My mother was diagnosed with ulcer in stomach after we met a doctor as she was suffering from continuous burping for several days. Doctor her prescribed with Sompraz HP for 2 weeks and later prescribed with certain proton pump inhibitors. She felt better a little (20%) after taking sompraz hp for two weeks, however things become worst again when she stopped taking this medicine. Is it okay if start taking Sompraz HP again and also suggest how long it is safe to this Medicine.
