The FDA is investigating reports of deaths and other serious side effects from the use of the fentanyl transdermal system as well as overdoses.
Exposing the patch to heat can increase the amount of fentanyl released and may lead to an overdose. Some patches may cause burns of the skin if worn during an MRI (magnetic resonance imaging) scan. Patients should tell their health-care professional that they are using a medication patch prior to receiving an MRI scan.
