Fludarabine

• Fludarabine is used to treat B-cell chronic lymphocytic leukaemia (CLL), particularly in patients with advanced disease or when previous treatment with standard medicines has not worked

When should one not use Fludarabine

• If you have a severe allergy to fludarabine or any of its ingredients.

Common side effects of this drug are:

• Bone marrow suppression leading to neutropenia (low white blood cell count), anemia, and thrombocytopenia (low platelet count)
• Severe immunosuppression and increased susceptibility to opportunistic infections
• Nausea, vomiting, diarrhea, and loss of appetite
• Fatigue, asthenia (weakness), and fever
• Cough and upper respiratory tract infections
• Peripheral neuropathy (numbness, tingling, or weakness in the extremities)
• Edema, skin rash, and stomatitis (mouth sores)
• Visual disturbances
• Elevated liver enzymes and kidney function changes
• Severe, life-threatening opportunistic infections
• Autoimmune hemolytic anemia (AIHA) or other autoimmune cytopenias
• Severe neurotoxicity (including confusion, agitation, seizures, peripheral neuropathy, coma, or blindness)
• Tumor lysis syndrome (metabolic imbalances due to rapid cancer cell breakdown)
• Secondary malignancies (long-term risk)

Other General Warnings

• You experience a fever, chills, or any signs of an infection, as prompt medical evaluation is critical due to suppressed immunity.
• You notice unusual pale skin, extreme fatigue, or dark urine, which can be signs of autoimmune hemolytic anemia.
• You develop neurological changes, such as confusion, agitation, weakness, or vision loss.
• You require a blood transfusion, as any blood products given during or after fludarabine therapy must be irradiated to prevent transfusion-associated graft-versus-host disease.
• If you need a blood transfusion: Tell your doctor that you are receiving fludarabine, as irradiated blood products may be required during and after treatment to reduce the risk of a serious transfusion-related complication.
• If you have kidney problems: Tell your doctor, as kidney function affects how fludarabine is removed from the body removes fludarabine and your treatment may need to be adjusted.
• Keep all scheduled blood test appointments so your doctor can monitor your blood cell counts.
• Report fever, chills, persistent cough, or other signs of infection immediately, as fludarabine can weaken the immune system.
• Tell your doctor if you notice unusual bruising, tiny red spots on the skin, or bleeding, which may indicate a low platelet count.
• Report confusion, severe headache, vision changes, numbness, or other new neurological symptoms immediately.
• Tell all your healthcare providers that you are receiving fludarabine before any medical procedure or blood transfusion, as special blood products may be required during and after treatment.
• Keep out of the reach of children and pets in a secure medical environment.
• Clinical staff manage proper disposal of vials, infusion bags, and administration equipment following hospital biomedical waste protocols.

How Does It Work?

Interactions with other medicines

• Avoid or discuss live vaccines with your doctor during and after treatment, as your severely suppressed immune system can increase the risk of serious infections.
• Concurrent use with pentostatin is not recommended because of the risk of severe and potentially fatal pulmonary toxicity.
• Tell your doctor about all prescription medicines, over-the-counter medicines, vitamins, and herbal supplements you take, especially medicines that weaken the immune system or reduce blood cell counts.
