Cultural Tip
In Italy patients often use the formal 'Lei' when addressing a doctor, e.g., 'Quali effetti collaterali ha il farmaco, dottore?'. The phrase above is informal and suitable for friends, family, or when the doctor invites a more relaxed tone. Also, Italians appreciate clear, concise questions about health, so avoid overly long sentences.
