The statement that H. pylori is most afraid of three kinds of tea is wrong. To treat H. pylori infection scientifically, you can usually use quadruple therapy, which is two antibiotics plus a PPI (proton pump inhibitor) plus a bismuth agent. Antibiotics that can kill H. pylori in the body include clarithromycin, metronidazole, amoxicillin, tetracycline, and levofloxacin. Proton pump inhibitors and bismuth are effective in inhibiting H. pylori infection and together with antibiotics can synergize to kill the bacteria. No single drug can successfully treat H. pylori, and a combination of drugs is necessary. Quadruple therapy such as amoxicillin, clarithromycin, colloidal bismuth pectin, and omeprazole are commonly used. Routine post-treatment review is required, which should take place 4 weeks after the end of regular treatment. Proton pump inhibitors should be discontinued for 2 weeks and bismuth and antibiotics for 4 weeks before the examination. After failure of eradication therapy, two other antibiotics can be switched, and the choice of antibiotics should be based on local resistance. H. pylori eradication treatment needs to be carried out under the supervision of a doctor, and should not be taken by oneself.
