• If you are allergic to penicillamine.
• If you are breast-feeding.

Warnings and precautions

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.

Other medicines and PROCYSBI

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.

PROCYSBI with food and drink

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.

Pregnancy and breastfeeding

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. 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 use PROCYSBI”).

Driving and using machines

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.

PROCYSBI contains sodium

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

Dosing schedule

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.

Duration of treatment

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

Method of administration

You should take this medicine only by mouth.

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

• 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. Do not give gastro-resistant hard capsules to children under 6 years of age because they may not be able to swallow them and they may choke. For patients who cannot swallow the whole capsule, the gastro-resistant hard capsule may be opened and the contents may be sprinkled on food (such as apple sauce or berry jelly) or mixed in with an acidic drink (such as orange juice or any acidic juice) or water. Consult your child’s doctor for complete directions.
• Your medical treatment may 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.

If you take more PROCYSBI than you should

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 forget to take PROCYSBI

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.
