How should a medical assistant apply a transdermal patch?

Applying a transdermal patch directly to clean, dry skin is crucial for maintaining its effectiveness. The skin is the intended absorption site for the medication, and direct contact ensures that the therapeutic agents in the patch can penetrate through the skin layers and enter the bloodstream effectively. This method optimizes the delivery and absorption of the medication, avoiding any barriers that could hinder its intended purpose.

In contrast, cutting the patch could alter its delivery system, potentially leading to uneven dosing and reduced efficacy. Placing the patch on clothing would prevent direct contact with the skin, making it ineffective in delivering medication. Additionally, applying the patch over an existing bandage might interfere with absorption and could also lead to a risk of irritation or skin reaction due to the two adhesive materials interacting. Therefore, directly applying the patch to the skin is the best practice for ensuring it works as intended.
