Spinosad topical Breastfeeding Warnings

This drug is not systemically absorbed after topical use; it should not be present in human milk.

The topical suspension contains benzyl alcohol, which may be systemically absorbed through the skin; the amount excreted into human milk with use of this drug is unknown.

Caution is recommended.

Excreted into human milk: No (active component); Yes (benzyl alcohol)

-High amounts of benzyl alcohol are potentially harmful to neonates; it is unlikely that levels this high reach breast milk.
-Lactating women may choose to pump and discard breast milk for 8 hours (5 half-lives of benzyl alcohol) after use to avoid infant ingestion of benzyl alcohol.
