I've been on 75mg of mirtazapine for 7 months , primarily for anxiety and insomnia. is this high dose normal? how would you reccommend cutting back?

High dose.: Does seem like a large dose, but may be appropriate for you. Personally i would prefer to see you on a "cocktail" of a few meds at lower doses. As far as tapering could reduce by 1 tab every week . Would not do this without discussing with your doc and having a plan for addressing symptoms if they occur.

Almost, but why?: The dosage for mirtazepine may include and , rarely, exceed 90 mg. Dosage must reflect how your body metabolizes the drug. The important question is" how are you feeling?" if you have had very good or excellent relief of anxiety, and if you have learned anxiety management skills or remedied the situation for which you started the medication, then slow reduction is possible over months.
