Causes
Interstitial cystitis (IC) is a painful condition caused by inflammation of the tissues of the bladder wall. The cause is unknown. The condition is usually diagnosed by ruling out other conditions (such as sexually transmitted disease, bladder cancer, and bladder infections).
IC is frequently misdiagnosed as a urinary tract infection, and patients often go years without a correct diagnosis. On average, there is about a 4-year delay between the time the first symptoms occur and the diagnosis is made.
More than 700,000 Americans have IC. The condition generally occurs around age 30 to 40, although it has been reported in younger people. Women are 10 times more likely to have IC than men.
Treatment
There is no cure for IC, nor are there any standard or consistently effective treatments. Results vary from individual to individual. As long as the cause is unknown, treatment is based on trial and error until relief is found.
Elmiron is the only medication taken by mouth that is specifically approved for the treatment of IC. This medicine coats the bladder like Pepto-Bismol coats the stomach.
Other medicines may include:
- Tricyclic antidepressants such as Elavil (amitriptyline) may relieve pain and urinary frequency
- Vistaril (hydroxyzine pamoate), an antihistamine that causes sedation helps reduce urinary frequency
- Opioid painkillers for severe pain

- Emotional trauma
- High costs associated with frequent medical visits
- Chronic depression
- Side effects of treatments (depending on the treatment)

Outlook (Prognosis)
Treatment results vary. Some people respond well to simple treatments and dietary changes. Others may require extensive treatments or surgery.
Exams and Tests
Diagnosis is made by ruling out other causes. Urine analysis, urine culture, and urine cytology tests are essential.
Usually, cystoscopy (endoscopy of bladder) and bladder biopsy are performed. The characteristic finding of interstitial cystitis during cystoscopy is pinpoint bleeding in the lining of the bladder or ulcers on the bladder wall.
In IC, the bladder does not hold as much urine as a normal bladder typically does.
A procedure called video urodynamics can reveal how much urine needs to be in the bladder before the patient feels the need to urinate.
