Possible Side Effects

  • Bone marrow depression. This is a decrease in the number of white blood cells, red blood cells, and platelets. Bone marrow depression usually occurs seven to 14 days after the drug is given and may increase your risk of infection, fatigue, and bleeding.
  • Soreness of the mouth and throat. You may have red areas, white patches, or sores that are painful.
  • Nausea and vomiting. These symptoms may occur within three hours after you receive the drug and may last up to eight hours.

This cannot be determined before your therapy. In men, this drug may interfere with your ability to make sperm, but it should not change your ability to have sexual relations. In women, menstrual bleeding may become irregular or stop while you are receiving this drug. Do not assume that you cannot become pregnant if you do not have a menstrual period.
