I had the mirena IUD for one year and recently had it taken out. In the last 6 months I have had 5 bad spells of vertigo & nausea. Each spell lasted about 3-4 days. I couldn't sleep right and lying down made it worse. I would wake up with the dizziness and gravol didn't help much. I'm not sure yet if it was the mirena IUD, I'm hoping it is and that my life can get back to normal. No doctor has entertained the idea that it is the mirena that caused my symptoms. Some doctors have suggested that I may have meneire's syndrome. I find it odd that I am a healthy individual that has had no real illness until I started with the mirena. I will post again if I stay symptom free since the removal a few weeks ago.
