Why is it important to wear gloves when applying topical medication to a patient?

Wearing gloves when applying topical medication is important primarily to stop absorption of the medication by the caregiver's skin. When a caregiver applies a medication directly to a patient's skin, there is a risk that some of the active ingredients may be absorbed through the caregiver's skin as well. This could lead to unintended side effects or systemic effects on the caregiver, especially if the medication has potent active ingredients or if applied repeatedly. The use of gloves creates a barrier that prevents this absorption, thus protecting the caregiver while ensuring that the medication is delivered effectively to the patient.

In addition, while there are other important considerations such as preventing infections, allergies, and ease of application, the primary focus here is on protecting the caregiver from exposure to the medication itself, which may have specific actions that are not desirable for someone who is not the intended recipient.
