胰島素（Insulin）注射後的照護重點在於確保藥物吸收穩定。按摩注射部位會增加該區域的局部血流，導致胰島素吸收速度過快，造成血糖下降速度難以預測，增加發生醫源性低血糖的風險。正確的衛教應包含：輪替注射部位（預防脂肪增生）、注射前酒精消毒、胰島素開封後的保存原則以及注射後僅需輕壓止血，絕對禁止按摩。
Massaging the injection site after insulin administration is contraindicated because it increases local blood flow, leading to unpredictable and rapid drug absorption. This can cause sudden hypoglycemia, indicating a need for further instruction. Proper technique involves rotating sites, cleaning with alcohol, and applying gentle pressure without rubbing.
