Summary

This study tests whether adding methocarbamol, a muscle relaxant, to standard pain relief can reduce the need for opioids after ventral or inguinal hernia repair. Adults undergoing surgery are randomly assigned to receive either standard opioids, methocarbamol alone, or both. The study tracks how many people need extra opioid prescriptions and their total opioid use over 30 days after surgery.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
Methocarbamol
What this could lead to
If it works, this could point toward a way to reduce opioid use after hernia surgery, lowering the risk of addiction and side effects.
What could go wrong
This is a small pilot study, so results may not be conclusive. Methocarbamol may not reduce pain or opioid needs, and could cause side effects like drowsiness.
