Basically I am currently taking Prozac. My doctor recently changed my doze to a higher one. However, a few days ago I started getting this bad rash (hives). I have tried everything and we know for sure it is not any type of food or detergent that I am using. I also have tried different types of soaps and shampoos but I cannot get rid of it. Is it possible for the Prozac to be causing this? I was also prescribed Doxycycline but it has not helped. Could this also be caused be stress/ anxiety?
