***Does anyone know why the standard dose of aciphex is 20mg, while the standard dose of protonix and nexium is 40mg? Does this mean the aciphex is weaker or stronger? My pharmacy said they are just diff meds and can't be compared. I don't believe that. I had to stop nexium due to insurance-and I just started aciphex today. I'm scared my symptoms will return. Should I ask my Dr if I can take 2 aciphex? Does anyone here know why the dosing is different? Thanks!
