Summary

This trial is testing a new topical pain medication against a low-dose capsaicin control to see if it is more effective and safe in treating moderate to severe post-surgical neuropathic pain.

Who is the study for?
Adults aged 18+ with moderate to severe nerve pain following surgery, who can apply the treatment on intact skin and agree to use birth control if applicable. Excluded are those with confounding conditions like deep tissue pain, planned painful procedures during the trial, or surgeries related to cancer.
What is being tested?
The trial is testing Qutenza (8% capsaicin) against a low-dose capsaicin (0.04%) for treating postsurgical neuropathic pain. Participants will be randomly assigned to either group in a double-blind manner, meaning neither they nor the researchers know who gets which treatment.
What are the potential side effects?
Potential side effects may include local skin reactions such as irritation, redness, burning sensation at the application site; these are more common due to capsaicin's nature of causing a warming or tingling feeling.
