How does this medication work? What will it do for me?
Etoposide belongs to the group of cancer-fighting medications called antineoplastics. Etoposide kills cancer cells by interfering with the genetic material DNA, which is necessary for their growth and reproduction. Etoposide is used alone or in combination with other antineoplastic medications to treat many types of cancer. These include certain types of lung cancer, lymphoma (cancer of the lymph cells), and cancers of the testicles.
Your doctor may have suggested this medication for conditions other than those listed in these drug information articles. As well, some forms of this medication may not be used for all of the conditions discussed here. If you have not discussed this with your doctor or are not sure why you are being given this medication, speak to your doctor. Do not stop receiving this medication without consulting your doctor.
What form(s) does this medication come in?
Each mL contains 20 mg of etoposide. Nonmedicinal ingredients: benzyl alcohol (as preservative), anhydrous citric acid, ethanol, polyethylene glycol, and polysorbate 80.
How should I use this medication?
The recommended dose and dosing schedule of etoposide varies according to the specific condition being treated, the response to therapy, and the other medications or treatments being used. The dose administered is also based on body size.
Many things can affect the dose of medication that a person needs, such as body weight, other medical conditions, and other medications. If your doctor has recommended a dose different from the ones listed here, do not change the way that you are receiving the medication without consulting your doctor.
Etoposide is available as an injectable preparation or as a capsule to be taken by mouth. It should only be prescribed or given by health care professionals familiar with the use of chemotherapy medications to treat cancer.
The injectable form is injected into a vein through a site on your skin that has been specially prepared for this purpose. This form of etoposide is always given under the direct supervision of a doctor. Very careful handling of this medication is required. It is always administered in a hospital or similar setting with access to sterile equipment for preparation.
Etoposide capsules should be taken on an empty stomach. Etoposide often causes nausea and vomiting, but it is very important that you continue to take the medication, even if you begin to feel ill. Your doctor, nurse, or pharmacist can advise you on how to reduce the effects of nausea and vomiting. If you vomit shortly after taking a dose of etoposide, call your doctor to determine whether you should take the dose again or wait until the next dose.
It is important to take this medication exactly as prescribed by your doctor. If you miss a dose, take it as soon as possible and continue with your regular schedule. If it is almost time for your next dose, skip the missed dose and continue with your regular dosing schedule. Do not take a double dose to make up for a missed one. If you are not sure what to do after missing a dose, contact your doctor or pharmacist for advice.
As well as interfering with the genetic material (DNA) of cancer cells, etoposide can interfere with some of your normal cells. This can cause a number of side effects. Keep track of any side effects and report them to your doctor, as suggested in the section "What side effects are possible with this medication?"
Store the capsule form of this medication at room temperature, and keep it out of the reach of children.

Are there any other precautions or warnings for this medication?
Before you begin using a medication, be sure to inform your doctor of any medical conditions or allergies you may have, any medications you are taking, whether you are pregnant or breast-feeding, and any other significant facts about your health. These factors may affect how you should use this medication.
Allergic reactions: Allergic reactions, including difficulty breathing and swelling of the throat and mouth, can occur with the use of this medication. Tell your doctor immediately if you experience any of these symptoms.
Blood clotting: This medication can reduce the number of platelet cells in the blood. Platelets help the blood to clot, and a shortage could make you bleed more easily. Tell your doctor of any signs that your blood is not clotting as quickly as usual. Such symptoms may include black and tarry stools, blood in the urine, easy bruising, or cuts that won't stop bleeding.
Infection: As well as killing cancer cells, etoposide can reduce the number of cells that fight infection in the body (white blood cells). If possible, avoid contact with people who have contagious infections. Tell your doctor if you begin to notice the signs of an infection such as fever or chills, severe diarrhea, shortness of breath, prolonged dizziness, headache, stiff neck, weight loss, or listlessness. Your doctor will do blood tests regularly to monitor the number of specific types of blood cells in your blood.
Kidney function: Etoposide can reduce kidney function. If you have kidney disease or reduced kidney function, discuss with your doctor how this medication may affect your medical condition, and how your medical condition may affect the dosing and effectiveness of this medication. Your doctor will routinely monitor your kidney function with blood tests.
Liver function: Etoposide can reduce liver function. If you have liver disease or reduced liver function, discuss with your doctor how this medication may affect your medical condition, and how your medical condition may affect the dosing and effectiveness of this medication. Your doctor will routinely monitor your kidney function with blood tests. Contact your doctor as soon as possible if you notice signs of decreased liver function, such as yellowing of the eyes and skin, dark urine, pale stools, or abdominal pain with nausea and vomiting.
Pregnancy: Etoposide can cause harm to the unborn baby when it is taken by pregnant women. It should not be used during pregnancy unless the benefits outweigh the risks. If you become pregnant while taking this medication, contact your doctor immediately.
Etoposide can cause changes to sperm in men, decreasing fertility. Women and men receiving etoposide should use effective contraceptive methods.
Breast-feeding: This medication passes into breast milk. If you are a breast-feeding mother and are taking etoposide, it may affect your baby. Talk to your doctor about whether you should continue breast-feeding.
Children: The safety and effectiveness of using this medication for children have not been clearly established. It should only be prescribed or given by health care professionals familiar with the use of chemotherapy medications to treat cancer in children.
