What is Afinitor?

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

The Afinitor brand of everolimus is used to treat certain types of kidney cancer, breast cancer, or brain tumor. It is usually given after other cancer medications have been tried without successful treatment.

Afinitor is also used to treat non-cancerous (benign) kidney tumors, and certain types of advanced or progressive tumors of the pancreas.

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 to make sure you get the best results. Do not take this medicine in larger or smaller amounts or for longer than recommended.

Afinitor should be taken at the same time each day. You may take Afinitor with or without food, but take it the same way each time.

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

Do not crush, chew, or break an regular tablet. Swallow the pill whole.

Do not swallow the dispersible tablet (Afinitor Disperz) whole. Place it into a glass with 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. To make sure you get the entire dose, add a little more liquid to the same glass, swirl gently and drink right away.

The Afinitor Disperz tablet may also be taken with an oral syringe as follows: Place a tablet into the oral syringe and draw 5 milliliters (cc) of water and 4 milliliters (cc) of air into the syringe. Set the syringe with the tip up in a small container and allow the tablet to disperse in the liquid for at least 3 minutes. Turn the syringe upside down 5 times and then empty the syringe into your mouth. Refill the syringe with water, shake gently, and empty into your mouth.

Afinitor 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. Visit your doctor regularly.

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 each tablet in its blister pack until you are ready to take it.

If you have hepatitis B you may develop liver symptoms after you stop taking this medication, even months after stopping. Your doctor may want to check your liver function for several months after you stop using this medicine.

What should I avoid?

Everolimus can pass into body fluids (including urine, feces, vomit, semen, vaginal fluid).
