I have been put on Clonazepam 0.5mg X 2 & Mirtazepine 30 mg for anxiety depression and restlessness.Previous to this I was on Ativan 1mg X 2 which helped me better .Can I reintroduce Ativan while withdrawing Clonazepam gradually? I do not find Clonazepam as effective as Ativan.I also have primary open angle glaucoma.
