Nowadays, for the treatment of H. pylori, the traditional quadruple therapy is usually chosen. Quadruple therapy is a combination of a proton pump inhibitor, a bismuth agent plus two antibiotics for the treatment of H. pylori. 1, proton pump inhibitors: omeprazole, rabeprazole, esomeprazole, pantoprazole, etc., are generally two capsules twice daily. 2, bismuth: bismuth potassium citrate, colloidal bismuth tartrate or colloidal bismuth pectin. It is usually applied four times a day or equivalent dose twice a day, taken before meals. 3, two antibiotics: amoxicillin capsule 1.0g, 2 times/day, taken orally after meals, metronidazole 0.4g, 2 times/day, taken orally after meals, if amoxicillin is allergic or resistant, clarithromycin, levofloxacin, etc. If the above treatment fails, the antibiotics can be changed to amoxicillin plus tetracycline. The course of conventional treatment is usually seven to fourteen days. For some recurrent H. pylori or refractory H. pylori, the recommended medication for treatment is two weeks. H. pylori is retested after one month. You need to share meals with others and not drink alcohol while taking the medication. Pay attention to a proper diet. As long as you take your medication on time and pay attention to your diet, H. pylori can be cured, don’t worry. The medication for H. pylori treatment is complex, so it is recommended to see a doctor at the hospital before using the medication.
