My doctor had prescribed Clonazepam 0.5 mg X 2 daily and Mirtazapine 30 mg at bed time daily for 60 days, Which has helped me alot, what is the usual safe weaning off period for these drugs .Or is it decided by decreasing the dose gradually or by introducing new medicines.Please inform me. I also have Primary open angle glaucoma and these medicines have not interfered with my eye medicine , The only side effects I have felt were severe constipation and pain in my left thigh some times when walking or when arising from bed.
