Why is it important to rotate application sites for patches?

Rotating application sites for patches is essential primarily to prevent skin irritation. When a patch is applied to the same area repeatedly, it can lead to localized skin issues, such as rashes, redness, or breakdown of the skin barrier. By changing the site of application, the skin is given the opportunity to heal and recover, reducing the likelihood of adverse reactions and ensuring that the patch can adhere properly and function effectively in the future.

Although optimizing medication efficacy, absorption rates, and managing side effects are important aspects in medication administration, these factors are less directly influenced by the rotation of application sites compared to the prevention of skin irritation. Therefore, the main reason for this practice focuses on maintaining skin integrity and comfort for the patient.
