Primary Outcome Measures :
  1. Change in stool consistency [ Time Frame: At Week 4 and Week 12 ]
    Stool consistency as measured by the Bristol Stool Form Scale. Change from baseline at Weeks 4 and 12 will be determined.

  2. IBS pain severity [ Time Frame: At Weeks 4 and 12 ]
    Pain intensity as measured by the 11-point numeric rating scale (NRS) will be averaged for each 4-week interval. Change from baseline at Weeks 4 and 12 will be determined.

Secondary Outcome Measures :
  1. Change from baseline in quality of life scores (IBSQOL). [ Time Frame: Week 12 ]
    Change from baseline in IBSQOL scores will be calculated at Week 12.

  2. Change from baseline stool frequency. [ Time Frame: Week 4 and Week 12 ]
    Stool frequency will be measured as the mean number of times per day that stools were passed, and will be averaged for each 4-week interval. Change from baseline at Weeks 4 and 12 will be determined

  3. Change from baseline in fecal urgency. [ Time Frame: Week 4 and Week 12 ]
    Proportion of days with fecal urgency will be calculated for each 4-week interval and change from baseline will be determined at 4 and 12 weeks.

  4. Change from baseline in lost productivity. [ Time Frame: 12 Weeks ]
    Lost workplace productivity and number of days IBS symptoms interfered with social/leisure and household activities will be determined at baseline and week 12. Change from baseline to week 12 will be calculated.
