The resistance problem

Due to increasing antibiotic resistance and long-term health consequences, H. pylori is categorized as a public health threat by the FDA.1

The American College of Gastroenterology guideline for H. pylori states that...

“Resistance to clarithromycin, metronidazole, and, increasingly, levofloxacin limits the success of common eradication regimens in use today.”2

...as a result, the guideline recommends against using clarithromycin-containing regimens...2

Consequences of not eradicating H. pylori infection

If not eradicated, H. pylori infection can cause chronic progressive gastric inflammation which can lead to3:

  • Atrophic gastritis
  • Gastric and duodenal ulcers
  • Gastric cancer

In fact, approximately 90% of noncardia gastric cancers are H. pylori-related.4
