ORFADIN® Oral Suspension


Consumer Medicine Information

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.

Before you take ORFADIN

When you must not take it

Do not take ORFADIN if you have an allergy to:

  • any medicine containing nitisinone.
  • any of the ingredients listed at the end of this leaflet.

Some of the symptoms of an allergic reaction may include:

  • shortness of breath
  • wheezing or difficulty breathing
  • swelling of the face, lips, tongue or other parts of the body
  • rash, itching or hives on the skin

Do not breast-feed if you are taking this medicine.

Do not take this medicine after the expiry date printed on the pack or if the packaging is torn or shows signs of tampering. If it has expired or is damaged, return it to your pharmacist for disposal.

If you are not sure whether you should start taking this medicine, talk to your doctor.

Before you start to take it

Tell your doctor if you have allergies to any other medicines, foods, preservatives or dyes.

Tell your doctor about your diet regimen. Your doctor will advise you on how to maintain a diet restricted in tyrosine and phenylalanine content.

Tell your doctor if you are pregnant or plan to become pregnant or are breastfeeding. Your doctor can discuss with you the risks and benefits involved.

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

Taking other medicines

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

Some medicines and ORFADIN may interfere with each other. These include:

  • warfarin, a medicine used to thin your blood
  • phenytoin, a medicine used to treat epilepsy
  • furosemide (frusemide), a diuretic

These medicines may be affected by ORFADIN or may affect how well it works. You may need different amounts of your medicines, or you may need to take different medicines.

Your doctor and pharmacist have more information on medicines to be careful with or avoid while taking ORFADIN.

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

Figure 1A

  1. Before measuring the first dose, shake the unopened bottle vigorously for AT LEAST 20 SECONDS until the solid cake at the bottom of the bottle is completely dispersed (Figure 1A).

Figure 1B

  1. Remove the child resistant screw cap by pushing it down firmly and turning it anti-clockwise (Figure 1B).

Figure 1C

  1. 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.

How to prepare and administer a dose of medicine

Figure 2A

  1. Shake the bottle vigorously for AT LEAST 5 SECONDS (Figure 2A).

Figure 2B

  1. Immediately thereafter, open the bottle by removing the child resistant screw cap (Figure 2B).

Figure 2C

  1. Push the syringe plunger down completely
  2. Keep the bottle in an upright position and insert the oral syringe firmly into the hole of the adaptor on the bottle (Figure 2C).

Figure 2D

  1. Carefully turn the bottle upside down with the oral syringe firmly in place (Figure 2D).
  2. 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.
  3. Turn the bottle to an upright position again. Disconnect the oral syringe by gently twisting it out of the bottle adaptor.
  4. 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.
  5. Immediately screw the child resistant cap onto the bottle. The bottle adaptor should not be removed.
  6. 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.


Clean the oral syringe IMMEDIATELY after use with water. Separate barrel and plunger and rinse both with water. Shake off excess water and leave the disassembled oral syringe to dry until it is required for the next dose.

When to take it

If you are taking ORFADIN twice daily, take your first dose in the morning and your second dose in the evening.
