Generally no but it depends on the setting (eg outside a hospital or Pharmacy) but even at that I have seen it used in a hospital setting. There was a gentleman in scrubs with a surgical cap. I looked at his hospital name tag and it said Dr. Fred Smith, DPharm. I think that is a wise course to identify yourself by saying that you are Dr. Fred Smith your Pharmacist so there is no question. That said I have seen a number of Medical doctors angry on Social Media about Nurse Practitioners and others earning doctorates and that is not even taking into consideration the "Dr. Title". While there may be some legit concerns there are also aspects of turf war. Some MDs/DOs feel other specialities are edging into their territory (and there is some truth in it as various specialties demand more privileges or increased scope of practice and insurance companies see them as cheaper alternatives).
