After Using Aquafor And Increasing My Antidepressant Doxepin I Am

After using aquafor and increasing my antidepressant doxepin I am hypersensitive one of the worst, I received a rash afterwards like a reaction I had a very bad one from using gerd medicine prevacid and taken off then omeprazole take off. I was always plagued with psoriasis but this isn't that it looks different and itches a lot, my psoriasis only itches occasionally this is burning and itchy after using aquafor Is this a reaction?
