Before preparing NITYR using an oral syringe
Lay out the prescribed number of NITYR tablets and syringes for your dose. Place the tablet or tablets on a clean flat surface.
How to prepare and take 1 NITYR tablet using a 5 mL oral syringe:
Step 1. Remove the cap from the 5 mL oral syringe.
Step 2. Remove the plunger from the oral syringe and place 1 whole NITYR tablet inside the oral syringe (See Figure A).
Step 3. Replace the plunger (See Figure B).
Step 4. Draw up 2.6 mL of room temperature water into the oral syringe. Each line on the barrel of the syringe is 0.2 mL. There may be some air in the oral syringe. Leave the air in the oral syringe (See Figure C).
Step 5. Replace the cap on the oral syringe and note the time. Let the oral syringe sit for at least the length of time below:
- 15 minutes for a 2 mg tablet
- 60 minutes for a 5 mg or 10 mg tablet
(See Figure D)
Step 6. Turn the oral syringe up and down for at least 30 seconds (See Figure E).
Step 7. Check the oral syringe to see if the NITYR tablet has broken apart into very small pieces and the pieces are evenly spread through the water (suspension) (See Figure F). Do not take the suspension if there are any large pieces of the NITYR tablet in the suspension or if there are any pieces of the tablet that are not evenly spread through the water.
If there are any pieces of the tablet that are not evenly spread through the water, let the oral syringe sit for 10 minutes.
Before giving the suspension, turn the oral syringe up and down for 30 seconds to continue to spread the pieces of NITYR tablet in the suspension.
Step 8. Remove the cap from the oral syringe (See Figure G).
Step 9. Place the tip of the oral syringe in the mouth. If giving to a child, place the tip of the oral syringe along the inner cheek of the child’s mouth (See Figure H).
Step 10. While keeping the oral syringe in the mouth, slowly push down on the plunger until a small amount of air is left in the oral syringe, between the plunger and the tip of the oral syringe (See Figure I). Do not press the plunger all the way down to the end of the syringe.
Step 11. Draw up an additional 2 mL of water into the oral syringe (See Figure J).
Step 12. Replace the cap on the oral syringe. Shake well to spread the remaining tablet pieces evenly through the water in the oral syringe (See Figure K).
Step 13. Remove the cap from the oral syringe (See Figure L).
Step 14. Place the tip of the oral syringe in the mouth. If giving to a child, place the tip of the oral syringe along the inner cheek of the child’s mouth (See Figure M).
Step 15. While keeping the oral syringe in the mouth, slowly push down on the plunger until the oral syringe is empty (See Figure N). In case any pieces of the tablet are still present in the oral syringe, repeat steps 11 through 15.
Step 16. After use, remove the plunger from the syringe barrel. Rinse the syringe and the plunger with water after each use and let it dry. Do not replace the plunger into the barrel of the oral syringe until ready to use again to allow it to dry. Do not throw away the oral syringe or plunger.
If you are not taking the water and NITYR tablet suspension as soon as it is prepared, complete steps 1 through 5. When you are ready to take the suspension, complete steps 6 through 16.
