First I need to know where you were injected and how much Botox was used for your treatment. Botox injected cosmetically is very unlikely to get into your blood stream and therefore to your breast milk. Also the Botox molecule is quite large and unlikely to get absorbed into breast milk even if it was absorbed into your blood stream. Therefore, the chances of any harm to your baby is EXTREMELY LOW. Even so, I would not recommend that you continue with your Botox injections while you are breastfeeding.
