There aren't any data on Botox use during lactation, but the procedure is currently considered safe. Though Botox is derived from a toxin that causes life-threatening botulism when consumed in food, it's not detectable in your bloodstream after injections. Therefore it is unlikely to pass through your breast milk, according to the National Center for Biotechnology Information. Even in instances when breastfeeding parents ingest and contract botulism, babies appear to be protected. It's best to wait a few hours after an injection before breastfeeding, though, to be safe. Only get injections by a licensed medical professional to be safe.
