Fludarabine injection must be administered under the direction of a physician with training in administering chemotherapy drugs for cancer.

Your bone marrow’s capacity to produce blood cells may be reduced as a result of fludarabine injection. Your risk of getting a serious or life-threatening infection may rise as a result of this decline and you might experience risky symptoms. To reduce the possibility that you’ll experience a serious infection while receiving therapy, your doctor can advise additional medications. Inform your doctor if you have or have ever had an immune system disorder, a low quantity of any sort of blood cells, or if you ever got an infection because your blood cell levels were too low. Call your doctor right away if you have any of the following signs or symptoms: Breathlessness, rapid heartbeat, headache, dizziness, pale skin, extreme fatigue, unusual bleeding or bruising, black, tarry, or bloody stool, bloody or coffee-ground-like vomit, as well as fever, chills, cough, sore throat, difficult, painful, or frequent urination, or other infection-related symptoms.

The nervous system may also be damaged by fludarabine injection. Call your doctor right away if you have any of the following symptoms: convulsions, agitation, disorientation, and coma (prolonged loss of consciousness).

A dangerous or even fatal illness where the body fights and kills its own blood cells might result with fludarabine injection. If you have ever experienced this symptom after taking fludarabine in the past, let your doctor know. Call your doctor right away if you have any of the following symptoms: Blood in the urine, dark urine, yellow skin, tiny red or purple spots on the skin, nosebleeds, severe menstrual bleeding, coughing up blood, or trouble breathing because of throat bleeding are all signs of blood loss.

People with chronic lymphocytic leukemia who combined fludarabine injection and pentostatin (Nipent) were at a high risk of suffering serious lung damage, according to a clinical research. This lung damage did, in some circumstances, result in death. As a result, your doctor won’t advise you to take pentostatin (Nipent) and fludarabine injection at the same time.

Keep all of your appointments with your physician and the lab. In order to monitor your body’s reaction to fludarabine injection, your doctor will prescribe a number of tests.

Discuss the dangers of obtaining an injection of fludarabine with your doctor.

Why is this medication prescribed?

Adults with chronic lymphocytic leukemia (CLL; a form of white blood cell malignancy) who have had at least one other treatment but have not improved are treated with fludarabine injection. The drug fludarabine injection belongs to the group of drugs known as purine analogs. It functions by reducing or halting the development of cancer cells within your body.

How should this medicine be used?

A doctor or nurse will administer the fludarabine injection over the course of 30 minutes intravenously (into a vein) in a doctor’s office or hospital outpatient clinic. The drug is available as a powder to be mixed with fluid. Typically, it is injected once every day for five days straight. This time of treatment is known as a cycle, and it may be repeated every 28 days for a number of cycles.

If you encounter certain adverse effects, your doctor may decide to postpone your treatment or change your dose. Tell your doctor how you are feeling throughout your fludarabine injection treatment.

Other uses for this medicine

Non-Hodgkin’s lymphoma (NHL; a cancer that starts in a type of white blood cell that often fights infection) and mycosis fungoides (a type of lymphoma that affects the skin) are two more conditions that are occasionally treated with fludarabine injection. The dangers of using this drug for your illness should be discussed with your doctor.

Ask your doctor or pharmacist for more details if you believe this drug should be used for something else.
