Hi. Thanks for your query. Noted the history and understood the concerns. Since you are a known patient of H pylori infection but the medicines caused reaction, you can discuss with your Doctor to get started on the following medicines under supervision. Amoxicillin and/or Clarithromycin work the best so wither of these be tried along with Pantoprazole or Ranitidine; all these things done after consent and guidance of your Doctor. In addition you can have the following: Antacids every three hours. Domperidone is there is GERD or reflux. Soft bland diet. Plenty of oral fluids. Avoidance and/or treatment of stress as this is one of the most important instigating or enhancing factors. This way you can get a good control and ever cure with the presenting problems.
