1. What is Sapropterin Tarbis and what is it used for
Sapropterin contains the active ingredient sapropterin, which is a synthetic copy of a substance found in the body called tetrahydrobiopterin (BH4). BH4 is necessary in the body to convert an amino acid called phenylalanine into another amino acid called tyrosine.
Sapropterin is used to treat hyperphenylalaninemia (HPA) or phenylketonuria (PKU) in patients of any age. HPA and PKU are caused by abnormally high levels of phenylalanine in the blood that can be harmful. Sapropterin reduces these levels in some patients who respond to BH4 and may help increase the amount of phenylalanine that can be included in the diet.
This medication is also used to treat a hereditary disease called tetrahydrobiopterin deficiency in patients of any age, in which the body cannot produce enough BH4. Because BH4 levels are very low, the body cannot use phenylalanine properly, and levels of this amino acid increase, having harmful effects. By substituting the BH4 that the body cannot produce, sapropterin reduces the damaging excess of phenylalanine in the blood and increases tolerance to phenylalanine in the diet.
2. What you need to know before starting Sapropterin Tarbis
Do not take Sapropterina Tarbis
If you are allergic to sapropterin or any of the other components of this medication (listed in section 6).
Warnings and precautions
Consult your doctor or pharmacist before starting sapropterin, especially:
- If you are 65 years or older
- If you have kidney or liver problems
- If you are ill. It is recommended to consult with your doctor in case of illness since blood phenylalanine levels may increase
- If you have a predisposition to seizures
When receiving treatment with sapropterin, your doctor will perform blood tests to verify the content of phenylalanine and tyrosine and decide to adjust the dose of sapropterin or the diet as necessary.
You must continue the dietary treatment according to your doctor's recommendations. Do not change your diet without informing your doctor. Even when taking sapropterin, if your blood phenylalanine levels are not well controlled, you may experience severe neurological problems. Your doctor must continue to monitor your blood phenylalanine levels frequently during sapropterin treatment,to ensure they are not too high or too low.
Use of Sapropterina Tarbis with other medications
Inform your doctor or pharmacist if you are taking, have taken recently, or may need to take any other medication. In particular, you must inform your doctor if you are using:
- levodopa (to treat Parkinson's disease)
- medications for cancer treatment (e.g. methotrexate)
- medications for bacterial infections (e.g. trimethoprim)
- medications that cause vasodilation (e.g. glyceryl trinitrate [GTN], isosorbide dinitrate [ISDN], sodium nitroprusside [SNP], molsidomine, minoxidil).
Pregnancy and breastfeeding
If you are pregnant or breastfeeding, or think you may be pregnant, consult your doctor or pharmacist before using this medication.
If you are pregnant, your doctor will instruct you on how to control your phenylalanine levels properly. If they are not strictly controlled before pregnancy or when you become pregnant, it may be harmful to you and your baby. Your doctor will supervise the restriction of phenylalanine intake with diet before and during pregnancy.
If a strict diet does not reduce phenylalanine levels sufficiently in the blood, your doctor will consider whether you should take this medication.
You should not use this medication during breastfeeding.
Driving and operating machinery
Sapropterin is not expected to affect your ability to drive and operate machinery.

3. How to Take Sapropterin Tarbis
Follow the exact administration instructions for this medication as indicated by your doctor. If in doubt, consult your doctor again.
Dose for PKU
The recommended initial dose of sapropterin in patients with PKU is 10 mg per kg of body weight. Take sapropterin once a day, with a meal to increase absorption, and at the same time every day, preferably in the morning. Your doctor may adjust the dose, generally between 5 and 20 mg daily per kg of body weight, according to your condition.
Dose for BH4 deficiency
The recommended initial dose of sapropterin in patients with BH4 deficiency is 2 to 5 mg per kg of body weight. Take sapropterin with a meal to increase absorption. Divide the total daily dose into 2 or 3 doses administered throughout the day. Your doctor may adjust the dose up to 20 mg daily per kg of body weight, according to your condition.
