Ibuprofen (Advil, Motrin, others), naproxen Tricyclic antidepressants,
Antihistamines,which may reduce urinary urgency and frequency and relieve other symptoms.Pentosan (Elmiron), is the only oral drug approved by the Food and Drug Administration specifically for interstitial cystitis
2-Trans-cutaneous electrical nerve stimulation (TENS) uses mild electrical pulses to relieve pelvic pain and, in some cases, reduce urinary frequency. Electrical wires are placed on your lower back or just above your pubic area,another possible nerve stimulation treatment is sacral nerve stimulation.
3-Some people notice a temporary improvement in symptoms after undergoing cystoscopy with bladder distention. Bladder distention is the stretching of the bladder with water or gas.

Doctors rarely use surgery as interstitial cystitis treatment because removal of part or all of the bladder doesn't relieve pain and can lead to other complications.
