Painkiller showdown: can cancer patients ditch paracetamol while on opioids?
NCT ID NCT05088876
First seen Jun 24, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study looked at whether cancer patients already taking strong opioids (like morphine) still need paracetamol for pain control. Researchers planned to have 7 participants stop their regular paracetamol in a blinded way, but the trial was terminated early. The goal was to see if pain levels stayed the same without paracetamol.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
Active substance
Paracetamol
What this could lead to
If successful, it could show that paracetamol is unnecessary for some cancer patients already on strong opioids, simplifying their medication.
What could go wrong
The trial was terminated early with only 7 participants, so results are very limited and not reliable. It may not apply to all patients.
