... 5mg to assist both with sleep and also depression. She had her first dose last night and it knocked her right out. She roused about 8am and had some breakfast but went back to sleep until 11am and she was still very groggy. In the blurb above it states the 7.5 is better for assisting sleep. I am concerned about its savage affect on her, but pleased to see her sleep. I am wondering if anyone can give me some information on the use in geriatric situations please? My mother is only 50kg possibly less at present so hormones are not what they should be for two reasons - age and weight.
