If a pancreatic cancer patient is experiencing pain, the choice of pain medication can be based on the specific severity of the pain. For mild pain, mild pain relievers such as ibuprofen sustained-release capsules can be chosen initially. For moderate pain, pain relievers like tramadol can be used. If the daily dosage of tramadol exceeds eight tablets, which is two tablets each time, taken every six hours, and if the pain relief is still inadequate after 24 hours, then it might be appropriate to switch to opioid painkillers such as hydromorphone sustained-release tablets, morphine sustained-release tablets, or morphine.
