Don't stop taking your medicine even if you feel well. If the cause of pain goes away, talk to the doctor or nurse about slowly reducing the dose. Continue to assess pain and pain relief. Be prepared to stop reducing the dose if pain comes back. Stopping medicines too quickly can lead to side effects and the return of severe pain.
Some people worry that taking medicines on a regular schedule means taking too much medicine.
Using medicine for cancer pain on a regular schedule does not mean you won't be able to enjoy life. They can enjoy life because pain doesn't get in the way. The dose needed and the schedule vary for each medicine and each person. Duration and onset of action are different for each medicine too. Schedules can be confusing.
