Avastin® (bevacizumab) is given as an infusion. That means you get Avastin through a small needle in your vein or through a port, which is a device placed under your skin.

Because Avastin is given as an infusion, infusion reactions may occur. Avastin infusions will be stopped by your doctor or nurse if infusion reactions are severe.

Your doctor or nurse will monitor you for signs of an infusion reaction, which may include:

  • High blood pressure or severe high blood pressure that may lead to stroke
  • Difficulty breathing
  • Decreased oxygen in red blood cells
  • A serious allergic reaction
  • Chest pain
  • Headache
  • Tremors
  • Excessive sweating

How often do I get Avastin infusions?

Avastin infusions are given every 2 or 3 weeks to treat your metastatic colorectal cancer. Because Avastin can be scheduled on the same day you get your IV 5-FU-based chemotherapy, it may not require extra visits to an infusion center.

Avastin is given every 2 weeks for metastatic colorectal cancer (mCRC) patients starting Avastin for first- or second-line treatment.

Avastin is given every 3 weeks for metastatic colorectal cancer (mCRC) patients continuing on Avastin for second-line treatment after a first-line treatment that included Avastin.

How long do my Avastin infusions take?

You always get the same dose of Avastin. If your Avastin infusions are tolerated, they can take as little as 30 minutes.
