A couple days: Aciphex/rabeprazole is a proton pump inhibitor: these drugs bind to an enzyme (proton pump) located on stomach parietal cells and block the production of hydrogen ions. So then the hydrogen ions can't combine with chloride ions to form gastric/stomach acid. This blockage/inhibition lasts about 48 hours after which new proton pumps are synthesized and resting proton pumps are reactivated. Stay well

24-48 hours: The medication has a half life of 1-2 hours, so it is no longer in your system somewhere between 3 and 12 hours after your last dose, depending on your individual metabolism of the medication.

Depends: What dose and how long did you take the Aciphex (rabeprazole)? Most people start making acid within 48 hrs. It may be slightly more than usual initially but should revert to normal within a week. Generally there are no other effects on your system.
