But why take that unnecessary risk? Remember the recent Choosing Wisely campaign? Number two on the list for family physicians was avoiding antibiotics for mild-to-moderate sinusitis less than 7 days duration . When do you need antibiotics? AAAAI & AAFP came out w/similar recommendations in consensus w/ Consumer Reports Health . As I teach my residents (and patients), there are no free lunches ( especially at the School of Medicine since pharmaceutical companies signed off on the revised guidelines regarding interactions w/healthcare professionals ) as every medication is actually a double-edged sword. So choose wisely!
