No, phenacetin and paracetamol (also known as acetaminophen in the United States and Canada) are different drugs, although they share some similarities. Both drugs were historically used for pain relief and fever reduction, phenacetin’s safety issues led to its discontinuation in many countries, while paracetamol remains a commonly used and widely available medication.
