Carfentanyl or Carfentanil? Understanding the Two Spellings

Carfentanil (can also be spelt carfentanyl) is an extremely potent synthetic opioid analogue of fentanyl.

You may see the synthetic opioid referred to as both carfentanil and carfentanyl. While these terms are often used interchangeably, carfentanil is the internationally recognised and scientifically accepted spelling used in medical, toxicology, forensic, and regulatory literature.

The spelling carfentanyl is a common alternative spelling that appears in some media reports, online articles, drug testing resources, and public discussions. This variation likely arises because many powerful synthetic opioids, such as fentanyl and sufentanil, end with the suffix "-fentanyl", leading some writers to assume that carfentanil follows the same naming convention.

When searching for information online, it is useful to be aware of both spellings, as individuals may use either term when researching drug testing, overdose risks, toxicology reports, or substance misuse. 

For clarity and consistency, healthcare professionals, laboratories, law enforcement agencies, and scientific publications more commonly use the spelling carfentanil, while acknowledging that carfentanyl is a recognised alternative spelling encountered by the public.
