Topotecan may cause severe and sometimes fatal bone marrow suppression and blood problems. These blood problems may increase the risk of developing a severe infection. Topotecan should not be used in patients who have low platelet levels or very low white blood cell levels. Contact your doctor at once if you have symptoms of an infection (eg, fever, chills, persistent sore throat, painful urination), unusual bruising or bleeding, or unusual fatigue. Frequent blood tests will be performed to monitor for side effects. Be sure to keep all doctor and lab appointments.
Topotecan is used for:
Treating certain types of ovarian or lung cancer that do not respond well to other types of cancer treatment. It may be used to treat certain types of cervical cancer that cannot be treated by surgery or radiation therapy. It may also be used for other conditions as determined by your doctor.
Topotecan is an antineoplastic. It works by killing certain cancer cells.
