Helicobacter pylori (H. pylori) is an important cause of peptic ulcer disease and gastric malignancies. The treatment of H. pylori remains a challenge, because many factors determine the success of therapy such as resistance to primary or secondary antibiotics, drug concentrations on the mucosa, patient compliance, side effects and costs.

At the beginning of August, I went to the doctor and had an endoscopy with a stomach ulcer with HP infection. The hospital gave me the medicine for 15 days, but I only took it for 10 or 11 days, then it was lost (because of the epidemic and blockade while I was collecting things at my mother's house, I lost it). Please tell me if I have a stomach ulcer with HP infection, what should I do?
