painful, or frequent urination, or other signs of infection.
Fludarabine injection can also cause damage to the nervous system . If you experience any of the following symptoms, call your doctor immediately: seizures, agitation, confusion, and coma (loss of consciousness for a period of time).

If you experience any of the following symptoms, call your doctor immediately: dark urine, yellow skin, tiny red or purple dots on the skin, nosebleeds, heavy menstrual bleeding, blood in the urine, coughing up blood, or difficulty breathing due to bleeding in the throat.
