Why is rotating subcutaneous injection sites important?

• A. Rotating sites helps prevent tissue damage and lipodystrophy.
• B. Rotating sites has no benefit.
• C. Rotating sites increases infection risk.
• D. Rotating sites reduces absorption.

Answer: (B)

Rotating subcutaneous injection sites is important to protect the tissue and keep absorption reliable. Repeated injections in the same small area can cause tissue damage and lipodystrophy, where the fat under the skin becomes scarred, hardened, or thinned. When that happens, the medication may be absorbed unpredictably, and injections can become more painful or develop lumps. By using different approved sites and giving each area time to recover, you reduce the risk of tissue changes and help ensure a more consistent, predictable absorption of the dose.
