Can I take tamiflu (oseltamivir) while breastfeeding?

Yes. Studies show babies receive 1/2% of the mothers dose which is unlikely to produce significant levels in an infant. The CDC has recommended its use in breastfeeding mothers. See "medications and mothers milk";hale, 2010.
No. It is generally not recommended for pregnant or nursing mothers to take tamiflu, (oseltamivir) as its effects on breast-feeding babies are not known. Because of this, you should weigh the benefits of taking a medicine that will only decrease your flu symptoms by one or two days versus the unknown effects on your nursing infant.
