Dosage Guidelines & Tips
How to take Pemfexy (Intravenous)?
Use Pemfexy (Intravenous) exactly as directed on the label, or as prescribed by your doctor. Do not use in larger or smaller amounts or for longer than recommended.
Pemetrexed is given as an infusion into a vein. 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.
Call your doctor if you are sick with vomiting or diarrhea, or if you are sweating more than usual. You can easily become dehydrated while taking pemetrexed. This can lead to very low blood pressure, a serious electrolyte imbalance, or kidney failure.
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.
Call your doctor for instructions if you miss an appointment for your pemetrexed injection.
