Antibiotics: Usually two antibiotics are prescribed. The main reasons for failure of H. pylori infection include antibiotic resistance, poor adherence and rapid metabolism of What it's saying is that globally, the H pylori cure rate using the clarithromycin combined with either amoxicillin or metronidazole does NOT work for 3 in 10 people.
