Drug safety
-
Fentanyl buccal tablet (FBT), a potent opioid, was approved in Canada in 2013 for breakthrough pain in opioid-tolerant adult cancer patients. Additional risk minimization measures (aRMMs), consisting of communications to patients and healthcare providers (HCPs), were implemented from November 2014 through September 2015. ⋯ The aRMMs as measured by the prescriber KAU were effective for most key safety messages; however, not all key messages of the aRMMs were stringently followed in routine practice.
