Hi all,
I changed over to Fluoxetine from venlafaxine 8 weeks ago now. I did 3 weeks on 20mg, 2 weeks on 30mg and then 3 weeks ago I increased to 40mg and reduced my mirtazapine from 45 to 30mg.
I’m feeling pretty rubbish, OCD has increased and my mood is very low. I’ve read that this is a slow drug so do I just give it more time? I’ve done 8 weeks in total but do I need to wait 8 weeks at my current dose before I see a difference?
I was told to give Prozac 6 months to get full effect.
The long fluoxetine half-life has several positives, but the downside is you can age appreciably waiting for it to kick-in. It takes about a month just for fluoxetine plasma levels to stabilise after a dose increase (or decrease). I can't say how long you may still need to wait as that comes down to individual biology, but my guess is another 3-4 weeks is likely and as Nicola has said, the full effect can take much longer. Sorry :sad:Quote:

Thanks guys, so looks like I need to try and be a little bit more patient with myself. 4 weeks on 40mg now and still feeling incredibly anxious with lots of intrusive thoughts. I feel completely disconnected from my family and I feel completely intolerant of my in laws. Looked at the side effects list and feeling hostile is listed there so I guess that’s why.
I noticed that I posted this on the venlafaxine thread but meant to put it on the fluoxetine one. Is there anyway it can be moved?
Still got loads of anxiety/OCD, nearly 6 weeks on 40mg now and I am just wondering if it is possible I could still be feeling some withdrawal effects from coming of the ven and lowering the mirtazapine? I stopped ven completely 11 weeks ago.
It is too early to draw any conclusions for this as fluoxetine can take quite a while to kick-in due to its very long half-life. It may take up to 12 weeks to get a positive response and even longer to get the full effects. :sad:Quote:

Mirtazapine's most common withdrawal symptom is insomnia, however, it could be contributing to to the anxiety/OCD.Quote:
