I accidentally took a 5 mg Lexapro with another small white regular CVS brand Tylenol. I am not prescribed this medication nor do I need it at this time in my life - although I do suffer from some anxiety, there's no depression as of yet. After I took this pill about 9 hours ago I have been anxious and uncomfortable. I have not been able to sleep and my mood has been all over the place. When will this medication be out of my system? It was stupid to not look at the pills before I downed them, but I think they were put into the bottle by someone else who got them mixed up in our medicine basket. How long until I can feel my normal self again?
