How long would it take to get off 15mg Lexapro (escitalopram) which I am taking for 5 years for G A D.I am on 50 amityripiline also and I find it better. Thanks?

Work w/ Dr. Tapering is the right plan and your best option is to work w/ the Dr on a schedule suited to you. I'd expect it to be safe to be off w/in a few months - but let the Dr plan it w/ you. Best!
