My mother has stage 7a mixed dementia. I have Lasting Power of Attorney, Health & Welfare. She has something of an occasional history of aggression with staff, last mentioned to me in late 2017. She is now 91, is barely eating and broke her pelvis in early November, for which the GP has prescribed a low-dose opiate patch. I had a call from her home today to say that her psychiatrist visited this morning (I don't know if this was routine or requested, but I was not informed of an impending visit). The nurse from the home told me that the psychiatrist changed my mother's medication (she was on Sertraline, which I previously approved) and has additionally prescribed diazepam and lorazepam. I questioned why, and was told that she is sometimes aggressive when being given personal care. This is the first I've heard of this. She sleeps almost all the time and has become very weak and I'm concerned about why this nurse is telling me that they suddenly need to administer what is effectively a chemical cosh to be able to handle her, when she has been fine for more than a year, as far as I'm aware. (I visit at least twice a week and always ask how she's been). I'm also concerned that she may be aggressive (if she really is) because they're handling her badly when she's in pain. I have previously told the home that they are not to give her tranquillisers without asking me first. They did so twice in 2017. The GP didn't prescribe them again after that, so that they couldn't use them. I was also told the the psychiatrist sanctioned covert administration, which I though needed a case conference. I've spoken to the GP and no aggression issues have been mentioned to them for a long time. I don't want her given tranquillisers and it was her explicit wish when she was capable that I shouldn't allow it. I'm afraid this is a case of staff using drugs to make her compliant. She's at the stage where she said (verbally) she wanted treatment withdrawn (including antibiotics) so that she could be allowed to die. I'm happy for painkillers to be given, but really unhappy about tranquillizers. I'm also worried about the effect of tranquillisers on top of the opiate patch, which I'm worried the psychiatrist may not have been aware of. What can I do to prevent the drugs being given? I'm trying not to get into conflict with the home, but Mum has to come first
