Brief Answer: Unfortunate Detailed Answer: Hello, Thanks for choosing health care magic for posting your query. I have gone through your question in detail and I can understand what you are going through. What you have experienced with mirtazapine is a rare phenomenon. IN elderly people mirtazapine in low dosage is a good medicine for sleep and I generally prescribe it in the dosage of 7.5mg. Its an effective drug in this dosage and I have never notied such a problem. There could be three possibilities: 1) Mirtazapine could have been prescribed in a higher dosage leading to complications. 2) Some other drug was prescribed instead. 3) She had an reaction to the medicine, which otherwise could not have been predicted. The best thing would be to keep your mother off drug at present until she recovers completely. There after she may be started on Tab Clonazepam 0.25 mg at night for sleep. Hope I am able to answer your concerns. If you have any further query, I would be glad to help you. If not, you may close the discussion and if possible you may rate the answer for me, so that I get a good feedback.
