A friend saw a doctor who wrote a prescription for her for Amoxicillin a few months ago. Last week she saw another doctor for a consultation about an unrelated problem and the doctor asked her why she took Amoxicillin. She never told the doctor about her visit with the other doctor or about the Amoxicillin prescription so how did this second doctor find out about the Amoxicillin use as it is not a controlled substance like narcotics? Now she is wondering if the pharmacy is sharing her prescription use, who they are sharing it with, and how they are sharing it as she is a privacy advocate.
