Avastin and Breastfeeding: An Overview
At this time, it is unknown if
Avastin® (
bevacizumab) passes through breast milk in humans, although similar molecules are known to pass through breast milk. The manufacturer of the drug does not recommend that women breastfeed while taking it. Therefore, if you are breastfeeding or are thinking about breastfeeding, you should talk with your healthcare provider before taking Avastin.
Avastin and Breastfeeding: What Does the Research Say?
No studies have been done to see if Avastin passes through breast milk in humans. Because similar molecules pass through breast milk, it is possible (perhaps even likely) that Avastin will, too. The drug works by inhibiting the growth of new blood vessels, so it may cause serious problems in growing infants. In general, women are advised to avoid breastfeeding while taking it. In addition, because Avastin stays in the body for an extremely long time (several months), women are also advised to avoid breastfeeding for several months after taking it.
Talking With Your Healthcare Provider About Avastin and Breastfeeding
You should talk with your healthcare provider about Avastin and breastfeeding. Each woman's situation is different, and you and your healthcare provider understand your situation best. After considering what you want and expect, as well as your current health situation, the two of you can make a shared decision about Avastin and breastfeeding that is right for you.
