IC may often look like other pelvic or bladder conditions.1 Therefore it is critical to thoroughly examine patients who present with symptoms commonly associated with IC.

IC symptoms can mimic the symptoms of unresolved overactive bladder (OAB)

    Consider IC in patients who present with
  • Urinary urgency and frequency (≥8 voids/day)
  • Urgency associated with bladder pain
  • Pelvic pain relieved upon urination
  • Pain during sexual intercourse
  • Symptoms unresponsive to anticholinergic therapy for presumed OAB


    Pain is a characteristic symptom of IC, but not OAB, and may help differentiate between the 2 conditions2
  • In patients with OAB, urgency is associated with fear of leakage, whereas in patients with IC, urgency is associated with bladder pain 3
    Findings suggest a high prevalence of IC in patients with OAB symptoms refractory to anticholinergic therapy 4
  • A study showed that 25 of 47 patients with detrusor overactivity did not respond to therapy with 1 anticholinergic medication4
    • 96% (24 of 25) of those patients were diagnosed with IC*
*Based on a positive Potassium Sensitivity Test (PST).

IC Cast: Interstitial Cystitis or Overactive Bladder?
Watch this informative and entertaining video vignette featuring leading IC KOLs key opinion leaders Dr Robert Evans and Dr Scott MacDiarmid. During the video, they discuss OAB as a mimicking condition and offer tips and advice on how to screen for, diagnose, and treat IC.

IC symptoms can mimic the symptoms of a urinary tract infection (UTI)

    Consider IC in patients who present with
  • Urinary urgency and frequency (≥8 voids/day)
  • Pelvic pain, usually relieved upon urination
  • Pain during sexual intercourse
  • A negative urine culture
  • A history of recurrent UTIs unresponsive to antibiotic therapy


    Millions of women seek treatment for UTI symptoms every year2
  • A study showed that 60% of patients (18 of 30) with IC were initially diagnosed with a UTI3

IC symptoms can mimic the symptoms of endometriosis

    Consider IC in patients who present with
  • Pelvic pain and flares associated with menstruation
  • Pain during sexual intercourse
  • Symptoms unresponsive to endometriosis therapy




    Endometriosis and IC may coexist
  • 86% of patients diagnosed with endometriosis at a pelvic pain referral center were also diagnosed with IC (N=134)2
  • 96% (n=58) of women with chronic pelvic pain were diagnosed with IC, and 80% (n=48) had biopsy-confirmed active endometriosis3

    Consider IC in patients with unresolved endometriosis
  • More than half of women treated for endometriosis continued to experience symptoms, including pelvic pain (N=24)4

IC symptoms can mimic the symptoms of chronic pelvic pain (CPP)

    Consider IC in patients who present with
  • Generalized pelvic pain for ≥ 6 months
  • Pain during sexual intercourse
  • Pain with bladder filling
  • Urinary urgency








    Pelvic pain may be an indicator of IC
  • 79% of patients at a regional pelvic pain center who suffered from persistent pelvic pain (pre- and post-hysterectomy) were diagnosed with bladder dysfunction consistent with IC (n=88)2
  • In a study of 45 women scheduled to undergo laparoscopy for CPP, 38% were diagnosed with IC3

IC symptoms can mimic the symptoms of vulvodynia

    Consider IC in patients who present with
  • Chronic pelvic pain
  • Pain during and after sexual intercourse
  • Vulvar pain








    IC and vulvodynia may have overlapping symptoms due to a common etiology2
  • Patients presenting with vulvodynia may have underlying IC that is causing or contributing to their pain
  • Vulvodynia and IC may occur concomitantly
    • In a study of 46 women with IC or symptoms of vulvodynia (focal vulvitis), 24% had both condtions2

IC symptoms can mimic the symptoms of chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS)

    Consider IC in patients who present with
  • Voiding symptoms (urgency, frequency [≥8 voids/day],nocturia)
  • Generalized pelvic pain
  • Pain during sexual intercourse
  • Pain with bladder filling
  • Unresolved symptoms after empiric antibiotic therapy


    Men presumed to have CP/CPPS who are unresponsive to antibiotic therapy may suffer from IC
  • In 3 separate studies, 58% to 90% of men with CP/CPPS had cystoscopic findings consistent with IC*2-4


*58%, N=60; 60%, N=20; 90%, N=30.
