I have been diagnosed with interstitial cystitis five years ago. I started taking Elmiron at that time. I became weak and had trouble catching my breath. I thought it was my autoimmune Sjogrens Syndrome. I believe now that it is the Elmiron. I was in heart failure a year later: my heart couldn’t keep up with the accumulation of fluid due to a stiffening of the heart muscle (diastolic dysfunction). I have gotten progressively worse. I stopped taking Elmiron two days ago and I have slept the best in five years. Still having difficulty breathing but it doesn’t feel life threatening yet. Any recommendations for me? Thank you, Linda Edminsten
