A topical patch is a small adhesive patch that is applied directly to the skin. It delivers medication through the skin and into the bloodstream, providing a controlled release of the drug over time. This method is often used for pain relief, hormone therapy, or to manage certain medical conditions. Topical patches are convenient and easy to use, as they eliminate the need for oral medications or injections. Common examples include patches for nicotine cessation and pain management, such as those containing fentanyl or lidocaine. They are typically worn for a specific duration, depending on the medication and treatment plan.
