Avastin^® (bevacizumab) is a medication approved to treat colorectal cancer and lung cancer. It is also commonly used in an "off-label" fashion to treat macular degeneration. At this time, there are no known Avastin drug interactions. However, because specific studies to check for drug interactions have not been performed, it is possible that interactions exist that are not currently known.

 

One study suggested that Avastin may affect how the body handles irinotecan (Camptosar^®), a chemotherapy medication, possibly increasing the risk of irinotecan side effects. However, it is not certain that Avastin caused these changes or if they were random.

 

Because it is possible that not all Avastin drug interactions are known at this time, you should talk with your pharmacist or healthcare provider on a regular basis about any specific drug interactions that may apply to you.
