Phone your Dad's GP. My late husband was in a CH and whenever the GP was called out I was informed and made sure I was there to speak to him. I could also phone the surgery at any time to express my worries. My Husband was on Zopiclone as a PRN for when he had trouble sleeping-but only when he was awake for days/nights on end.

Years ago Pete was on Mirtrazapine but with hindsight I don't think that helped him much. Shrugged shoulders are not helpful

Take care

Lyn T-I hope you can get some answers

 

This all sounds ridiculous. Dementia is likely to lower mood so how does Mirtazapine change anything? All this medication ever gave me when I was depressed was dreadful night sweats. Our G P advises that Zopiclone is only to be used for a week or so as it is addictive. Ask to meet the G P and seek an explanation about why this medication has been prescribed without any reference to you.
