I was put on Effexor in june of this year for my PTSD , particularly to help with anxiety and panic attack symptoms. I was originally started on the lowest dose and my DR is slowly working up to 150mg , I am however very med sensitive , I am also on Mirtzapam and then have Benzodizapam PRN.
I have found that Effexor has been really effective , prior to taking it I could barely leave the house, would break down crying all the time, I would hide in my bathroom out of fear as that was the only place that felt safe,I couldn't think straight, there were days where I physically was unable to move because the anxiety was so bad and I was having around 4-5 panic attacks daily. All of this has stopped since I have been on Effexor ( we did try other medications prior) I still am very anxious but I am functional and can engage my skills enough to deal with the present level of anxiety.
I take it at night as it makes me very sleepy.
In terms of side effects when I first started on it , It made me feel nauseous , it made me incredibly sleepy , low energy and I retained urine and it made me rather constipated (Sorry tmi ) and brain zaps.
The nausea lasted for about 2 weeks each time we increased , the sleepiness wore off within a month , the low energy is still present however this could also relate to just being a PTSD consequence (or the fact that I work , volunteer and am studying postgrad) , the urine retention lasted about 2 weeks , the constipation lasted about 6 weeks , the brain zaps are still present.
In order to handle the brain zaps , sleepiness and nausea I take it at night 30mins before I want to go to sleep and it puts me asleep within 30mins of taking it , I know that pretty much when the brain zaps start i need to close my eyes and i'll be asleep within minutes.
One side effect which I just learnt about today and I wish my doctor had warned me about , is that it turns out it can impact your vision and as a result I've found out today I needed glasses and when I said i was on this medication they informed me this was a side effect for some people ( So having just turned 24 and having no prior eye issues to be needing to wear glasses every time i concentrate thats a really crappy side effect )
