• Do not use any granules left in the open packet.

Administration with Food

1. Place 3 to 4 ounces of applesauce, pudding or yogurt in a small clean container.

2. Mix the measured amount of granules in the applesauce, pudding or yogurt

3. Swallow applesauce/pudding/yogurt immediately. Do not chew the granules. Do not save the applesauce/pudding/yogurt for later use.

4. Drink at least 4 ounces of water.

Administration in Milk or Infant Formula

Xuriden can be mixed with milk or infant formula instead of the soft foods described above for patients receiving up to 3/4 teaspoon (2 grams) of Xuriden. After weighing the dose of Xuriden: 

1. Pour 5 mL of milk or infant formula into a 30 mL medicine cup.

2. Insert the tip of the oral syringe into the medicine cup and draw up 5 mL of milk/infant formula into the syringe.

3. Hold the syringe with the tip pointing upward. Pull down on the plunger until the plunger reaches 10 mL. This will add air to the syringe.

4. Place the cap over the tip of the syringe. Then invert the syringe so the syringe tip is pointing down, and remove the plunger.

5. Pour the measured amount of Xuriden granules into the syringe barrel and reinsert the syringe plunger. Do not push up on the plunger.

6. Gently swirl the syringe to mix the Xuriden granules with the liquid.

7. Turn the syringe so the syringe tip is pointing up. Then remove the syringe cap and push up on the plunger until the plunger reaches the 5 mL mark. This will remove air from the syringe.

8. Place the tip of the syringe in the patient’s mouth between the cheek and gum at the back of the mouth. Gently push the plunger all the way down.

9. Refill the syringe with another 5 mL of milk/infant formula.

10. Gently swirl the syringe to rinse any remaining Xuriden granules from the syringe barrel.
