What is Afinitor?

Afinitor (everolimus) is a cancer medicine that interferes with the growth of cancer cells and slows their spread in the body.

Afinitor is used to treat certain types of kidney cancer, breast cancer, or brain tumor. It is also used to treat certain types of advanced or progressive tumors of the stomach, intestines, or pancreas.

Afinitor is also used to treat certain non-cancerous (benign) tumors of the brain or kidney in people with a certain genetic condition called tuberous sclerosis complex.

This medication guide provides information about the Afinitor brand of everolimus. Zortress is another brand of everolimus used to prevent organ rejection after a kidney transplant.

Important information

Afinitor can cause serious and sometimes fatal side effects. Call your doctor right away if you have: signs of infection--fever, chills, skin rash, joint pain, tiredness; lung problems--cough, chest pain, wheezing, shortness of breath; kidney problems--swelling, little or no urination; or liver problems--loss of appetite, dark urine, yellowing of your skin or eyes, or upper stomach pain.

If you have ever had hepatitis B, Afinitor can cause this condition to come back or get worse.

You may be more likely to have an allergic reaction if you take an "ACE inhibitor" heart or blood pressure medication while you are taking Afinitor. Tell your doctor about all your current medicines and any you start or stop using.

Before taking this medicine, tell your doctor if you have a breathing disorder such as asthma or COPD, liver disease (or a history of hepatitis B), an active infection, diabetes or high blood sugar, or high cholesterol.

Do not use Afinitor if you are pregnant. It could harm the unborn baby. Use effective birth control while you are using this medicine and for at least 8 weeks after your treatment ends.

Before taking this medicine

You should not use Afinitor if you are allergic to everolimus, sirolimus (Rapamune), or temsirolimus (Torisel).

To make sure Afinitor is safe for you, tell your doctor if you have ever had:

  • an active or chronic infection;

  • liver disease, especially hepatitis B;

  • kidney disease;

  • diabetes or high blood sugar;

  • high cholesterol;

  • if you are scheduled to receive any vaccine; or

  • high blood pressure.

Everolimus can harm an unborn baby. Use effective birth control to prevent pregnancy while you are using this medicine, whether you are a man or a woman. Afinitor use by either parent may cause birth defects.

If you are a woman, keep using birth control for at least 8 weeks after your last dose of Afinitor. If you are a man, keep using birth control for at least 4 weeks after your last dose. Tell your doctor right away if a pregnancy occurs while either the mother or the father is using everolimus.

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 everolimus may harm the baby if a pregnancy does occur.

It is not known whether everolimus passes into breast milk or if it could harm a nursing baby. You should not breast-feed while using this medicine and for at least 2 weeks after your last dose.

How should I take Afinitor?

Take Afinitor exactly as prescribed by your doctor. Follow all directions on your prescription label. Your doctor may occasionally change your dose. Do not take this medicine in larger or smaller amounts or for longer than recommended.

Take this medicine at the same time each day. You may take the medicine with or without food, but take it the same way each time.

Take the Afinitor regular tablet with a full glass of water. Do not crush, chew, or break the tablet. Swallow the pill whole.

Do not take an Afinitor regular tablet together with a dispersible tablet. Use only one form of this medicine.

Do not swallow the dispersible tablet (Afinitor Disperz) whole. Place the tablet into about 2 tablespoons of water and allow the tablet to disperse in the liquid for at least 3 minutes. Stir gently and drink this mixture right away. The dispersed tablet may also be taken with an oral syringe. Wear latex gloves while handling the Disperz tablet.

Read all patient information, medication guides, and instruction sheets provided to you. Ask your doctor or pharmacist if you have any questions.

Everolimus can lower blood cells that help your body fight infections and help your blood to clot. This can make it easier for you to bleed from an injury or get sick from being around others who are ill. Your blood may need to be tested often.

If you have ever had hepatitis B, everolimus can cause this condition to come back or get worse. You will need frequent blood tests to check your liver function during treatment and for several months after you stop using this medicine.

If you need surgery, tell the surgeon ahead of time that you are using Afinitor. Your surgical incisions or other wounds may take longer to heal while you are taking this medicine.

Store at room temperature in the original container, away from moisture, heat, and light. Keep unused dispersible tablets in the foil blister pack.

This medicine can pass into body fluids (urine, feces, vomit). Caregivers should wear rubber gloves while cleaning up a patient's body fluids, handling contaminated trash or laundry or changing diapers. Wash hands before and after removing gloves. Wash soiled clothing and linens separately from other laundry.

Grapefruit and grapefruit juice may interact with everolimus and lead to unwanted side effects. Avoid the use of grapefruit products while taking Afinitor.
