Hey Tami


It sounds like you are worried that your dosage is too much?  Are you experiencing any bad side effects from the increase in dosage?  Are you feeling better, worse, or the same?  Your doctor must feel confident that this is a good level for you.  I am not a doctor but I would imagine it would take several weeks to feel the full effects of this change. 


I have some information here about Prozac from Health Central.


Your best bet is going to be to call your doctor with your concerns and ask what to expect at this higher dosage. 


I wish you the best.

I increased my meds from 10mg to 20mg to 30mg and then to 40mg 4 wks. ago and I really didn't think it was working because I didn't feel any better by increasing to 40.  But by the end of the 4th wk. I did notice some slight improvements.  Each dosage gave me some improvements but not what I needed.  It takes time to find the right dosage.  So it does take time.  Do you not notice any difference or are you having side effects from increasing it?  Either case talk to your dr.  I see mine next wk.and I let him know eveything.  He usually tells me to give any changes to my meds. 4 wks. before we consider increasing, but that is how my dr. works.  So I may even increase again if we both feel it would give me more relief.  This is just my personal experience with meds.
