Arnetta:  Was this mother symptomatic?  Was her family?  It's interesting
how they would wait five months in order not to give it to her during the
pregnancy, (it's mainly contraindicated during the first trimester due to
teratogenicity in animals), but then have to give it to her the day she
delivers.  The usual recommended dose for pinworm is one tablet, once.
The 3 day treatment is for whipworm, roundworm and hookworm.  What
exactly is this doctor treating?  In view of Dr. Hale's post alluding to
a case of reduced milk supply, I would consider postponing the other two
tablets unless she really has one of the other infections and is
symptomatic.  The guiding principles of medication use during lactation
have to include not giving a potentially harmful medication (in this
case, mainly harmful to lactation not the baby) if not necessary.  If the
infection was not so serious as to mandate treatment during pregnancy, it
probably can wait a few more weeks or months.  Good luck, Alicia.
