breakthrough pain
"I was essentially mis-prescribed Actiq when I should have been getting fentanyl patches for my cancer pain.  This caused problems with both bolus dosing (transient overdosage) and build-up of opioid tolerance with the Actiq that have not been nearly as great a problem with fentanyl patches.



Other patients may have different experiences; however for chronic cancer pain, the patches might be considered before use of Actiq."
