Hmm... 2.5mg of Lexapro is indeed a small dose. Unless things have changed recently, I believe the smallest dose is 5mg because I used to take 5mg. So I'm guessing you're splitting the pill in half?

I didn't find 5mg helpful. The "accepted" minimum therapeutic dose is 10mg. Of course, some people are sensitive to meds and may need less than the "accepted" minimum therapeutic dose to achieve a therapeutic effect, but I just thought I'd mention that.

In the end, I went off lexapro because 5mg wasn't helpful. I was on 10mg at one point, but it made me manic. The only reason I stayed on 5mg for so long is that the withdrawals from the med were too much to bear. Fortunately, I was able to switch to Zoloft with no problem with the help of my pdoc. Seems that it's easier to taper off an SSRI if you have another SSRI in your system.

But yeah, just thought I'd mention therapeutic doses vs mania. Be careful with Lexapro if your pdoc does increase the dose. It took me 1-2 weeks before I became manic, but it was pretty fast.
