Are you saying that it is doubtfull that Lexapro will even work. I hope not because I do want to give it a fair trail. I have been on it for 3 and 1/2 weeks
and have had a few really good days and the rest seem normal (normal for me). I am thinking if it's the same at a month to go to 15 mg. Is a month a fair trail or should one wait for 6 weeks????> I have noticed headaches as well. It started about the same time as the irritability. I am thinking about switching back if this doesn't get better soon!

PDoc recently asked me to consider switching to Lexapro, which is similar to Celexa without the isomer that causes most of the side effects. However, the Lexapro made me extremely anxious so possibly the sleepiness side effect of Celexa was what I needed. I went back on the Celexa feel better but back to the usual sedation problem....

Any biologist could tell them that when mirror-image isomers of molecules exist, it tends to be so that most of the biological activity resides in one isomer and the other is nearly inactive. However, the isolated-isomer version of Prozac never made it to market because it turned out to be dangerous, so the "one isomer active" rule may apply more to naturally occurring substances than it does to synthetic drugs.

(There could be a few individual exceptions.) Same goes for Nexium compared to Prilosec and all these other analogous "next-generation" pills.
