My Brother In Law Has Pancreatic Cancer. He Has Had

My brother in law has pancreatic cancer. he has had the second bag of chemo but asked to go onto morphine. He has been on tramadol 50mg x 8 tbs a day and we wondered if he could have had an increase in the dosage of the tramadol as he asked me if this was possible as hadnt wanted to go onto morphine so soon. He is under the care of the JCUH specialist. It is only as I wanted to be able to answer his question when we speak tomorrow. He will only change medication under supervision of the specialist of course. thank you very much for your specialist knowledge.
