What should be the site selected for applying a transdermal patch?

The site selected for applying a transdermal patch should be hairless because this ensures optimal adhesion and absorption of the medication. Hair can interfere with the adherence of the patch to the skin, potentially leading to reduced effectiveness and risk of detachment. A smooth, hairless area of skin allows for better contact between the patch and the skin surface, promoting consistent and reliable delivery of the medication into the bloodstream.

While factors like temperature and odor of the skin may play a role in comfort or minimal irritation, they are not the primary considerations when choosing an application site for transdermal patches. The main focus remains on ensuring effective delivery, which is maximized in hairless areas.
