What happens if antibiotics don’t work for H. pylori?
EVIDENCE-BASED ANSWER: Treating patients with Helicobacter pylori infection who have failed clarithromycin-based triple therapy with either levofloxacin-based triple therapy (with amoxicillin and a proton pump inhibitor [PPI]) or a bismuth-based quadruple therapy produces cure rates of 75% to 81%.
How do you know when H. pylori is gone?
