Mirtazapine Anxiety Reviews

Tue, 21 Sep 2010

The above comment is too stupid, I actually LOLed at you Pete... lol you gave it 2 days and your complaining about the side-effects? and on 15 mgs? LMAO!!! It takes couple weeks at least to cope with the side-effects; just like many other drug. What is this; your first ever prescription medication? Your comment is misleading for others and very stupid.

I was on 45 mgs Mirtazipine for 2 years and even when I stopped abruptly I experienced zero to none of the withdrawal symptoms people are talking about... (but that might just be me, everyone is diff, however I never heard anyone dying from taking this medication. Unless combined with Benzos, pain killers and alcohol at the same time as it will def in that case cause severe CNS Depression and consequently death.

I would take 30 mg at nighttime for Anxiety/insomnia and 15mgs in the mornings or after lunch. It is an excellent antidepressant, however you munch out a lot while on it, and you def put of more weight than before you start the medication. So, if weight gain is an issue for you, stay away from this one. Talk to your physician about alternate choices. Probably the best is Welbutrin if you weight is an issue for you.

I started Mirtazapine last night for severe Anxiety. Slept well, though had very horrible vivid dream that even when i woke it felt like it was still happening. Very hard to get up. Felt very angry, worried myself more about how angry i actually was as i wanted to hurt myself and everyone arond me. All day i've felt monged out could not move to do anything. Can't function so have decided i am not going to continue with them. I was on colpramine for 6 weeks before this and thought the side affects for them were bad but this is something altogether worst-even think i'd rather be severely anxious than feel how i have done so today!!
