Re : Alpha Interferon
In response to your question on alpha interferon, I have just complete
assaying interferon transfer into human milk in a mom who received 30
million units per day for a week. We are in the process of publishing this
data, but I will give you a little preview.
We then assayed alpha interferon levels in milk using a very sensitive
biological assay...and found that even after a dose of 30 million units,
none was transferred into milk. I sort of expected this result.
Interferon is a rather large molecule and is almost instantly removed from
the plasma compartment by the liver, kidney and other tissues.
Interferon use in breastfeeding moms should not be problematic.
