Painful Bladder Syndrome/Interstitial Cystitis Successful Treatment with Montelukast: A Case Report and Literature Review.

Painful bladder syndrome/interstitial cystitis (PBS/IC) is a chronic condition characterized by pelvic pain, urinary frequency, and urgency for more than six months in the absence of urinary tract infections. The etiology of PBS/IC is still an enigma. PBS/IC is challenging for doctors to diagnose because its symptoms overlap with other diseases such as urinary tract infection, overactive bladder, or endometriosis. Hence, it is diagnosed after excluding those diseases. The prognosis of PBS/IC may vary because of multiple treatment options. In this study, we are documenting a 26-year-old female patient who was successfully treated with montelukast after diagnosed with PBS/IC.
