I have been taking prednisone for over two weeks for a severe photo-allergic reaction caused by another medication. Today was my very last pill and I am thrilled to be off the medication. At first, I was really happy and relieved that the prednisone worked so well on my allergic reaction, but now I am more worried about the side effects of the prednisone. I have experienced severe sleep loss, edema and weight gain. I am hot all the time and sweat like there is no tomorrow. I am worried sick that the medication has further thrashed my immune system too.
