Summary

This study tested whether using a ShotBlocker device, a cold needle, or both together can reduce pain and boost satisfaction during intramuscular injections. 132 adults getting vitamin B12 shots took part. Researchers measured pain on a 0-10 scale and asked about satisfaction. The goal is to find a simple, low-cost way to make injections more comfortable.

What this could mean

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

Active substance
ShotBlocker device and cold needle
What this could lead to
If effective, these simple methods could make routine injections less painful and more satisfying for patients.
What could go wrong
This is a small, completed study; results may not apply to all injection types or populations. The methods are low-risk but may not significantly reduce pain.
