There is one case study in the literature about gray or black milk produced by a mother who had minocycline therapy. I had a daughter on this drug for many months in tx of acne. Ask the mother if she has a hx of adolescent acne with tx with this antibiotic. It would be prudent to do the standard workups, but this may just be stained fluids which will flush once milk really comes in.
