Why would you avoid and injection site that is hardened or fatty?

Avoiding an injection site that is hardened or fatty is important because these conditions can impede the absorption of the medication, leading to reduced effectiveness. Hardened tissue may indicate previous injections that caused scarring, which can result in pain or discomfort during the injection. Additionally, injecting into fatty tissue can alter the pharmacokinetics of the drug, potentially causing unpredictable effects. Selecting a healthy, pliable site ensures better absorption and minimizes complications.
