What is in this leaflet

This leaflet answers some common questions about ORFADIN oral suspension. It does not contain all the available information. It does not take the place of talking to your doctor or pharmacist.
All medicines have risks and benefits. Your doctor has weighed the risks of you taking ORFADIN against the benefits they expect it will have for you.
If you have any concerns about taking this medicine, ask your doctor or pharmacist.
Keep this leaflet with the medicine.
You may need to read it again.

What ORFADIN is used for

ORFADIN contains a medicine called nitisinone which is used for the treatment of a disease called hereditary tyrosinaemia type 1 (HT-1). In this disease the body is unable to completely break down the amino acid tyrosine. Harmful substances can form and accumulate in the body.
ORFADIN blocks 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 that is low in tyrosine and phenylalanine content must be followed when taking ORFADIN.
Nitisinone belongs to a group of medicines called 'other alimentary and metabolism products'.
Ask your doctor if you have any questions about why this medicine has been prescribed for you.
Your doctor may have prescribed it for another reason.
ORFADIN is not addictive.
ORFADIN is available only with a doctor's prescription.

How to take ORFADIN oral suspension

Follow all directions given to you by your doctor or pharmacist carefully.
They may differ from the information contained in this leaflet.
The oral suspension is taken with an oral syringe directly in the mouth without dilution.
ORFADIN must not be injected.
Do not attach a needle to the syringe.
If you do not understand the instructions, ask your doctor or pharmacist for help.
Your doctor or pharmacist can advise you how to use the oral syringe correctly.

How much to take

The recommended starting dose is 1 mg/kg body weight /day divided in 2 doses administered orally. Your doctor will prescribe the correct dose for you.
Your doctor may change your total dose from twice a day to once a day if you weigh more than 20 kg and you have been taking ORFADIN twice daily for at least 4 weeks.
Your doctor will adjust your ORFADIN dose based on your response to ORFADIN and your test results.

How to take it

Take ORFADIN with food.

How to prepare the dose to be administered

The dose that your doctor prescribes you should be given in mL of suspension and not in mg. This is because the oral syringe which is used to withdraw the correct dose from the bottle is marked in mL.
If your prescription is in mg, contact your pharmacist or doctor for advice.
The pack contains a bottle of medicine with a cap, a bottle adaptor and three oral syringes (1 mL, 3 mL and 5 mL). Always use one of the oral syringes provided to take the medicine.
The 1-mL oral syringe (the smallest oral syringe) is marked from 0.1 mL to 1 mL with minor 0.01 mL graduations. It is used for measuring doses of up to 1 mL.
The 3 mL oral syringe (the middle sized oral syringe), is marked from 1 mL to 3 mL with minor 0.1 mL graduations. It is used for measuring doses of more than 1 mL and up to 3 mL.
The 5 mL oral syringe (the largest oral syringe), is marked from 1 mL to 5 mL with minor 0.2 mL graduations. It is used for measuring doses of more than 3 mL.
It is important that you use the correct oral syringe when taking the medicine. Your doctor, pharmacist or nurse will advise which oral syringe to use depending on the dose that has been prescribed.
Follow the instructions given below for dose preparation and administration carefully, in order to ensure that the correct dose is administered.

How to prepare a new bottle of ORFADIN oral suspension before first time use

Before taking the first dose, shake the bottle vigorously since during long-term storage the particles will form a solid cake at the bottom of the bottle.

1. Remove the bottle from the refrigerator. Write the date when the bottle should be discarded in the space provided on the bottle label, which is 2 months after it is first opened

4. Place the open bottle upright on a table. Push the plastic adaptor firmly into the neck of the bottle as far as you can (Figure 1C). Leave the plastic adaptor in place for the duration of the use of this bottle of medicine. Once the plastic adaptor is firmly in place, if you do not intend to administer the first dose now, close the bottle by screwing the child resistant cap back onto the bottle. If you intend to administer the first dose now, do not close the bottle but instead follow the instructions below from Step 3 (Figure 2C) onwards.

Follow the instructions below for all subsequent dosing.

5. Carefully turn the bottle upside down with the oral syringe firmly in place (Figure 2D).

6. In order to withdraw the prescribed dose (mL), pull the plunger back SLOWLY until the top edge of the black ring is exactly level with the line marking the required dose (Figure 2D). If any air bubbles are observed inside the filled oral syringe, push the plunger into the syringe barrel until the air bubbles are expelled. Then pull the plunger back again until the top edge of the black ring is exactly level with the line marking the dose.

7. Turn the bottle to an upright position again. Disconnect the oral syringe by gently twisting it out of the bottle adaptor.

8. The dose should be administered in the mouth immediately (without dilution) in order to avoid caking in the oral syringe. The oral syringe must be emptied SLOWLY to allow swallowing; rapid squirting of the medicine may cause choking.

9. Immediately screw the child resistant cap onto the bottle. The bottle adaptor should not be removed.

10. The opened bottle of medicine may be stored at a temperature below 25°C or in the refrigerator (2-8°C) and must be discarded 2 months after opening. The date it should be discarded should be noted on the bottle label.
