CeeNU often decreases bone marrow function and lowers the number of white blood cells and platelets in your blood. This may increase your risk for severe infection or bleeding problems, especially if you already have bone marrow suppression. The risk is greater if you take CeeNU more often than once every 6 weeks, take it in high doses, or take it for a long period of time. Tell your doctor right away if you experience symptoms such as fever, chills or persistent sore throat, unusual bruising or bleeding, or unusual tiredness or weakness.
You will need to have blood tests every week for at least 6 weeks after each single dose of CeeNU. Your doctor may change your dose of CeeNU based on these tests.
