Suicide by Duragesic transdermal fentanyl patch toxicity

Abstract

A study has shown that a used patch, depending on size, will still contain 0.7 to 8.4 mg or 28% to 84% of fentanyl [2]. [...]disposal is paramount as even a used patch will still contain toxic levels of fentanyl and should be flushed down the toilet after use to prevent accidental exposure. [...]proper disposal of used patches and screening of high-risk individuals are critical with fentanyl treatment.
