Why is this medication prescribed?
Bevacizumab is used with chemotherapy to treat cancer of the colon (large intestine) or rectum that has spread to other parts of the body. Bevacizumab is also used with chemotherapy to treat certain types of lung cancer. Bevacizumab is also used to treat glioblastoma (a certain type of cancerous brain tumor) that has been already treated with other medications. Bevacizumab is also used in combination with another medication to treat renal cell cancer (RCC, a type of cancer that begins in the kidney) that has spread to other parts of the body. Bevacizumab is in a class of medications called antiangiogenic agents. It works by stopping the formation of blood vessels that bring oxygen and nutrients to tumors. This may slow the growth and spread of tumors.

How should this medicine be used?
Bevacizumab comes as a solution to administer slowly into a vein. Bevacizumab is administered by a doctor or nurse in a medical office, infusion center, or hospital. Bevacizumab is usually given once every 14 days to treat cancer of the colon or rectum, glioblastoma, or renal cell cancer and once every 3 weeks to treat lung cancer.

It should take 90 minutes for you to receive your first dose of bevacizumab. A doctor or nurse will watch you closely to see how your body reacts to bevacizumab. If you do not have any serious problems when you receive your first dose of bevacizumab, it will usually take 30 to 60 minutes for you to receive each of your remaining doses of the medication.

Other uses for this medicine
Bevacizumab has previously been used to treat breast cancer, however, further investigation by the FDA has found that the risks associated with treatment do not justify use for the benefit found in most cases. Bevacizumab is also sometimes used to treat wet age-related macular degeneration (AMD; an ongoing disease of the eye that causes loss of the ability to see straight ahead and may make it more difficult to read, drive, or perform other daily activities) and other types of cancer. Talk to your doctor about the risks of using bevacizumab to treat your condition.
