My son is 12 yrs old initially he was diagnosed h pylori through endoscopy in August he was given clarithromycin 500 mg 1.0.1,  Metrogyl 400 mg 1.1.1 and Pantocid 40 mg 1.0.1. for 14 days. He had bit improvment after the course but had consistent burps and stomach pain he continued with Esograss fast 40 mg 1.0.1 and Ganantonin 50 0.1.0 he had improvement but still had stomach pain and vomit like with continuous burps and pain after eating. We had again endoscopy in November he again got diagnosed with H Pylori and was given Metmox 500 1.1.1, Bisgram 120 1.1.1 and Vonefi for 14 days but as medicine were heavy he was able to take for 7 days only. As of now he is still having stomach pain and continuous burps, His liver reports, thyroid and blood reports are normal. Why are conditions not improving please guide. Mayank Sharma 75xxxxxx60.
