The associated 1-page summary (“Spotlight: IBS Treatment“) on pg 153 reviews society guidelines on testing in IBS. This includes for IBS-D celiac serology, calprotectin/lactoferrin, CRP, possilby Giardia antigen (if in endemic area) and possibly bile acid diarrhea testing. Not recommended include food allergy/sensitivity testing, colonoscopy if <45 years and lactulose or glucose hydrogen breath testing. This 1-page summary details therapeutic dosing and costs. Monthly costs of selected medications according to this report:

  • Lubiprostone (Amitiza): $374
  • Linaclotide (Linzess): $523
  • Pleacnatide (Trulance): $528
  • Tegaserod (Zelnorm): $480
  • Tenapanor (IBSRELA): $1680
  • Rifaximin (Xifaxan) $1544 (for 14 day course)
  • Eluxadoline (Viberzi): $1550
  • Alosetron (Lotronex): $1457-1929 (starting dose), $2915-3859 (max dose)

My take: These guideline publications provide comprehensive information regarding potential pharmacological therapies.
