I got Mirena in April 2009. After 2 weeks I started noticing I was getting hives. At first it was not that bad but the hives got worse and worse. I reacted allergic to my supplements and started to react to food. Even though I was on a strict diet to avoid anything that could possibly cause any reaction the hives were getting worse. I had Mirena taken out yesterday. My doctor thinks I had an allergic reaction to Mirena. I still have the hives. I have lost lost of weight and life is pretty hard when you have hives non stop! I hope it get better.......
