who made fentanyl

The powerful opioid fentanyl was first synthesized by Belgian chemist Dr. Paul Janssen and his team at Janssen Pharmaceutica in 1959–1960 as a new medical painkiller, not as an illegal street drug.

Quick Scoop: Who made fentanyl?

• Fentanyl was created in the late 1950s by Dr. Paul Janssen, a pharmaceutical researcher in Belgium.

• His company, Janssen Pharmaceutica, patented and developed it as a very strong pain reliever for surgery and severe pain.

• It was introduced into medical practice in the 1960s (for example, as the anesthetic “Sublimaze”) and later became one of the most widely used synthetic opioids in hospitals.

Why was fentanyl made in the first place?

• Doctors at the time needed a fast-acting, powerful painkiller that worked better than morphine during complex operations like open‑heart surgery.

• Janssen’s goal was to design a more potent narcotic pain reliever, and fentanyl turned out to be roughly 50–100 times stronger than morphine, with properties that made it attractive for anesthesia.

From medicine to crisis

• For decades, fentanyl was mainly a hospital drug used by anesthesiologists and pain specialists.

• In recent years, illegally made fentanyl (not produced by Janssen’s company) has spread in street drugs, driving a major overdose crisis in the United States and other countries.

In short: A legitimate pharmaceutical chemist, Dr. Paul Janssen, invented fentanyl for medical use — but today, much of the fentanyl causing harm is illicitly manufactured copies and analogs, not the original regulated medicine.
