    How should I get ready for this test?

    • Do not eat for 4 hours before you have the test. You may have sips of water.
    • You must check with your doctor if you should stop your Prilosec, Prevacid, Aciphex, Protonix, Nexium, Zegarid or Kapidex. If you are told to stop the medicine, you must stop 5 days before your test.
    • You may take these medications up to midnight the day before your test: Antacids (Maalox, Tums, Rolaids), Tagamet, Zantac, Pepcid, Axid

    • We may numb your nose and throat to pass a small tube through your nose and into your esophagus. This allows us to measure how much acid comes up into your esophagus.
