During the treatment of Helicobacter pylori, it is not advisable to stop the medication arbitrarily, as doing so may lead to insufficient treatment duration and result in a failure to eradicate the bacteria. Therefore, it is recommended to use a bismuth-containing quadruple therapy for two weeks to eradicate Helicobacter pylori. The specific medications included in this two-week quadruple therapy are a proton pump inhibitor such as pantoprazole or lansoprazole, plus two antibiotics such as amoxicillin, clarithromycin, or metronidazole, combined with bismuth potassium citrate. The medication should be taken under medical supervision. Helicobacter pylori infection can be detected through a carbon-13 breath test or a carbon-14 breath test.
