New combo pain treatment could ease suffering for kids after bone marrow transplant

This study looks at whether adding methadone to the usual morphine pain medicine can better control severe mouth pain in children aged 6 to 18 who are getting a stem cell transplant for conditions like leukemia or aplastic anemia. The mouth pain is a common side effect of the chemotherapy given before transplant. The goal is to see if the combination reduces pain scores and the total amount of pain medicine needed, helping kids feel better and possibly eat sooner.
