The Effect of ShotBlocker on Injection Pain

ShotBlocker (Bionix, Toledo, OH) is one of the methods that can be used to reduce pain caused by IM injections. This small, flat, U-shaped plastic device used by holding it on the skin surface during injection did not have any side effects \[5\]. ShotBlocker has a surface of 2 mm thick with rounded nubs to stimulate the skin (Figure 1). The surface of the plastic device is placed on the skin just before the injection; there is a hole in the center where the injection is administered \[6\]. The rounded nubs on the surface of the plastic device do not damage the skin, these rounded nubs that create a slight pressure provide a warning for the Gate Control Theory \[7\]
