Interstitial cystitis/painful bladder syndrome<unk>  may be used either by mouth or in the bladder to treat interstitial cystitis/painful bladder syndrome (IC/PBS). An older review found improvements in pain (36%), urgency (28%), and frequency (54%), but that it does not change the frequency of urination at night. More recent trials, however, found it to be of no benefit. Osteoarthritis<unk>  has been studied in knee osteoarthritis, though evidence to support such use is poor as of 2003. There is some theoretical evidence that it should help.
