Using Toposar may increase your risk of developing other types of cancer, such as leukemia. Talk with your doctor about your specific risk.

Toposar can harm an unborn baby if the mother or the father is using Toposar.

• If you are a woman, do not use Toposar if you are pregnant. Use effective birth control to prevent pregnancy while you are using this medicine and for at least 6 months after your last dose.

• If you are a man, use effective birth control if your sex partner is able to get pregnant. Keep using birth control for at least 4 months after your last dose.

• Tell your doctor right away if a pregnancy occurs while either the mother or the father is using Toposar.

This medicine may affect fertility (ability to have children) in both men and women. However, it is important to use birth control to prevent pregnancy because Toposar can harm an unborn baby.

You should not breastfeed while you are using Toposar.

How is Toposar given?

Toposar is given as an infusion into a vein. A healthcare provider will give you this injection.

Toposar is usually given as part of a 4-day or 5-day treatment cycle every 3 or 4 weeks. Follow your doctor's dosing instructions very carefully.

Toposar can be harmful if it gets on your skin. If skin contact occurs, wash the area with soap and water.

Toposar can increase your risk of bleeding or infection. You will need frequent medical tests. Your cancer treatments may be delayed based on the results.

What happens if I miss a dose?

What happens if I overdose?

What should I avoid while receiving Toposar?

Do not receive a "live" vaccine while using Toposar. The vaccine may not work as well during this time, and may not fully protect you from disease. Live vaccines include measles, mumps, rubella (MMR), rotavirus, typhoid, yellow fever, varicella (chickenpox), zoster (shingles), and nasal flu (influenza) vaccine.

Avoid being near people who are sick or have infections. Tell your doctor at once if you develop signs of infection.

Avoid activities that may increase your risk of bleeding or injury. Use extra care to prevent bleeding while shaving or brushing your teeth.

What other drugs will affect Toposar?

Tell your doctor about all your other medicines, especially:

• aspirin;

• warfarin (Coumadin, Jantoven); or

• seizure mediation.

This list is not complete. Other drugs may affect Toposar, including prescription and over-the-counter medicines, vitamins, and herbal products. Not all possible drug interactions are listed here.
