Greetings all! My domestic partner is 71 yrs old and been on morphine for about two yrs now. She had a mini stroke around thre yrs ago and diagnosed with PN after that. They tried all kinds of pain meds, everything edit her made her deathly sick or she had bad reactions. Morphine is only thing that helps the pain and she can tolerate. She's also been taking topomax for her migraine. Today neurologist took her off topomax because of memory loss and thinks pain doc should cut down on her morphine to get her memory loss under control. Tests show it's NOT dementia but due to meds. Anyone know of a good sub for morphine? She's on 120mg a day. Is that considered a lot? We go back to pain doc in a few days.
