Effectiveness of skin icing in reducing pain associated with goserelin acetate injection.

BACKGROUND

Goserelin acetate, which is injected through a 16-gauge needle, makes some patients feel substantial, although tolerable, pain. We tried to clarify whether injection pain was reduced by icing the skin at the injection site.

METHODS

Pain associated with the injection of goserelin acetate was prospectively evaluated in 48 patients who had received an 10.8-mg goserelin injection at least once previously. In this study, the first injection was administered by usual methods, and 3 months later a second injection was administered after icing the skin at the injection site. Pain intensity was evaluated by visual analogue scale (VAS) pain score.

RESULTS

VAS pain scores for the usual injection method were 32.4 ± 21.7 mm [mean ± 2 standard deviation (SD)] and was significantly lower (16.4 ± 17.9) for the icing method (p = 0.001, paired t test). Thirty-three (68.8%), eight (16.7%), and seven (14.6%) of the 48 patients reported a decrease, no change, and increase, respectively, in VAS pain score by the icing method.

CONCLUSIONS

Icing at the injection site of goserelin acetate is a safe and effective method to reduce injection pain. This method can be easily performed in daily practice if a patient complains of pain at the injection site.
