• If you are allergic to cysteamine (also known as mercaptamine) or any of the other ingredients of this medicine (listed in section 6).
• If you are allergic to penicillamine (this is not “penicillin”, but a medicine used for the treatment of Wilson’s disease).
• If you are breast-feeding.

Talk to your doctor or pharmacist before taking PROCYSBI.

• Since oral cysteamine doesn’t prevent deposits of cystine crystals in the eye, you should continue taking cysteamine eye drops as prescribed by your doctor.
• Whole cysteamine capsules should not be given to children under the age of 6 years due to the risk of choking (refer to section 3 “How to take PROCYSBI – Method of administration”).
• Serious skin lesions can occur in patients treated with high doses of cysteamine. Your doctor will routinely monitor your skin and bones and reduce or stop your treatment if needed (see section 4).
• Stomach and intestinal ulcers and bleeding can occur in patients receiving cysteamine (see section 4).
• Other intestinal symptoms including nausea, vomiting, anorexia and stomach ache can occur with cysteamine. Your doctor may interrupt and change your dose if these occur.
• Talk to your doctor if you have any unusual stomach symptoms or changes in stomach symptoms.
• Symptoms such as seizures, tiredness, sleepiness, depression, and brain disorders (encephalopathy) can occur with cysteamine. If such symptoms develop, tell your doctor who will adjust your dose.
• Abnormal liver function or reduced white blood cell count (leukopenia) can occur with use of cysteamine. Your doctor will routinely monitor your blood counts and liver function.
• Your doctor will monitor you for benign intracranial hypertension (or pseudotumor cerebri [PTC]) and/or swelling of the optic nerve (papilledema) associated with cysteamine treatment. You will receive regular eye examinations to identify this condition as early treatment can prevent vision loss.

Tell your doctor or pharmacist if you are taking, have recently taken, or might take any other medicines. If your doctor prescribes bicarbonate, do not take it at the same time as PROCYSBI; take bicarbonate at least one hour before or at least one hour after the medicine.

For at least 1 hour before and 1 hour after taking PROCYSBI try to avoid meals, which are rich in fat or proteins as well as any food or liquid that could decrease the acidity in your stomach, like milk or yogurt. If this is not possible, you can eat a small amount (about 100 grams) of food (preferably carbohydrates e.g. bread, pasta, fruits) during the hour before and after taking PROCYSBI.

Take the capsule with an acidic drink (such as orange juice or any acidic juice) or water. For children and patients who have problems to swallow, please refer to section 3 “How to take PROCYSBI – Method of administration”.

If you are pregnant or breast-feeding, think you may be pregnant or are planning to have a baby, ask your doctor or pharmacist for advice before taking this medicine.

You should not use this medicine if you are pregnant, particularly during the first trimester. Before starting the treatment, you should have a pregnancy test with negative result, while during the course of treatment you should use an adequate method of contraception. If you are a woman planning a pregnancy or become pregnant, seek immediate advice from your doctor about stopping therapy with this medicine as continued treatment may be harmful to the unborn baby.

Do not use this medicine if you are breastfeeding (see section 2 under “Do not take PROCYSBI”).

This medicine may cause some drowsiness. When starting therapy, you should not drive, use machines, or engage in other dangerous activities until you know how the medicine affects you.

This medicine contains less than 1 mmol sodium (23 mg) per dose, that is to say essentially “sodium-free.”

Take this medicine two times a day, every 12 hours. To get the most benefit from this medicine, try to avoid meals and dairy products for at least 1 hour before and 1 hour after PROCYSBI dosing. If this is not possible, you can eat a small amount (about 100 grams) of food (preferably carbohydrates e.g. bread, pasta, fruits) during the hour before and after PROCYSBI administration.

It is important to take PROCYSBI in a consistent way over time.

Do not increase or decrease the amount of medicine without your doctor’s approval.

The total usual dose should not exceed 1.95 g/m²/day.

Treatment with PROCYSBI should continue life-long, as instructed by your doctor.

You should take this medicine only by mouth.

In order for this medicine to work correctly, you must do the following:

