Can i take protonix (pantoprazole) and ranitidine together?

No advantage: Protonix (pantoprazole) works best if taken before a meal (preferably breakfast) and ranitidine around a meal or at bedtime. No advantage in taking both at the same time.

Yes: No known interactions so they should be safe to take together. However, if your symptoms are bad enough to need double therapy like that, I would make sure your MD knows about to consider further investigation if these symptoms persist or progress.
