I started taking Lexapro at the end of May 2017. I started out on 10mg and it worked great, as I was depressed and have never been on anti depressants before. However, in June my dose bumped up to 20mg and it has been fine but here lately, I have noticed that I have been super irritable and I get irritated at the littlest things. I have no idea why this is happening but I want it to stop.
