What is the most important information I should know about taking HYCAMTIN capsules?

HYCAMTIN capsules can cause serious side effects:

Decreased blood counts. Taking HYCAMTIN affects your bone marrow and can cause a severe decrease in your blood cell counts (bone marrow suppression) - neutrophils (a type of white blood cell important in fighting bacterial infections), red blood cells (blood cells that carry oxygen to the tissues), and platelets (important for clotting and control of bleeding).

• You should have blood tests regularly to check your blood counts. A decrease in neutrophils (neutropenia) may affect how your body fights infection.
• Your healthcare provider will tell you if your blood counts are too low before you begin treatment with HYCAMTIN.
• Your dose of HYCAMTIN may need to be changed or stopped until your blood counts recover enough after each cycle of treatment.
• Call your healthcare provider right away if you get any of the following signs of infection:
• fever (temperature of 100.5°F or greater)
  • chills
  • cough
  • burning or pain on urination
