You can use boric acid while breastfeeding, but there are some important points to consider.
Let's break this down: boric acid is used as a suppository for treating certain types of vaginal infections. A small amount of boric acid (about 6%) does get absorbed into your system, so it's likely a small amount will make its way into your breast milk.
When it comes to using boric acid for a short period (fewer than seven days), the risk to a breastfed infant is generally low. But if the treatment goes beyond that, especially for exclusively breastfed babies, the risk could potentially increase 1 . That's because of the long half-life of boric acid, which is around 20 hours.
Just remember to keep an eye on your little one for any potential side effects, like changes in mental status, vomiting or diarrhea, jaundice or rash. And before you start any new medication, it's a smart idea to have a chat with your healthcare provider, just to make sure you're on the right track.
