Yes, thank you Kazbern. Not only did my GI and OBGYN approve Entocort while breastfeeding, but it was deemed safe by Dr. Hale- a doctor who has performed extensive research on the effects of medication in mothers' milk, mainly because, like I said, it is MOSTLY absorbed in the small intestine.
Another article: http://www.ncbi.nlm.nih.gov/pubmed/17825891 shows "Maintenance treatment with inhaled budesonide (200 or 400 microg twice daily) in asthmatic nursing women results in negligible systemic exposure to budesonide in breast-fed infants."
And another: http://toxnet.nlm.nih.gov/cgi-bin/sis/search/f?./temp/~s7qUqR:1
"The amounts of inhaled budesonide
excreted into breastmilk are minute and infant exposure is negligible. Reviewers
and an expert panel consider inhaled corticosteroids acceptable to use during
breastfeeding.[1][2][3] When taken by mouth, budesonide is only about 9% bioavailable;
bioavailability in the infant is likely to be similarly low for any budesonide that enters the breastmilk."
The "Name Brand" Entocort has a warning for breastfeeding mothers, but so does Advil and GasEx, etc. I have no issue with any mother who wishes to abstain from medications while pregnant or nursing, but information from 2008 is not necessarily "up to date" with all the ever-changing research going on today.
In the end, you have to do what is right for you and your baby. Most women flare after childbirth and will need to take something. If I didn't go on some additional meds I would have been useless as a mother and wife. For me, breastfeeding was important, so I found medications that were compatible with nursing. I nursed for a year on Humira and Entocort, and my son has always been very healthy. Good luck!
