Educational Pearls

  • Fentanyl patches may be abused in many ways, including changing the patches more frequently, chewing them, extracting the fentanyl in a tea, and administering them rectally.
  • Fentanyl is very lipophilic and has a fast onset, but it has a very low bioavailability when given enterally, because it does not survive the stomach and 1st pass metabolism. It can be given IV, intranasal, through the buccal mucosa, or transdermal.
  • When patients present with fentanyl overdose due to ingestion of a patch, it is more important to find out how long the patient had the patch in their mouth, since that is the principal form of absorption.
