  • Take PREVACID or PREVACID SoluTab at least 30 minutes prior to sucralfate [see Drug Interactions (7)].
  • Antacids may be used concomitantly with PREVACID or PREVACID SoluTab.
  • Missed doses: If a dose is missed, administer as soon as possible. However, if the next scheduled dose is due, do not take the missed dose, and take the next dose on time. Do not take two doses at one time to make up for a missed dose.

PREVACID capsules

  • Swallow whole; do not chew.
  • For patients who have difficulty swallowing capsules, PREVACID capsules can be opened and administered orally or via a nasogastric tube in the soft foods or liquids specified below.
  • Administration of PREVACID in foods or liquids other than those discussed below have not been studied clinically and therefore are not recommended.
    Administration in Soft Foods (applesauce, ENSURE pudding, cottage cheese, yogurt or strained pears):
    1. Open capsule.
    2. Sprinkle intact granules on one tablespoon of either applesauce, ENSURE pudding, cottage cheese, yogurt or strained pears.
    3. Swallow immediately.
    Administration in Liquids (apple juice, orange juice or tomato juice):
    1. Open capsule.
    2. Sprinkle intact granules into a small volume of either apple juice, orange juice or tomato juice (60 mL – approximately two ounces).
    3. Mix briefly.
    4. Swallow immediately.
    5. To ensure complete delivery of the dose, rinse the glass with two or more volumes of juice and swallow the contents immediately.
    Administration with Apple Juice Through a Nasogastric Tube (≥16 French)
    1. Open capsule.
    2. Sprinkle intact granules into 40 mL of apple juice.
    3. Mix briefly.
    4. Using a catheter -tipped syringe, draw up the mixture.
    5. Inject through the nasogastric tube into the stomach.
    6. Flush with additional apple juice to clear the tube.

PREVACID SoluTab

  • Do not break or cut.
  • Place the tablet on the tongue, allow it to disintegrate, with or without water, until the microgranules can be swallowed. Do not chew the microgranules.
  • The tablet typically disintegrates in less than one minute.
  • Alternatively, for children or other patients who have difficulty swallowing tablets, PREVACID SoluTab can be administered with water via oral syringe or NG tube as follows:
    Administration with Water in an Oral Syringe
    1. Place a 15 mg tablet in oral syringe and draw up 4 mL of water, or place a 30 mg tablet in oral syringe and draw up 10 mL of water.
    2. Shake gently to allow for a quick dispersal.
    3. After the tablet has dispersed, administer the contents within 15 minutes of mixing into the mouth. Do not save the water and microgranule mixture for later use.
    4. Refill the syringe with approximately 2 mL (5 mL for the 30 mg tablet) of water, shake gently, and administer any remaining contents.
    Administration with Water via a NG Tube (≥8 French)
    1. Place a 15 mg tablet in a catheter-tip syringe and draw up 4 mL of water, or place a 30 mg tablet in a catheter-tip syringe and draw up 10 mL of water.
    2. Shake gently to allow for a quick dispersal.
    3. After the tablet has dispersed, shake the catheter-tip syringe gently in order to keep the microgranules from settling, and immediately inject the mixture through the NG tube into the stomach within 15 minutes of mixing. Do not save the water and microgranule mixture for later use.
    4. Refill the catheter-tip syringe with approximately 5 mL of water, shake gently, and flush the tube.
