Ways to Take NITYR
NITYR (nitisinone) Oral Suspension
With NITYR, caregivers can create a suspension whenever and wherever they want by dissolving a tablet in an oral syringe:
- Fewer medication complexities with no refrigeration required.
- Quick preparation. Can be made as needed, with less than one minute of active preparation and administration time.
- Greater flexibility with on-the-go preparation. It can be administered any time between 60 minutes and 24 hours after preparation, giving patients more freedom.
- Accurate dosing each and every time. Patients receive the prescribed treatment without the risk of under or overdosing.
- Unlike pre-made liquid suspensions, there is no cake or foam build-up to contend with.
Since launch, 100% of the newborn babies prescribed NITYR had their medication shipped within 24 hours.*1
NITYR (nitisinone) Tablets with Applesauce
As your child grows and moves onto semi-solids, NITYR tablets can be crushed and mixed with applesauce.
- Accurate dosing each and every time. Patients receive the prescribed treatment without the risk of under or overdosing.
- Unlike pre-made liquid suspensions, there is no cake or foam build up to contend with.
- Flexibility around mealtimes as the mixture can be taken within 2 hours of it being made
NITYR (nitisinone) Tablets
NITYR tablets are very small and discreet2 and are available in 2 mg, 5 mg, and 10 mg strengths. They can be crushed and mixed with applesauce or taken on their own.
Many children prefer baby aspirin-sized tablets over solutions and suspensions3, and NITYR may also help minimize the natural challenges that come with the teenage years.
- Convenience of once daily dosing for qualified patients to reduce the impact on their busy schedule.**
- With NITYR there’s one less thing for your patients and caregivers to worry about as the medication doesn’t require refrigeration.
- Flexibility for your patients to spend more time socializing and advancing their education and career without the burden of “take with food” restrictions.
- Discretion when taking their medication around their friends due to the very small size of NITYR tablets.2
- 80% of adults prefer to take multiple smaller pills than a single large one.4
Instructions for Use
- Use the reusable syringe provided. Remove the plunger, add one NITYR tablet and replace the plunger.
- Draw up 2.6 mL of room temperature water.
- Put the cap back on and let the syringe sit for at least 60 minutes.
- Once you are ready to administer (you can administer up to 24 hours after adding water to the tablet), turn the oral syringe up and down for at least 30 seconds and check that no large lumps of tablet remain. If there are large lumps, let the syringe sit for a further 10 minutes, and then reinspect the syringe for any large lumps. Once no large lumps of tablet remain, turn the oral syringe up and down for at least 30 seconds before administering the medication.
- Take the cap off, place the syringe in the child’s mouth, and push down on the plunger until a small amount of air remains in the syringe. Do not press the plunger all the way to the end.
- Rinse the syringe by drawing up another 2 mL of water. Replace the cap and shake the syringe well.
- Take the cap off, place the syringe in the child’s mouth and push down on the plunger until it is completely empty.
