I take 20mg of lexapro a day for my depression and have been off and on MANY anti-depressants. I find that when I start back on the lexapro it kicks in after 2 weeks. Much sooner than the others. I had to ween off of klonopin a year or so ago and it took forever!!! Every time I thought I had lowered the dose enough to stop the side effects would kick in and make my body feel like someone had beat me up. I was on 2mg of klonopin a day and I think it took me about 2 months to ween off of it (my pdoc said that was normal.) I was weening off of the klonopin to go back on xanax and found that even taking the lexapro and xanax, I still had to taper off very, very slowly. In my opinion klonopin is the worst medication to come off of.
Different people react in different ways to anti-anxiety type meds. You may want to ask your doctor about Cymbalta. If staying on klonopin, maybe switch to a generic as well. Usually it's about two weeks to notice any differences. Good luck!
Yes it's true that some therapeutic lag are longer, especially in your case since you tried to reduce the Klonopin. I would give it more time to see. The switching can indeed be a problem too since Paxil and Lexapro are not the exact same drug even tho both are SSRIs. You might suffer from a little Paxil withdrawal while on Lexapro, this could explain the longer therapeutic lag. The Paxil therapeutic effect slowly stopped after 2 weeks and the Lexapro now hopefully replace it. Give it some more time.
