  • Talk to your healthcare provider before taking XIFAXAN if you have severe hepatic (liver) impairment, as this may cause increased effects of the medicine.
  • Tell your healthcare provider if you are taking drugs called P-glycoprotein and/or OATPs inhibitors (such as cyclosporine) because using these drugs with XIFAXAN may lead to an increase in the amount of XIFAXAN absorbed by your body.
  • In clinical studies, the most common side effects for XIFAXAN were:

    HE: Peripheral edema (swelling, usually in the ankles or lower limbs), constipation, nausea (feeling sick to your stomach), fatigue (feeling tired), insomnia (trouble sleeping), ascites (a buildup of fluid in the abdomen), dizziness, urinary tract infection, anemia (low red blood cell levels), and itching

    IBS-D: Nausea (feeling sick to your stomach) and an increase in liver enzymes

  • XIFAXAN may affect warfarin activity when taken together. Tell your healthcare provider if you are taking warfarin because the dose of warfarin may need to be adjusted to maintain proper blood-thinning effect.
  • If you are pregnant, planning to become pregnant, or nursing, talk to your healthcare provider before taking XIFAXAN because XIFAXAN may cause harm to an unborn baby or nursing infant.
