1. What is Sapropterina Teva and what is it used for

This medication contains the active ingredient sapropterin, which is a synthetic copy of a substance naturally 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.

Sapropterina Teva is used to treat hyperphenylalaninemia (HPA) or phenylketonuria (PKU) in patients of any age. HPA and PKU are due to abnormally high levels of phenylalanine in the blood that can be harmful. Sapropterina 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 BH4 deficiency in patients of any age, in which the body cannot produce enough BH4. Because BH4 levels are very low, the body cannot properly use phenylalanine, and the levels of this amino acid increase, having harmful effects. By replacing the BH4 that the body cannot produce, Sapropterina Teva reduces the harmful excess of phenylalanine in the blood and increases tolerance to dietary phenylalanine.

2. What you need to know before taking Sapropterina Teva

Do not take Sapropterina Teva

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 to take Sapropterina Teva, 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, as blood phenylalanine levels may increase
• if you have a predisposition to seizures

When receiving treatment with sapropterin, your doctor will perform blood tests to check the phenylalanine and tyrosine content and decide whether to adjust the sapropterin dose or diet if necessary.

You should continue dietary treatment according to your doctor's recommendations. Do not change your diet without telling your doctor. Even if you take sapropterina, if your blood phenylalanine levels are not well controlled, you may experience serious neurological problems. Your doctor should continue to monitor your blood phenylalanine levels frequently during treatment with sapropterina, to ensure they are not too high or too low.

Other medications and Sapropterina Teva

Tell your doctor or pharmacist if you are taking, have recently taken, or may need to take any other medication. In particular, you should inform your doctor if you are using:

• levodopa (to treat Parkinson's disease)
• cancer treatments (e.g., methotrexate)
• antibiotics (e.g., trimethoprim)
• medications that cause blood vessel dilation (e.g., glyceryl trinitrate [GTN], isosorbide dinitrate [ISDN], sodium nitroprusside [SNP], molsidomine, minoxidil)

Pregnancy and breastfeeding

If you are pregnant or breastfeeding, think you may be pregnant, or plan to become pregnant, consult your doctor or pharmacist before using this medication.

If you are pregnant, your doctor will tell you how to properly control phenylalanine levels. 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 monitor dietary phenylalanine restriction before and during pregnancy.

If a strict diet does not satisfactorily reduce the amount of phenylalanine in the blood, your doctor will consider whether you should take this medication.

You should not use this medication during breastfeeding.

Driving and using machines

Sapropterina Teva is not expected to affect your ability to drive or use machines.

Sapropterina Teva contains sodium

This medication contains less than 1 mmol of sodium (23 mg) per tablet; it is essentially "sodium-free".

3. How to take Sapropterina Teva

Follow your doctor's instructions for taking this medication exactly. If you are unsure, consult your doctor again.

Dose for PKU

The recommended initial dose of Sapropterina Teva in patients with PKU is 10 mg per kilogram of body weight. Take Sapropterina Teva once a day, with a meal to increase absorption, and at the same time each day, preferably in the morning. Your doctor may adjust the dose, usually between 5 and 20 mg daily per kilogram of body weight, based on your condition.

Dose for BH4 deficiency

The recommended initial dose of Sapropterina Teva in patients with BH4 deficiency is 2 to 5 mg per kilogram of body weight. Take Sapropterina Teva 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 kilogram of body weight, based on your condition.

The following table is an example of how to calculate the appropriate dose

Method of administration

For patients with PKU, the total daily dose is taken once a day and at the same time each 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

Place the prescribed tablets in a glass or cup of water, as described exactly below, and stir until they dissolve.

The tablets may take a few minutes to dissolve. To help the tablets dissolve faster, you can crush them. You may see small particles in the solution that will not affect the effectiveness of the medication. Drink the dissolved Sapropterina Teva preparation with a meal within 15 to 20 minutes of preparation.

Do not ingest the capsule with the desiccant included in the bottle.

Use in patients with a body weight over 20 kg

Place the tablets in a glass or cup (120 to 240 ml) of water and stir until they dissolve.

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 tell you:

• the number of Sapropterina Teva tablets needed for a dose
• the amount of water needed to mix a dose of Sapropterina Teva
• the amount of solution to administer to the child for the prescribed dose

The child should drink the solution with a meal.

Administer the prescribed amount of solution to the child within 15 to 20 minutes of dissolving the tablets. If you cannot administer the dose to the child within 15 to 20 minutes of dissolving the tablets, you will need to prepare a new solution, as the unused solution should not be used after 20 minutes.

Materials needed to prepare and administer the dose of Sapropterina Teva to the child

• The number of Sapropterina Teva tablets needed for a dose
• A medicine cup with graduated 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 medicine cup and oral syringe (10 ml or 20 ml) if you do not have these materials.

Steps for preparing and taking the dose:

• Place the prescribed tablets in the medicine cup. Pour the amount of water indicated by your doctor (e.g., your doctor told you to use 20 ml to dissolve one Sapropterina Teva tablet) into the medicine cup. Check that the liquid level aligns with the mark on the medicine cup indicated by your doctor. Stir with the spoon or clean utensil until the tablets dissolve.
• If your doctor told you to administer only part of the solution, insert the tip of the oral syringe into the medicine cup. Slowly pull the plunger back to draw up the amount indicated by your doctor.
• Transfer the solution to a glass or dosing cup by slowly pushing the plunger until all the solution previously drawn into the oral syringe is inside (e.g., if your doctor told you to dissolve two Sapropterina Teva 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 draw up the 30 ml [e.g., 20 ml + 10 ml] of solution and transfer it to a glass or dosing cup). Use a 10 ml oral syringe for administering volumes ≤10 ml or a 20 ml oral syringe 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. Draw up the prescribed volume of prepared solution into the dosing cup and insert the tip of the oral syringe into the baby's mouth. Aim the tip of the oral syringe towards one of the cheeks. Slowly push the plunger, releasing a small amount at a time, until all the solution in the oral syringe is administered.
• Discard any remaining solution. Remove the plunger from the oral syringe body. 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 oral syringe body. Store the oral syringe and medicine cup for the next use.
