Are Fentanyl duragesic patches effective if placed under tongue?

Fentanyl Duragesic patches are designed for transdermal delivery, meaning they release the medication through the skin into the bloodstream over time. Placing the patch under the tongue is not recommended, as it can lead to improper absorption and may result in dangerous side effects or overdose. It’s essential to use the patch as directed by a healthcare provider for safe and effective pain management.