The following table is an example of how to calculate the appropriate dose
Body weight (kg) | Number of 100 mg tablets (dose of 10 mg/kg) | Number of 100 mg tablets (dose of 20 mg/kg) |
10 | 1 | 2 |
20 | 2 | 4 |
30 | 3 | 6 |
40 | 4 | 8 |
50 | 5 | 10 |
Administration form
For patients with PKU, the total daily dose is taken once a day and at the same time every day, preferably in the morning.
For patients with BH4 deficiency, the total daily dose is divided into 2 or 3 doses distributed throughout the day.
Use in all patients
Deposit the prescribed tablets in a glass or cup of water, exactly as described below, and stir until dissolved.
The tablets may take a few minutes to dissolve. To dissolve the tablets faster, you can crush them. You may observe small particles in the solution that will not affect the efficacy of the medication. Drink the prepared sapropterin solution with a meal within 15 or 20 minutes of preparation.
Do not ingest the desiccant capsule included in the bottle.
Use in patients with a body weight over 20 kg
Deposit the tablets in a glass or cup (120 to 240 ml) of water and stir until dissolved.
Use in children up to 20 kg of body weight
The dose is based on body weight, which will change as the child grows. Your doctor will instruct you:
- the number of sapropterin tablets needed for a dose
- the amount of water needed to mix a dose of sapropterin
- the amount of solution to administer to the child for the prescribed dose
The child should drink the sapropterin solution with a meal.
Administer the child the prescribed amount of solution within 15 or 20 minutes of preparation. If you cannot administer the dose to the child within 15 or 20 minutes of preparation, you will need to prepare a new solution, as unused solution should not be used after 20 minutes.
Materials needed to prepare and administer the child's sapropterin dose
- The number of sapropterin tablets needed for a dose
- A medication cup with markings corresponding to 20, 40, 60, and 80 ml
- A glass or cup
- A spoon or clean utensil for stirring
- An oral syringe (graduated in 1 ml divisions; a 10 ml syringe for administering volumes ≤10 ml or a 20 ml syringe for administering volumes >10 ml)
Ask your doctor for the medication cup to dissolve the tablets and the oral syringe of 10 ml or 20 ml if you do not have these materials.
Steps for preparation and taking the dose:
- Deposit the prescribed tablets in the medication cup. Pour the indicated amount of water into the medication cup (e.g., your doctor told you to use 20 ml to dissolve a 100 mg sapropterin tablet). Check that the amount of liquid aligns (with the corresponding marking on the medication cup) with the amount indicated by your doctor. Stir with the spoon or clean utensil until the tablets dissolve.
- If your doctor told you to administer only a part of the solution, insert the tip of the oral syringe into the medication cup. Pull the plunger back slowly to extract the indicated amount.
- Next, transfer the solution to a glass or dosing cup by pushing the plunger slowly until all the previously extracted solution is in the oral syringe (e.g., if your doctor told you to dissolve two 100 mg sapropterin tablets in 40 ml of water and administer 30 ml to the child, you will need to use the 20 ml oral syringe twice to extract the 30 ml (e.g., 20 ml + 10 ml) of solution and transfer it to a glass or dosing cup). Use an oral syringe of 10 ml for administering volumes ≤10 ml or an oral syringe of 20 ml for administering volumes >10 ml.
- If the baby is too small to drink from a glass or cup, you can administer the solution using the oral syringe. Extract the prescribed volume of prepared solution from the dosing cup and insert the tip of the oral syringe into the baby's mouth. Point the tip of the oral syringe towards one cheek. Push the plunger slowly, releasing a small amount at a time, until you administer all the solution contained in the oral syringe.
- Discard any remaining solution. Extract the plunger from the body of the oral syringe. Wash both parts of the oral syringe and the dosing cup with warm water and let them air dry. When the oral syringe is dry, reinsert the plunger into the body of the oral syringe. Store the oral syringe and medication cup for the next use.
