injection sites

Injection sites are specific areas on the body where medications or vaccines are administered beneath the skin or into muscle tissue. Common sites include the upper arm (deltoid muscle), thigh (vastus lateralis), abdomen, and buttocks. Proper site selection ensures effective absorption and minimizes discomfort or complications. Healthcare providers choose these sites based on factors like the type of medication, patient age, and body size. Proper technique and site selection are essential for safety and effectiveness, reducing risks like nerve injury or tissue damage.
