What side effects does Xifaxan (rifaximin) cause?
Xifaxan (rifaximin) can cause side effects, but many people tolerate it well. The most commonly reported effects include gastrointestinal symptoms such as nausea, abdominal pain, and bloating. Some patients also report headache and fatigue.
What are the more serious Xifaxan side effects to watch for?
Serious reactions are less common, but you should seek medical care promptly if you develop signs of an allergic reaction (such as rash, swelling of the face or throat, or trouble breathing). Contact a clinician quickly if you experience severe or worsening abdominal pain, persistent diarrhea, or symptoms that feel out of proportion to typical side effects.
Does Xifaxan for IBS-D have different side effects than Xifaxan for hepatic encephalopathy?
Yes. Xifaxan is used for different conditions, and the side-effect profile can vary by indication. In particular:
- For IBS-D (irritable bowel syndrome with diarrhea), gastrointestinal complaints are common since the drug is taken for a bowel-focused problem.
- For hepatic encephalopathy (liver-related brain dysfunction), side effects can overlap with symptoms patients may already have from liver disease, so clinicians monitor closely for changes after starting treatment.
What side effects are patients most likely to ask about?
People commonly ask about:
- Ongoing diarrhea or stomach upset while on treatment
- Headache or fatigue
- Whether side effects mean the drug is not working
- When to stop and call a doctor
In most cases, mild effects can be monitored, but worsening symptoms or allergic-type symptoms should be reported right away.
When should you contact a doctor urgently?
Get urgent medical help if you have signs of an allergic reaction (hives, facial swelling, trouble breathing) or if symptoms become severe—especially severe abdominal pain, persistent/worsening diarrhea, or other rapidly escalating effects.
Are there long-term risks from Xifaxan?
Because rifaximin acts largely in the gut (it is poorly absorbed compared with many other antibiotics), long-term systemic side effects are generally less of a concern than with some other antibiotics. Still, any prolonged or unusual symptoms should be discussed with a clinician.
