Greetings.

Lexapro was a wonder drug for me. Didn't stay on 10mg for long, so I can't tell you how well that dosage worked. I was on 20mg for like, 4 years. Recently bumped to 30mg due to treatment resistant OCD.

Are you taking it for GAD, OCD, or both? I can tell you that especially for OCD, it's the higher doses that will do the trick. That's true of all SSRI's from my understanding. Take that with a grain of salt though, I'm no doc.

Don't give up on Lexapro until you've tried 20mg.
