Thanks for the information.
Well, first of all we need to consider the fact that despite your mother having been placed on trazadone , lorazepam and prozac , for quite a long time , has not showed any improvement in her Anxiety , which makes us believe that your mother has deveoped resistance against these drugs , as a result of which these drugs have become ineffective in controlling her anxiety .
further to her Anxiety disorder , she probably also has developed Senile ( age related ) Dementia , in which the person becomes agitated , anxious , and this is adding futher to her anxiety.
So i would suggest that you consult her Psychiatrist , and ask her to review her psychiatry drugs , as the drugs have become ineffective due to the body developing resistance against these drugs .
Also, discuss with the psychiatrist ,use of anti depressants belonging to different group such as Venlafaxine and milnacipran , which belong to SNRI anti depressant group , different from prozac ( ssri anti depressant ) and trazadone ( atypical anti depressant ), plus venlafaxine and milnacipran are quite effective in controlling Anxiety . So, out of the two , the doctor may choose only 1 anti depressant and along with this drug , the anti anxiety drug lorazepam is to be continued .Alternative anti anxiety drugs to lorazepam , are - clonazepam , etizolam , buspirone .Any one of these can be used if lorazepam becomes ineffctive.
I wish your mother best of health.
