Has anyone upped their dosage of Fluoxetine and felt a great difference?

Posted , 6 users are following.


I am currently on 20mg of Fluoxetine for anxiety. I am in my 8th week now and during week 5 & 6 I felt much better however last week and this week I am waking up with the anxious stomach etc. I feel very flat too which is very unlike me. I am wondering if it just needs more time to begin making a bigger difference or if I need to up my dosage. Does anyone have any words of advice? I also wondered if these symptoms are due to being pre menstrual. Does anyone find that they feel differently the week before their period begins?

Thanks for taking the time to read this.

    Hi sally.

    I increased my dose to 40mg after week 4 with the advise from my gp.

    I noticed feeling better a couple days in the higher dose,  coincidence? ? 

    I spoke to a friend whose a pshychologist recently who told me that 20mg is a low dose so that made me feel better as I was thinking 40mg was too high.

    Im now on my 7th week fluoxetine,  3rd week at 40mg and my head is feeling better but still not 100% .

    I am trying to be patient and going to see how I feel aftet 10 weeks.

    I think the important thing is to go to your gp to discuss. 

    Hope this helps

    Dear Sally,

     Fluoxetine is a subjective thing. Initially I was started on 40mg/day and I just couldn't handle the side effects. I consulted my doctor and we agreed to reduce to 20mg which worked fine for me (with the background anxiety at times). Now I am at 10mg, and hopefully will taper it off in a few months time.
