My husband has dementia and went into a residential home for 3 months to give me respite. His medication was changed to Trazadone and since then he has lost over 2 stone and now weighs 8st 4lb. I am so worried and have voiced my concern to the staff. I spoke to the doctor as weight loss can be a side effect of this drug but he said he didn't think it was due to the Trazadone as he is only on 50mg. I feel desperate as my husband looks emaciated. Do I have any authority to ask for him to be taken off the drug?
