My mother has been on Remeron for four years. She started for depression and received the prescription from a psychiatrist. Our family raised questions about the drug with her psychiatrist after she began to have rage issues and became very disagreeable. My mother and her psychiatrist insisted the was doing fine on the medicine. Since that time things have only escalated. She now gets Remeron from her family doctor. She has become more and more enraged, throwing things and has gotten physical with my father, her husband of 46 years. He has been living with my sister for the past month because of her extreme behavior. She is estranged from all family, (except one son) and friends because of her behavior. We are very concerned for her. She has denied still taking Remeron but we did not believe this. And has recently found she has a newly filled prescription for 30mg. I have called her doctor and relayed all of her extreme behavior. Just hope and pray he does not continue to prescribe this drug for her. It has torn my entire family apart. Any suggestions would be welcomed.
