What is pemetrexed?
Pemetrexed is a cancer medication that interferes with the growth and spread of cancer cells in the body.
Pemetrexed is used to treat non-small cell lung cancer after other cancer medications have been tried without successful treatment.
Pemetrexed is also used with another medication called cisplatin to treat mesothelioma, a form of lung cancer associated with exposure to asbestos.
Pemetrexed may also be used for purposes not listed in this medication guide.
What is the most important information I should know about pemetrexed?
Follow all directions on your medicine label and package. Tell each of your healthcare providers about all your medical conditions, allergies, and all medicines you use.
What should I discuss with my healthcare provider before receiving pemetrexed?
You should not receive this medication if you are allergic to pemetrexed.
To make sure pemetrexed is safe for you, tell your doctor if you have:
kidney disease (especially if you take ibuprofen (Advil, Motrin) or other nonsteroidal anti-inflammatory drugs, or NSAIDs);
a weak immune system; or
excess fluid in the space around your lung, liver, or other internal organs, including pleural effusion (fluid around the lungs) or ascites (fluid around the liver).
Do not use pemetrexed if you are pregnant. It could harm the unborn baby. Use effective birth control to avoid pregnancy during your treatment with pemetrexed. Follow your doctor's instructions about how long to prevent pregnancy after your treatment ends.
It is not known whether pemetrexed passes into breast milk or if it could harm a nursing baby. You should not breast-feed while you are using pemetrexed.
How is pemetrexed given?
Pemetrexed is injected into a vein through an IV. A healthcare provider will give you this injection.
Pemetrexed is usually given every 3 weeks. Your doctor will determine how many treatment cycles you should receive.
To prevent certain side effects of pemetrexed, you will need to take folic acid supplements and receive vitamin B12 injections (starting 7 days before your first dose of pemetrexed). Take only the amount of folic acid that your doctor has prescribed.
Your doctor may also prescribe steroid medication to reduce certain side effects of pemetrexed. Follow your doctor's dosing instructions very carefully.
Pemetrexed can lower blood cells that help your body fight infections and help your blood to clot. Your blood will need to be tested often. Your cancer treatments may be delayed based on the results of these tests.
What happens if I miss a dose?
Call your doctor for instructions if you miss an appointment for your pemetrexed injection.
What happens if I overdose?

What should I avoid while receiving pemetrexed?
Avoid being near people who are sick or have infections. Tell your doctor at once if you develop signs of infection.
Avoid activities that may increase your risk of bleeding or injury. Use extra care to prevent bleeding while shaving or brushing your teeth.
