interstitial cystitis
"I have been taking Elmiron for about 7 years for interstitial cystitis. It had no effect on me for the first 6 months but then suddenly began to work very well. I had trouble remembering to take it 1 hour before or 2 hours after eating and would skip it if I forgot. I gradually realized that one 100mg dose a day was just as effect as taking three, so I changed to that as my goal dosage. I have experienced some hair thinning at the crown of my head, but since I am 70 years old I cannot be sure that was caused by Elmiron. When there was a mysterious halt in manufacture of the drug several years ago that lasted for several months before resumption, the symptoms of interstitial cystitis reappeared after a couple of weeks."
