This pediatrician seems to relish telling this mother not to
breastfeed. The drugs mentioned should be of no concern. Ondansetron
(Zofran) has peak levels in maternal serum of 20-30 nanograms/ml.
This is boo all. And the oral bioavailability is relatively low at
60%. Don't worry. Keep nursing.
You know, the mother does not have to listen to the pediatrician. Why
not listen to the neurosurgeon or anaesthetist? Or her own heart?
