i have a lady who is taking vicodin for pain. i've noticed that after taking vicodin, she becomes more confused, more crying, unable to remember where she is, but still complaining of sever pain. her daughter came to visit her and told me that she also noticed that she becomes more confused after taking this pain medicine. so what is the best way to deal with this? change to different pain medicine or decrease the frequency of pain medicine? at first doc increased the frequency of vicodin due to patient still complaining of severe pain then after telling him about increased confusion, he increased the number of tablets from one to two tablets. so i'm not sure which way is the best way to deal with this?
