Hi Boolah, welcome to Healing Well forum! I just wanted to say that it would take a couple of weeks for the Lexapro to start working or any antidepressant for that matter as they have to work up to what is called a theraputic level in the body. They dont just start to work at full level the first day or two that you take them.
Nikki - Boolah makes a good point with the Tylenol also, I couldnt find any drug contradications regarding this but it is possiable. Your pharamist is always a good place to start if you have any questions regarding your medications. They can pull up what you take and you can tell them of any OTC's that you may have questions about. ~elisha
