About This Medication

What the Medication is Used For

Fludarabine Phosphate Injection and Fludarabine Phosphate for Injection is an anticancer drug. It is given by slow infusion (with a drip) into the veins (intravenously).

Fludarabine Phosphate Injection and Fludarabine Phosphate for Injection is used as a second line treatment in patients with chronic lymphocytic leukemia (CLL) and low-grade non-Hodgkin's lymphoma (Lg-NHL) who have failed other conventional treatments.

In CLL and Lg-NHL, too many abnormal lymphocytes are produced and lymph nodes start to grow in various regions of your body. The abnormal lymphocytes either do not work properly or are too young (immature) to fight infection well. If there are too many of these abnormal lymphocytes, they push aside healthy blood cells in the bone marrow where most of the new blood cells are formed. Without enough healthy blood cells, infections, anemia, bruising, excessive bleeding or even organ failure can result.

What it Does

All cells of the body produce new cells like themselves by dividing. For this purpose, the cells' genetic material (DNA) must be copied and reproduced. Fludarabine Phosphate Injection and Fludarabine Phosphate for Injection work by hindering the production of new DNA.

  • Low red blood cell count due to a break down of red blood cells (hemolytic anemia) may result in death.
  • Lung toxicity resulting in death when used in combination with pentostatin (deoxycoformycin).

BEFORE you use Fludarabine Phosphate Injection and Fludarabine Phosphate for Injection talk to your doctor if you:

  • Have a low red blood cell count;
