A nurse or other trained health professional will give you this medicine in a medical facility. It is given through a needle placed into one of your veins.
Topotecan is usually given every day for 3 to 5 days. This 3-day or 5-day treatment is given again every 21 days until your body responds to the medicine. Each treatment usually takes at least 30 minutes.
Topotecan often causes nausea and vomiting. It is very important that you continue to receive the medicine even if it makes you feel ill. Ask your doctor for ways to lessen these effects.
