The best way is to talk to the physician, or nurse in the doctor’s office before you leave the office. In the doctor’s office, if you can’t reach the doctor, you MUST speak to the nurse, because the others don’t have medical training. The receptionist may not pick up the nuances of the patient’s communication or understand the implications of the question or answer. If you work with a Home Health Agency, you could call/ask the nurse there. If you’re in the hospital, these questions should be asked of the doctor or nurse before you leave the hospital. Also, if you receive new prescriptions for medications upon hospital release, you should pick them up BEFORE going home.
