Why is it essential to rotate injection sites for subcutaneous injections?

Rotating injection sites for subcutaneous injections is essential primarily because it minimizes tissue damage and irritation. When injections are administered in the same spot repeatedly, it can lead to a condition known as lipodystrophy, which is the abnormal distribution or deterioration of fat in the injected area. This can cause discomfort, scarring, and reduced efficacy of subsequent injections, as the localized tissue can become less responsive to the medication over time. By rotating sites, you help ensure that the tissue remains healthy, reducing the risk of irritation and potential complications, thus providing a more comfortable experience for the patient. This practice also promotes effective medication absorption by preventing the formation of hardened tissue that can interfere with the delivery of the drug.
