I have been on Lexapro 10mg for only 3 weeks and started getting terrible side affects. I went from?

Soccer; I hope you are talking with your doctor about this. It is normal to feel bad after the dose increase for a while but anyway. We all react differently to these type of medications normally the doctor give you a tapering dose to go off of these but if you back to 5mg you normally need to stay there for a few weeks if that is about the time you have been taking it then take it either 1 every other day if you do not have any side effects from the withdrawal otherwise you would try 1/2 tablet daily for a few more weeks then 1/2 of that until you are not feeling any withdrawal or at least where you can tolerate it. But really the best idea is to call your doctor Monday and get them to give you a tapering dose. Just better to be safe than sorry. good luck
