Examples

Fludarabine is available as an oral and intravenous (IV) medicine.

How It Works

Fludarabine is an antimetabolite medicine. It causes cell death by interfering with the way genetic material (DNA) in the cell multiplies.

Why It Is Used

Fludarabine is used in combination with other medicines to treat chronic lymphocytic leukemia (CLL) and non-Hodgkin's lymphoma (NHL).

How Well It Works

Fludarabine is an effective treatment for chronic lymphocytic leukemia (CLL) that has not responded to other types of chemotherapy, such as chlorambucil or cyclophosphamide. Studies are ongoing to find out the safety and effectiveness of fludarabine in people who have not received other types of chemotherapy or who are responding to other types of chemotherapy.

Side Effects

Side effects are common with fludarabine and can include:

• Severe rapid destruction of red blood cells (hemolytic anemia).
• Decreased platelet counts (thrombocytopenia), which may lead to bleeding in the digestive tract, causing tarry stools.
• Joint pain.
• Blood in urine or stools.
• Blurred vision.
• Chest pain or discomfort.
• Diarrhea.
• Cough, wheezing, hoarseness, or shortness of breath.
