Special Warning(s) with Avastin:
- Avastin may cause gastrointestinal perforation (holes in the stomach, intestines or colon) requiring surgery to repair.
- Avastin may impair wound healing or cause wounds to open up. Avastin should not be started for at least 28 days following major surgery and full wound healing, and should be stopped before a scheduled surgery.
- Mild bleeding (such as nosebleeds) is common in patients who receive Avastin. Serious bleeding from the lungs or digestive system, requiring blood transfusions, occur in less than 5% of patients receiving Avastin. When very severe, patients have died from blood loss.
- Avastin may cause a severe increase in blood pressure so patients receiving Avastin should have their blood pressure checked regularly.
- Avastin may cause proteinuria (protein in the urine, a sign of kidney damage).
- Avastin may cause blood clots. The chances of blood clots are highest in patients who are elderly.
- Avastin may cause congestive heart failure (failure of the heart to pump blood well) especially when given with chemotherapy that is known to damage the heart (such as doxorubicin).
General Precautions with Avastin:
- Avastin should be used with caution in patients who are allergic to Avastin or to any of the ingredients in Avastin.
