Consumer Medicine Information

What is in this leaflet

This leaflet answers some common questions about NITYR tablets.

It does not contain all of the available information. Some of the information it contains may not apply to you. It does not take the place of talking to your doctor or pharmacist.

All medicines have benefits and risks. In deciding to give you NITYR, your doctor has weighed the risks of you taking NITYR against the expected benefits it will have for you.

Always follow the instructions that your doctor and pharmacist give you about NITYR.

If you have any concerns about taking this medicine, ask your doctor or pharmacist.

What NITYR are used for

NITYR contains the medicine Nitisinone. Nitisinone belongs to a group of medicines called ‘other alimentary and metabolism products’.

NITYR is used for the treatment of a disease called hereditary tyrosinaemia type 1. In this disease the body is unable to completely break down the amino acid tyrosine. Harmful substances will be formed and accumulated in the body.

NITYR block the breakdown of tyrosine and by doing so the harmful substances are not formed. However, tyrosine will remain in the body and therefore a special diet (with low tyrosine and phenylalanine content) must be followed when taking NITYR.

Your doctor may have prescribed this medicine for another use. If you want more information, ask your doctor.

NITYR is not addictive.

NITYR is only available on a doctor’s prescription

Before you take NITYR

You should not take NITYR if:

  • you are allergic to Nitisinone or any of the ingredients listed under ‘Product Description’ at the end of this leaflet. Signs of allergic reactions may include itchy skin, rash, shortness of breath and swelling of the face or tongue.
  • you are breastfeeding
  • the packaging shows signs of tampering.
  • the expiry date on the pack has passed.

Before you start to take NITYR

You must tell your doctor if:

You are pregnant or intend to become pregnant. Your doctor will discuss the possible risks and benefits of taking NITYR during pregnancy.

  • The use of NITYR during breast feeding has not been investigated. Ask your doctor for advice about breast feeding.
  • Hypersensitive to the active substance or to any of the excipients

If you have not told your doctor about any of the above, tell him/her before you start taking NITYR.

Taking other medicines

Tell your doctor or pharmacist if you are taking any other medicines, including any that you buy without a prescription from your pharmacy, supermarket or health food store.

If you are unsure about any medicine you are taking you should check with your doctor or pharmacist. They will have more information on medicines to be careful with or avoid while taking NITYR.

How to take NITYR

It is important to follow the directions that your doctor has given to you.

How much to take

Your doctor will tell you how many tablets to take each day.

Take NITYR only as prescribed by your doctor and follow his or her directions carefully. They may differ from the information contained in this leaflet.

When to take it

The usual daily dose is 1 mg/kg body weight per day divided in morning and evening administrations.

NITYR may be taken with or without food.

Instructions for administration of the product

The following instructions explain how to take NITYR tablets using an oral syringe if you are unable to swallow the tablet/s.


  • Only 1 or 2 NITYR tablets can be prepared in an oral syringe at one time.
  • Use a 5 mL oral syringe with a cap to prepare NITYR tablets in an oral syringe. Ask your pharmacist for your oral syringe. You may need more than one 5 mL oral syringe if you take more than 2 NITYR tablets for your prescribed dose.
  • Clean your hands well before preparing NITYR tablets using an oral syringe.

How to prepare and take 1 NITYR and 2 NITYR tablets using a 5 mL oral syringe:

  1. Remove the plunger and cap from the 5-mL oral syringe, insert one OR two tablets according to your doctor’s advice and replace the plunger.

  1. Draw up 2.6 mL for one tablet OR 5 mL for two tablets of room temperature water.

  1. Cap the oral syringe and leave it for at least 60 minutes.

  1. After 60 minutes, turn the oral syringe up and down for at least 30 seconds.

  1. Inspect the syringe to ensure the tablet/s has/have disintegrated before administration to the patient. Administer immediately, but only if the tablet/s has/have fully disintegrated.
  2. If the tablet/s is/are not fully disintegrated, leave the oral syringe for an additional 10 minutes. Before administration to the patient, turn the oral syringe up and down for 30 seconds to re-suspend the particles. Inspect the syringe again to ensure the tablet/s has/have disintegrated prior to administration to the patient. Do not administer unless the tablet/s has/have fully disintegrated.
  3. Administer immediately. However, if this is not possible, the suspension can be stored at room temperature in the capped oral syringe, protected from direct sunlight for up to 24 hours after adding water to the tablet. Discard after 24 hours.
  4. Uncap the oral syringe and administer the suspension in the patient’s mouth. To facilitate full administration, avoid pressing the plunger to the end of the oral syringe and leave a gap between the plunger and the oral syringe.

  1. Rinse the oral syringe by drawing up 2 mL of water. Cap the oral syringe and shake it well for 10 seconds to suspend any remaining particles.

  1. Uncap the oral syringe and administer the suspension into the patient’s mouth, this time fully pressing the plunger and ensuring the syringe is empty and no particles are left in the tip of the syringe.

  1. After use, remove the plunger from the oral syringe barrel. Rinse the oral syringe 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.

How to prepare and take more than 2 NITYR tablets using an oral syringe:

If more than two NITYR tablets are needed for the prescribed dose, prepare and take the prescribed dose following the instructions in “How to prepare and take 1 NITYR and 2 NITYR tablets using a 5 mL oral syringe”. You may need an extra oral syringe.

The following instructions explain how to crush NITYR tablets in applesauce if you are unable to swallow the tablet/s.

How to prepare and take NITYR tablets mixed in applesauce:

  1. Measure around one teaspoon of applesauce and transfer it into a clean glass.
  2. Take out two metal teaspoons. Position one NITYR tablet between two metal teaspoons and apply light pressure on the top spoon. The two teaspoons should overlap each other. Always crush one tablet at a time.
  3. Press and rotate the two teaspoons against each other repeatedly until the whole tablet is crushed into a fine powder.
  4. Carefully transfer the resulting powder to the applesauce in the glass. Make sure all the powder is transferred and no powder is left on the teaspoon.
  5. If more than one tablet is needed, repeat the procedure starting in Step 2 and collect all the resulting powder together in the glass.
  6. Mix the powder into the applesauce until all the powder is dispersed.
  7. Give the entire NITYR tablet-applesauce mixture to the patient’s mouth using a teaspoon. The mixture should be given immediately. If this is not possible, the mixture can be stored at room temperature, out of direct sunlight, for up to 2 hours after adding the powder to the applesauce. Discard any mixture after 2 hours.
  8. To make sure that there is no leftover applesauce mixture in the glass, add another teaspoon of applesauce to the glass and mix. Ensure any remaining applesauce is mixed well with the extra applesauce.
  9. Give the additional NITYR tablet-applesauce mixture immediately to the patient’s mouth using a spoon.
