This is for My father of Age 75 ,weight 43 kg and height 177 cm. He is under treatment for dementia related issues as described below. We are consulting with Neurologist and he was taking the tablet Donep of 10 mg for the last one year. Now he added one more medicine since there is no improvement and stills showing more angry and aggressive behavior. The medicine name is QUETIAPINE 25 mg. One tablet night after food When am browsing in internet it is not approved to older people with dementia related issues. It may cause serious issues. Is that correct? Or shall we continue with the medicine?
