Binds to vascular endothelial growth factor (VEGF) and prevents the interaction of VEGF to its receptors on the surface of endothelial cells. This blocks endothelial cell proliferation and new blood vessel formation in tumor cells.

Therapeutic Effect

Believed to cause reduction of microvascularization in the tumor inhibiting the progression of metastatic disease.


Metastatic colorectal cancer, non small cell lung cancer.

Unlabeled Uses

Metastatic renal cell cancer, age-related macular degeneration.

Nursing Implications

Assessment & Drug Effects

  • Monitor for S&S of an infusion reaction (hypersensitivity); infusion should be interrupted in all patients with severe infusion reactions and appropriate therapy instituted.
  • Monitor BP at least every 2–3 wk; if hypertension develops, monitor more frequently, even after discontinuation of bevacizumab.
  • Withhold drug and promptly notify physician for S&S of CHF, hemorrhage (e.g., epistaxis, hemoptysis, or GI bleeding), or unexplained abdominal pain.
  • Lab tests: Urinalysis for proteinuria and 24 h urine if protein 2+ or greater.
  • Monitor for dizziness, lightheadedness, or loss of balance. Take appropriate safety measures.

Patient & Family Education

  • Report any of the following to the physician: bloody or black, tarry stool; changes in patterns of urination; swelling of legs or ankles; increased shortness of breath; severe abdominal pain; change in mental awareness, inability to talk or move one side of the body.
  • Women of childbearing age should use effective birth control while receiving bevacizumab.
