What is this pain medication? It is a patch worn on the lower stomach?
In addition to the lido patch some doctors will also prescribe a fentanyl patch. It is odd for her to apply it to her pubic area though for either patch. There are more patches like morphine too. That is a bit significant though because morphine patches are generally given to severly uncontrolled pain. However, fentanyl is in relation to morphine and either of those two can have side affects and can even have an overdose affect on her that can lead to death in worse case scenarios. In your question though…it can make her strange and highly addictive. You could ask her what patch they are but be sensitive on your other issues because people generally will get highly defensive. I would mention it to her doctors office or family members that too can address it with her doctor. They are the ones that will have to wean her off of it and try another method. She cannot just quit cold because there are horrible affects to that as well. Good Luck and know that you are a wonderful friend for c
