NCT ID NCT02390505
First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study tested whether taking vitamin C before and after planned upper limb surgery could prevent complex regional pain syndrome (CRPS), a chronic pain condition. Nearly 1,000 adults participated, receiving either vitamin C or a placebo. The goal was to see if vitamin C reduces CRPS occurrence at 6 months after surgery.

Vitamin C
What this could lead to
If it works, this could provide a simple, low-cost way to prevent a painful chronic condition after upper limb surgery.
What could go wrong
The trial is completed but results are not yet widely known. Vitamin C may not reduce CRPS risk, and individual factors like allergies or hemochromatosis could limit its use.
