A man comes in with a prescription for fentanyl patches. He tells you that they are for his mother who has terminal cancer, and expresses relief that she has been moved from morphine tablets onto a form of pain relief that doesn’t necessitate swallowing. He asks if he can just replace the patch at the stated interval, discarding the used one in the bin, or if there is anything in particular he needs to know.
How would you advise this man?
