Because there haven't been any studies done on Botox and breastfeeding, the manufacturer recommends that the drug not be used in nursing women. The effects Botox may have on an infant are unclear, but it is unlikely to pass through breast milk in amounts significant enough to cause problems. If you are taking Botox and breastfeeding is something you are considering, discuss the issue with your healthcare provider.
Botox and Breastfeeding: An Overview
It is not known if Botox® (onabotulinumtoxinA, previously known as botulinum toxin type A) passes through breast milk. Allergan Pharmaceuticals, the manufacturer of the drug, recommends that Botox be used with caution in breastfeeding women. Therefore, if you are breastfeeding or planning to start, you should talk with your healthcare provider before taking Botox.
Botox and Breastfeeding: What Does the Research Say?
Botox has not been studied in any breastfeeding women, and it is not known if the drug passes through breast milk or if it poses any risk to nursing infants. However, Botox is unlikely to pass through breast milk, since only a tiny amount of the drug reaches the bloodstream (which it must do in order to pass through breast milk).
Talking With Your Healthcare Provider About Botox and Breastfeeding
You should talk with your healthcare provider about Botox 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 Botox and breastfeeding that is right for you.
