Etoposide phosphate

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

Etoposide phosphate may also be used for other reasons that are not mentioned in this medication guide.

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 decide how long you will receive 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.

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

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.

Get emergency medical help if you have signs of an allergic reaction (hives, difficulty breathing, swelling in your face or throat) or a severe skin reaction (fever, sore throat, burning eyes, skin pain, red or purple skin rash with blistering and peeling).

Etoposide phosphate may cause serious side effects. Call your doctor right away if you have:

• pain, burning, irritation, or skin changes where the injection was given;
• severe nausea and vomiting;

• low white blood cell counts—fever, mouth sores, skin sores, sore throat, cough, trouble breathing.

Common side effects of etoposide phosphate may include:
