A 65-year-old man with oesophageal cancer is having difficulties with taking regular oral morphine medications. After consulting with the oncology team, it is decided to switch him to transdermal fentanyl patches. He is currently taking 50 mg twice daily of modified-release oral morphine which has been effectively managing his pain. You prescribe a fentanyl ’25’ patch which provides the same level of pain relief. What instructions do you give the patient when starting to use the patches?
