Hello all, My dad goes from being perfectly lucid and calm one day, to incoherent and maniacal the next. This is all very new to us so it's frightening to see, particularly for my 90-year old Mum who has known Dad for over eighty years and cannot understand why his physical and mental strength are deserting him. This morning, he was so agitated, we called our GP to ask if there was something he could be given to calm him. As a family, we would have preferred not to go down this route but Dad was SO agitated, we were concerned he may harm himself, or Mum, by lashing out. (He's in bed, by the way). Long story short, the doctor has reluctantly prescribed a mild sedative called PROMETHAZIN HYDROCHLORIDE 25mg, which Dad has to take for seven days. Does anyone have experience with this medication? Thanks in advance for any feedback.
