Phenazopyridine
interstitial cystitis
"When my IC flares up (like it did last night when I drank a huge glass of orange juice--big mistake) and I can't sleep because of that horrible ache, one dose of this stuff works for me. I get the maximum strength OTC generic from CVS (Walgreen's has one, too) but even if you have to pay full price for the brand name, it is worth it. I'm so glad I found this drug.  I do have a box of thin maxi-pads left over from when I had periods, and since I'm at that age where I leak a bit, I wear these to keep my underwear and bed sheets from turning psychedelic orange."
