Yes, it’s generally considered safe to take Tamiflu, also known as oseltamivir, while breastfeeding. This is based on research indicating 1 that only minimal amounts of the drug are transferred into breast milk.

In terms of numbers, the levels of oseltamivir found in milk are quite low, specifically around 39 ng/mL. To put that into perspective, this amount is so minor that an infant would receive only approximately 0.5% of the mother's dose. 

Additionally, the Centers for Disease Control and Prevention 2 (CDC) consider oseltamivir safe for use by breastfeeding mothers. Despite this reassurance, as with any medication, it’s always a good idea to discuss the use of Tamiflu with your healthcare provider to ensure it’s the right choice for your specific situation.
