Re: How long is Azithromycin detectable in breast milk?
Welcome to the forum and congratulations on the baby to come!
For questions about medications and medication safety, I would contact the Infant Risk center: http://www.infantrisk.com. They should be able to answer your questions about safety and persistance of the antibiotic. I'm pretty sure they will give you the same answer as your doctor did.
I think it's great that you're taking the probiotics. I really would not worry much about gut imbalances or thrush. Taking an antibiotic only raises your chances of those problems. It's not a guarantee, right? Most people who take antibiotics have no problems. And while I understand your desire to protect your baby from the antibiotics, remember that your milk is way more than just nutrition. It also contains a ton of immunological support factors, including prebiotics that help foster the growth of a healthy gut microbiota. This is an interesting article about what breastmilk has to offer: https://pubs.acs.org/cen/coverstory/86/8639cover.html
Personally, if I were choosing between breastmilk carrying some antibiotic residues or antibiotic-free formula, I would choose breastmilk almost every time. At least if the antibiotic involved were azithromycin, which I took twice while nursing, and never had any negative outcomes from it for either me or my kids.
