H. pylori usually requires about two weeks of medication, as uncontrolled H. pylori infection tends to aggravate the symptoms of gastritis. Treatment of H. pylori infection is usually treated with ppi or h2 receptor antagonist, combined with two antibiotics, for example, amoxicillin, metronidazole, clarithromycin, furazolidone and other drugs. After taking a course of medication and then stopping, one month should pay attention to review the C13 and C14 test to clarify whether H. pylori is completely cleared. If not completely cleared, you need to continue to take the drug treatment. HP has a great invasive power on the gastric mucosa, but also lead to hyperprolactinemia, so HP infection should be timely treatment.
