newbie with questions

hi everyone. i stumbled upon this site a few weeks ago and im so happy that i found it. ive been mainly hanging around the panic/anxiety forums, but since my panic disorder is coupled with depression i though i would post a question here if i may. i started 10 mg of lexapro about 5 weeks ago, and it has helped me alot with my severe panic attacks, but as for the depression, well, its still there. i had a doctors appointment yesterday, and after telling the doc about what i was feeling, she bumped my dosage from 10 mg to 20 mg in hopes of getting me out of this depression. has anyone else had a jump in meds like this, specifically with lexapro, and has it helped? i am terribly afraid of side effects and i am afraid that this much of a jump might bring on some unwelcome ones, so of course ive still been taking only 10 mgs a day until i can get some of your insight on this. the first week or so starting the meds was a bit weird- fatigue, some vertigo, and also some really intense panic attacks, but after a few days i started to feel better. im just wondering if all of those side effects have a chance of coming back?
thanks for taking the time to read this, and thanks in advance for any replies.

ive been on as much as 40 of lexapro a day. I started at 5, went to 10 etc. Of course everyones different, but I didnt get any more sideeffects when i increased the dosage, just got a stronger psychotropic effect from the med. I didnt really have any side effects to begin with on it though other than a bit of fatigue i guess.

I took it for social anx disorder and depression as well. It worked great for anxiety but didnt do much for my depression. Allthough I just started on it a week ago, you might try cymbalta, as it feels very similiar to lexapro. It actually helps with the anxiety a little less than lex but it helps alot more with depression. Id like to be on lex and cymbalta but apparently thats dangerous.
