I have been diagnosed with Interstitial Cystitis. This is a very debilitating condition. Pain becomes the new norm. Luckily for me, I have a great urologist. He prescribed this medication for me about eight years ago. I was told at the time that once I was on it, I would be for the rest of my life. This is the only medication on the market for this condition. It is extremely expensive even with insurance and there are no generics available. There is also no choice. The pain takes that choice away. I am so very appreciative that this medicine has been effective for my condition. There is no cure for this condition but it can be effectively managed if you have a caring urologist. My symptoms have subsided over the past few months and I have been able to stop taking this medicine. Although I can't venture to say why I am better, I am grateful. Still, it is a comfort to know that this medicine is available if my symptoms return. This medicine is highly recommended by me.