• For patients who can swallow the whole capsule:
  Swallow the whole capsule with an acidic drink (such as orange juice or any acidic juice) or water. Do not crush or chew capsules or capsule contents. Children under 6 years of age may not be able to swallow gastro-resistant hard capsules and may choke them. You can give Procysbi to children under 6 years of age by opening the capsules and sprinkling the contents on food or liquid, as per the instructions given below.
• For patients who cannot swallow the whole capsule or who use a feeding tube:
  Sprinkling on food
  Open the gastro-resistant hard capsules and sprinkle the contents (granules) onto approximately 100 grams of food such as apple sauce or fruit jam.
  Gently stir the granules into the soft food, creating a mixture of granules and food. Eat the entire mixture. Then drink about 250 mL of an acidic drink (such as orange juice or any acidic juice) or water to ease the swallowing of the mixture. If you don’t eat the mixture immediately, you may refrigerate (2°C-8°C) it from the time of preparation to the time of administration and eat it within 2 hours of preparation. Nothing of the mixture should be saved beyond 2 hours
  Administering through feeding tube
  Open the gastro-resistant hard capsules and sprinkle the contents (granules) onto approximately 100 grams of apple sauce or fruit jam. Gently stir the granules into the soft food, creating a mixture of granules and the soft food. Administer the mixture by gastrostomy tube, nasogastric tube or gastrostomy jejunostomy tube using a catheter tip syringe. Before PROCYSBI administration: Unclasp the G-tube button and attach the feeding tube. Flush with 5 mL of water to clear the button. Draw the mixture up into the syringe. A maximum 60 mL mixture volume in a catheter tip syringe is recommended for use with a straight or bolus feeding tube. Place the opening of the syringe containing the PROCYSBI and food mixture into the opening of the feeding tube and fill completely with the mixture: pressing gently on the syringe and keeping the feeding tube horizontal during administration can help to avoid clogging issues. Using a viscous food such as apple sauce or fruit jam at a rate of about 10 mL every 10 seconds until the syringe is completely empty is suggested to avoid clogging. Repeat the above step until all of the mixture is given. After PROCYSBI administration, draw 10 mL of fruit juice or water up into another syringe and flush the G-tube ensuring that none of the PROCYSBI and food mixture gets stuck in the G-tube. If you don’t consume the mixture immediately, you may refrigerate (2°C-8°C) it from the time of preparation to the time of administration and consume it within 2 hours of preparation. Nothing of the mixture should be saved beyond 2 hours. Consult your child’s doctor for complete instructions on how to properly administer the product through feeding tubes and if you experience clogging issues.
  Sprinkling in orange juice or any acidic fruit juice or water
  Open the gastro-resistant hard capsules and sprinkle the contents (granules) into about 100 to 150 mL of acidic fruit juice (such as orange juice or any acidic juice) or water. Mix the PROCYSBI drink mixture gently for 5 minutes, either mixing in a cup or shaking in a covered cup (e.g., “sippy” cup) and drink the mixture.
  If you don’t drink the mixture immediately, you may refrigerate (2°C-8°C) it from the time of preparation to the time of administration and drink it within 30 minutes after preparation.
  Nothing of the mixture should be saved beyond 30 minutes.
  Administering a drink mixture by oral syringe
  Aspirate the drink mixture into a dosing syringe and administer it into the mouth directly.
  If you don’t consume the mixture immediately, you may refrigerate (2°C-8°C) it from the time of preparation to the time of administration and consume it within 30 minutes after preparation. Nothing of the mixture should be saved beyond 30 minutes.
• Your doctor may recommend or prescribe to include, in addition to cysteamine, one or more supplements to replace important electrolytes lost through the kidneys. It is important to take these supplements exactly as instructed. If several doses of the supplements are missed or weakness or drowsiness develops, call your doctor for instructions.
• Regular blood tests to measure the amount of cystine inside white blood cells and/or the concentration of cysteamine in the blood are necessary to help determine the correct dose of PROCYSBI. You or your doctor will arrange for these blood tests to be performed. These tests must be obtained 12.5 hours after the evening dose the day before, and therefore 30 minutes after the following morning dose is given. Regular blood and urine tests to measure the levels of the body’s important electrolytes are also necessary to help you or your doctor correctly adjust the doses of these supplements.

You should contact your doctor or the hospital emergency department immediately if you have taken more PROCYSBI than you should. You may become drowsy.

If you missed a dose of medicine, you should take it as soon as possible. However, if it is within 4 hours of the next dose, skip the missed dose and go back to the regular dosing schedule.

Do not take a double dose to make up for a forgotten dose.

• Severe allergic reaction (seen uncommonly): Get emergency medical help if you have any of these signs of an allergic reaction: hives; difficulty breathing; swelling of face, lips, tongue, or throat.

If any of the following side effects occur, please contact your doctor immediately. Since some of these side effects are serious, ask your doctor to explain their warning signs.

Common side effects (may affect up to 1 in 10 people):

• Skin rash: Tell the doctor right away if you get a skin rash. PROCYSBI may need to be temporarily stopped until the rash goes away. If the rash is severe, your doctor may discontinue cysteamine treatment.
• Abnormal liver function on blood tests. Your doctor will monitor you for this.

Uncommon side effects (may affect up to 1 in 100 people):

• Skin lesions, bone lesions, and joint problems: Treatment with high doses of cysteamine can cause skin lesions to develop. These include skin striae (which are like stretch marks), bone injuries (such as fractures), bone deformities, and joint problems. Examine your skin while taking this medicine. Report any changes to your doctor. Your doctor will monitor you for these problems.
• Low white blood cell count. Your doctor will monitor you for this.
• Central nervous system symptoms: Some patients taking cysteamine have developed seizures, depression, and become too sleepy (excessive sleepiness). Tell your doctor if you have these symptoms.
• Stomach and intestinal (gastrointestinal) problems: Patients taking cysteamine have developed ulcers and bleeding. Tell your doctor right away if you get stomach ache or throw up blood.
• Benign intracranial hypertension, also called pseudotumor cerebri, has been reported with cysteamine use. This is a condition where there is high pressure in the fluid around the brain. Tell your doctor right away if you develop any of the following symptoms while taking PROCYSBI: buzzing or “whooshing” sound in the ear, dizziness, double vision, blurry vision, loss of vision, pain behind the eye or pain with eye movement. Your doctor will monitor you with eye examinations to find and treat this problem early. This will help lessen the chance of loss of eyesight.
