I had a change of my vision while on Hydrea. I went to my eye dr and my cornea was swollen. He asked me had there been a change in my meds. I told him about the Hydrea. He immediately asked did I have really dry skin or sores in my mouth. My answer was yes. I immediately contacted by hematologist and he discontinued it and put me on Angralide. I could not take that either. I am now on Besrimi injections every two weeks. Doing good so far.
