What is Afinitor?
Afinitor 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.
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.
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 everolimus 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.

Afinitor can harm an unborn baby or cause birth defects if the mother or the father is using this medicine.

How should I take Afinitor?
Take Afinitor exactly as prescribed by your doctor. Follow all directions on your prescription label and read all medication guides or instruction sheets. Your doctor may occasionally change your dose.
Take Afinitor at the same time each day. You may take the medicine with or without food, but take it the same way each time.
Do not take a regular tablet together with a dispersible tablet. Use only one form of this medicine.
Read and carefully follow any Instructions for Use provided with your medicine. Ask your doctor or pharmacist if you do not understand these instructions.
Afinitor can increase your risk of bleeding or infection by changing the way your immune system works. You will need frequent medical tests.
If you've ever had hepatitis B, using Afinitor can cause this virus to become active or get worse. You may need frequent liver function tests while using this medicine and for several months after you stop.

What to avoid
Do not receive a "live" vaccine while using Afinitor, and avoid coming into contact with anyone who has recently received a live vaccine. There is a chance that the virus could be passed on to you. Live vaccines include measles, mumps, rubella (MMR), polio, rotavirus, typhoid, yellow fever, varicella (chickenpox), and zoster (shingles).
Grapefruit may interact with everolimus and lead to unwanted side effects. Avoid the use of grapefruit products.
If you develop mouth sores or ulcers, avoid using mouthwashes or applying medicines that contain alcohol, peroxide, iodine, or thyme. Your doctor may prescribe a steroid mouthwash if your mouth sores are severe.
