Fentanyl patch prescription is safer than in the past, but physicians are still not meeting the safety requirement that patients should already have some opioid tolerance.
Fentanyl is a powerful opioid with a strength 100 times that of morphine. Previous exposure to an opioid is considered an important safety requirement for patients about to use fentanyl.
Normally, a transdermal patch delivers fentanyl continuously over 3 days. Originally available in 25-, 50-, 75- and 100-μg/h patches, a 12-μg/h patch was introduced in 2006, mainly for dose adjustment rather than initial use.
The 25-µg/h fentanyl patch is recommended for people who have already used an opioid equivalent to 60 mg of morphine a day for a week or more.
