I had the Mirena for about a half a year. My side effects included cramps, blurred vision, brain fog, nausea, high blood pressure, headaches, extreme fatigue, severe depression, lack of interest in anything, bloating, and extremely dry skin and hair. Also, I had to have two surgeries for atypical cells after my first ever bad mammo. ever. Whether this was related remains to be seen, but the other severe changes to my health make me suspicious. A few weeks after getting Mirena, I thought things would get better, as some of the severe cramping subsided. I was wrong. I had no idea how depressed I was until I had it removed. Honestly, the change after two days post removal was amazing. I could function again. My skin started getting better within a few days. I would have had it out earlier, but like many, my doctor felt I should continue with it. Thankfully, after my second request, he agreed it was a good idea to have it removed. I feel that this is a very dangerous product that certainly affects much of the body. I am aware that many women have no problem with it, but I urge those women who have had problems to report them to the FDA and also consider searching for the Mirena petition site. Otherwise, problems will go under reported, and personally, I do not believe enough studies were done on this product. The manufacturer tells us that side effects are uncommon. What is uncommon? If you have symptoms similar to many others, you should trust yourself. It affected my job and family. I am so happy to have it out.
