For patients with positive H. pylori, the most important thing is to sterilize the treatment, which can be done with a triple or quadruple drug. In general to include two antibiotics, and proton pump inhibitors and pectin secretion, you can choose clindamycin capsules + metronidazole + Lizudra + omeprazole enteric capsules. This combination can be taken orally for about two weeks, then stopped for a week and given again to recheck the breath test to see if the H. pylori is still positive. If the value of H. pylori is still high, it is recommended to take the triple drug or quadruple drug again for one cycle. In addition, during the treatment period, we should pay attention to the meal sharing system to avoid infecting others. When eating, avoid smoking and alcohol, and do not eat spicy and stimulating food.
