What is the proper use of a transdermal patch?

The proper use of a transdermal patch is to continuously release medication over time. Transdermal patches deliver drugs through the skin into the bloodstream, providing a consistent therapeutic effect without the peaks and troughs often associated with other routes of administration, such as oral or injectable medications. This controlled release allows for steady blood levels of the medication, which can enhance compliance and result in better management of chronic conditions.

The design of transdermal patches ensures that the medication is gradually absorbed, maintaining a steady state of drug concentration in the bloodstream, which is beneficial for conditions that require long-term treatment or consistent management. For example, patches can be used for pain relief, hormone replacement therapy, or smoking cessation, all of which benefit from this method of delivery.

Other options do not reflect the primary purpose of a transdermal patch. While the patch may not provide rapid relief compared to other forms of administration, and while it's important to rotate application sites to minimize skin irritation, the main function is the continuous release of medication into the system. Additionally, transdermal patches are specifically designed to ensure absorption into the bloodstream, rather than to avoid it.
