Everolimus

Everolimus (Afinitor) is used to treat advanced renal cell carcinoma (RCC; cancer that begins in the kidneys) that has already been treated unsuccessfully with other medications. Everolimus (Afinitor) is also used to treat a certain type of advanced breast cancer that has already been treated with at least one other medication. Everolimus (Afinitor) is also used to treat a certain type of cancer of the pancreas, stomach, intestines, or lungs that has spread or progressed and that cannot be treated with surgery. Everolimus (Afinitor) is also used to treat kidney tumors in people with tuberous sclerosis complex (TSC; a genetic condition that causes tumors to grow in many organs). Everolimus (Afinitor and Afinitor Disperz) is also used to treat subependymal giant cell astrocytoma (SEGA; a type of brain tumor) in adults and children 1 year of age and older who have TSC. Everolimus (Afinitor Disperz) is also used along with other medications to treat certain types of seizures in adults and children 2 years of age and older who have TSC. Everolimus (Zortress) is used with other medications to prevent transplant rejection (attack of the transplanted organ by the immune system of the person who received the organ) in certain adults who have received kidney transplants. Everolimus is in a class of medications called kinase inhibitors. Everolimus treats cancer by stopping cancer cells from reproducing and by decreasing blood supply to the cancer cells. Everolimus prevents transplant rejection by decreasing the activity of the immune system.

Everolimus comes as a tablet to take by mouth and as a tablet to suspend in water and take by mouth. When everolimus is taken to treat kidney tumors, SEGA, or seizures in people who have TSC; RCC; or breast, pancreatic, stomach, intestine, or lung cancer, it is usually taken once a day. When everolimus is taken to prevent transplant rejection, it is usually taken twice a day (every 12 hours) at the same time as cyclosporine. Everolimus should either always be taken with food or always without food. Take everolimus at around the same time(s) every day. Follow the directions on your prescription label carefully, and ask your doctor or pharmacist to explain any part you do not understand. Take everolimus exactly as directed. Do not take more or less of it or take it more often than prescribed by your doctor.

Everolimus tablets come in individual blister packs that can be opened with scissors. Do not open a blister pack until you are ready to swallow the tablet it contains.

You should take either everolimus tablets or everolimus tablets for oral suspension. Do not take a combination of both of these products.

Swallow the tablets whole with a full glass of water; do not split, chew, or crush them. Do not take tablets that have been crushed or broken. Tell your doctor or pharmacist if you are not able to swallow the tablets whole.

If you are taking the tablets for oral suspension (Afinitor Disperz), you must mix them with water before use. Do not swallow these tablets whole, and do not mix them with juice or any liquid other than water. Do not prepare the mixture more than 60 minutes before you plan to use it, and dispose of the mixture if it is not used after 60 minutes. Do not prepare the medication on a surface that you use to prepare or eat food. If you will be preparing the medication for someone else, you should wear gloves to prevent contact with the medication. If you are pregnant or plan to become pregnant, you should avoid preparing the medication for someone else, because contact with everolimus may harm your unborn baby.

You can mix the tablets for oral suspension in an oral syringe or in a small glass. To prepare the mixture in an oral syringe, remove the plunger from a 10-mL oral syringe and place the prescribed number of tablets in the barrel of the syringe without breaking or crushing the tablets. You can prepare up to 10 mg of everolimus in a syringe at one time, so if your dose is greater than 10 mg, you will need to prepare it in a second syringe. Replace the plunger in the syringe and draw about 5 mL of water and 4 mL of air into the syringe and place the syringe into a container with the tip pointing up. Wait 3 minutes to allow the tablets to go into suspension. then pick up the syringe and gently turn it up and down it five times. Place the syringe into the patient's mouth and push the plunger to administer the medication. After the patient has swallowed the medication, refill the same syringe with 5 mL of water and 4 mL of air and swirl the syringe to rinse out any particles that are still in the syringe. Give this mixture to the patient to be sure that he or she receives all of the medication.

To prepare the mixture in a glass, place the prescribed number of tablets into a small drinking glass that holds no more than 100 mL (about 3 ounces) without crushing or breaking the tablets. You can prepare up to 10 mg of everolimus in a glass at one time, so if your dose is greater than 10 mg, you will need to prepare it in a second glass. Add 25 mL (about 1 ounce) of water to the glass. Wait 3 minutes and then gently stir the mixture with a spoon. Have the patient drink the entire mixture immediately. Add another 25 mL of water to the glass and stir with the same spoon to rinse out any particles that are still in the glass. Have the patient drink this mixture to be sure that he or she receives all of the medication.

Your doctor may adjust your dose of everolimus during your treatment depending on the results of your blood tests, your response to the medication, side effects you experience, and changes in other medications that you take with everolimus. If you are taking everolimus to treat SEGA or seizures, your doctor will adjust your dose not more often than once every 1 to 2 weeks, and if you are taking everolimus to prevent transplant rejection, your doctor will adjust your dose not more often than once every 4 to 5 days. Your doctor may stop your treatment for a time if you experience severe side effects. Talk to your doctor about how you are feeling during your treatment with everolimus.
