Re:     Anthelminics

Please check my '96 book,  where you will find Vermox (mebendazole).
Mebendazole is poorly absorbed orally,  so maternal plasma levels would be
minimal.  Although it has been implicated in one case where it stopped milk
production,  I would surmise this is unusual and probably not related.

Antiminth(pyrantel) is seldom used anymore which if why I didn't include it in
my book.  Its oral absorption is minimal, so transfer to breastmilk would be
very unlikely.
