Influenza infection may lead to serious complications in the postpartum period, therefore,
oseltamivir treatment in these patients and their breastfed infants is of great importance.
However, the pharmacokinetics of oseltamivir in postpartum lactating women with acute
influenza infection, and the consequent infant exposure to oseltamivir are still unknown,
and these data would help in assessing risk and the need for dose adjustment in breastfed
infants.
