What is etoposide phosphate?

Etoposide phosphate is used to treat cancer of the lung or testicles.

Etoposide phosphate may also be used for purposes not listed in this medication guide.

Important Information

Etoposide phosphate can increase your risk of bleeding or infection. Call your doctor if you have unusual bruising or bleeding, or new signs of infection (fever, mouth sores, sore throat, trouble breathing).

Before taking this medicine

You should not use this medication if you are allergic to etoposide.

Tell your doctor if you have ever had:

  • kidney disease; or

  • if you use a blood thinner (such as warfarin) and you have routine "INR" or prothrombin time tests.

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

Etoposide can harm an unborn baby if the mother or the father is using etoposide phosphate.

  • If you are a woman, do not use etoposide 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 etoposide.

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 etoposide can harm an unborn baby.

You should not breastfeed while using etoposide.

How is etoposide phosphate given?

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

For testicular cancer: Etoposide phosphate is usually given during the first 5 days of a 21-day or 28-day treatment cycle.

For lung cancer: Etoposide phosphate is usually given for 4 or 5 days in a row.

Your doctor will determine how long to treat you with this medicine.

Tell your caregivers if you feel any burning, pain, or swelling around the IV needle when etoposide phosphate is injected.

Etoposide 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?

Call your doctor for instructions if you miss an appointment for your etoposide phosphate injection.

What happens if I overdose?

Seek emergency medical attention or call the Poison Help line at 1-800-222-1222.

What should I avoid while receiving etoposide phosphate?

Do not receive a "live" vaccine while using etoposide phosphate, or you could develop a serious infection. Live vaccines include measles, mumps, rubella (MMR), polio, 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.

Etoposide phosphate side effects

Call your doctor at once if you have:

  • pain, burning, irritation, or skin changes where the injection was given;

  • severe nausea and vomiting;

  • easy bruising, unusual bleeding, purple or red spots under your skin; or
