Had endoscopy done all clear nothing at all but still get acid takeing lanzoprozole but dont work any reconmendation?

Usually. Prevacid (lansoprazole) helps with acid reflux. If use of proton pump inhibitors, GERD precautions like Upright 1 hour b/f and after meals, no smoking, minimizing alcohol, avoiding NSAIDS, small frequent meals and HOB elevation do not improve symptoms, alternative diagnosis may be considered.
