Hey Laura
Lexapro can help with both depression and anxiety by elevating levels of the chemical, serotonin, in your body.
I am going to give you the link to some very detailed information about Lexapro found right here on Health Central.
I am also going to give you this link to the official Lexapro site with FAQ's to read.
Hope this helps some. Perhaps someone who is currently taking Lexapro can chime in and talk about their experience using this drug for anxiety.
Thank you for your question.
