Hi.
I did some looking for you on the net and found that one of the side effects of Lexapro is nervousness. Could that be what's causing you to be really talkative and hyper???
Do you suffer from mania? Bipolar? Because the drug indications say that someone who suffers from it should be closely monitored on this medication because it can make the condition worse....and may need adjustment. Just a thought.
If you want to look up the information on your meds, there is a link on this site and also, my favorite:
http://www.medlineplus.org
There are several with reliable information and actually Lexapro has an official site.
http://www.lexapro.com
Hope this helps a little bit. You might can find more information that makes more sense on those sites.
Take Care,
Kimberly
