Why do you avoid harden or fatty site when injecting subcutaneous?

Avoiding hardened or fatty sites when injecting subcutaneously is crucial because these areas can affect the absorption rate of the medication, leading to inconsistent dosing and potentially reducing efficacy. Injecting into hardened tissue can also cause discomfort and increase the risk of complications, such as infection or tissue damage. Additionally, these sites may have altered blood flow, which can further impair absorption. Therefore, selecting healthy, pliable tissue helps ensure optimal medication delivery.
