Dany: Cefzil is cefaprozil, a cephalosporin. I don't have anything handy showing any advantage of it over other cephalosporins, but I'm sure that there are other antibiotics which cover the bacteria she's infected with. In my experience, doctors often prescribe a medication they're comfortable with or have samples of in the office, so it's not necessarily the only drug that will work. When it comes to breastfeeding, I believe it's best to use an effective medication we know is compatible rather than wondering about some new drug and its possible effects. Alicia. [log in to unmask]
