|WARNING||GASTROINTESTINAL PERFORATIONS, SURGERY AND WOUND HEALING COMPLICATIONS and HEMORRHAGE
The incidence of gastrointestinal perforation, some fatal, in Bevacizumab-treated patients ranges from 0.3 to 2.4%. Discontinue Bevacizumab in patients with gastrointestinal perforation.Surgery and Wound Healing Complications
The incidence of wound healing and surgical complications, including serious and fatal complications, is increased in Bevacizumab-treated patients. Discontinue Bevacizumab in patients with wound dehiscence. The appropriate interval between termination of Bevacizumab and subsequent elective surgery required to reduce the risks of impaired wound healing/wound dehiscence has not been determined. Discontinue at least 28 days prior to elective surgery. Do not initiate Bevacizumab for at least 28 days after surgery and until the surgical wound is fully healed.HemorrhageSevere or fatal hemorrhage, including hemoptysis, gastrointestinal bleeding, central nervous systems (CNS) hemorrhage, epistaxis, and vaginal bleeding occurred up to five-fold more frequently in patients receiving Bevacizumab. Do not administer Bevacizumab to patients with serious hemorrhage or recent hemoptysis.

|Drug Interactions||May affect the PK of irinotecan.
Potentially Fatal: May affect the PK of irinotecan. Please consult detailed drug interactions before prescribing.
|Pregnancy Category (FDA)||Category C: Either studies in animals have revealed adverse effects on the foetus (teratogenic or embryocidal or other) and there are no controlled studies in women or studies in women and animals are not available. Drugs should be given only if the potential benefit justifies the potential risk to the foetus.|
|Storage||Intravenous: Store at 2-8Â°C. Diluted solutions may be stored at 2-8Â°C for up to 8 hr.|
|Pharmacology||A recombinant humanised monoclonal antibody that binds to vascular endothelial growth factor (VEGF), prevents interaction of VEGF with its receptors (Flt-1, KDR) on the surface of endothelial cells & thereby inhibits the angiogenesis that occurs during tumour growth.
Excretion: Likely to be cleared via the reticuloendothelial system.Terminal half-life: About 20 days.

Talk to your doctor about the risks of using bevacizumab.
Why is Bevacizumab 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 Bevacizumab 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 Bevacizumab
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.
Bevacizumab may be prescribed for other uses; ask your doctor for more information.

Also inform your doctor if you are taking or if you have ever taken an anthracycline (a type of chemotherapy used for breast cancer and some types of leukemia) such as daunorubicin, doxorubicin, epirubicin, or idarubicin. Your doctor may need to change the doses of your medications or monitor you carefully for side effects.
- inform your doctor if you have ever been treated with radiation therapy to the left side of your chest; and if you have or have ever had cancer that spread to your brain or spine, high blood pressure, or any condition that affects your heart or blood vessels (tubes that move blood between the heart and other parts of the body).

You should use birth control to prevent pregnancy during your treatment with bevacizumab and for at least 6 months after you stop using the medication. If you become pregnant while using bevacizumab, call your doctor. Bevacizumab may harm the fetus and increase the risk of a pregnancy loss.
